Snorkelling at John Pennekamp Coral State Park

Well it only took nine months, but we finally sorted ourselves out for long enough to take a snorkelling trip off the Florida Keyes and it was beautiful!

John Pennekamp park at Key Largo

We booked a trip with a tour operator in the John Pennekamp Coral State Park and headed about five miles offshore to the Key Largo Dry Rocks reef where we were treated to an awesome array of fish (as well as a sadly not-photographed 2 m-long nurse shark!) and a beautiful reef of corals and a TON of soft corals (like seafans and black corals).
There were a TON of soft corals forming the reef

Seafans everywhere!

Oh aye - Jesus was there too! This is a bronze statue called "Christ of the Abyss" and it sits at around 6 m depth just off the reef. Apparently it was placed there in 1965 and has been gradually accumulating marine life ever since. It's also become a tradition for snorkelers and divers to touch the statue's hands.

Dive Guide: 5th Layby on the Left (Loch Creran)

Site Summary
I don’t know if this site has a real name, but this one is at least descriptive! From the one entrance point you have the choice of diving one of three shallow rocky reefs, all of which are at depths of around 3m - 25m. The off-reef areas are ideal for training on a sandy seafloor, but the real attractions here are the serpulid worms which form beautiful, fragile reefs with their calcareous tubes. For some reason (no-one knows why), this loch is the only site in the world where these worms form large reefs like this and they are well worth seeing.

Type: Shore dive (rocky reef / serpulid reefs)
Depth: 3m-25m 
Tides: None
Suitable for: All diver grades (but good buoyancy essential near serpulid reefs)

5th Layby on the left site access.

To get to this site, drive north along the A828 towards Fort William, past the Sealife Centre, then turn left at the next roundabout and go under the bridge at the north of Loch Creran. From there (believe it or not!), it’s the 5th passing place on the left. There’s a large parking space there which can fit 4-5 cars. 

Site Access
From the parking bay,  you'll see a path and steps leading down to the shore. It can get a bit slippery underfoot when it's wet or icy so watch out, but basically you just walk straight down the beach and wade in!

Underwater
You have a couple of options for your dives at this site. See below for details. 

Approximate map of the 5th Layby dive site. Click to enlarge.

Once under the water, you have a few choices to make. 

Option 1: If you head straight out from the shore, you'll swim over a sandy seabed to a depth of around 6m where you'll find a small rocky reef. It slopes down quite steeply to a depth of around 10m and at some point someone has tried to build an artificial reef out of old tyres, so you should find those pretty easily. It's a pretty small area though, so you should see most of it within about 20-30 minutes depending on how thoroughly you explore!

Option 2: Keep the line of rocks on your left and follow them out into the water. As you drop down, you'll see a stretch of bedrock on your left which is covered in mussels and horse mussels. Then just keep this rock face on your left and follow it round to about 12-15m. At that point, you'll come to a bend in the rock and you have two more choices: Either follow the rock round to the left a little then double-back over the top of the bedrock slope (option 2a), or head to the right and explore the boulders further out (option 2b).

Option 2a: Head back up and over the bedrock to a depth of about 6m and then search around and you should find a large serpulid reef (approximately 1m high) which is well worth a look, as well as some smaller colonies. They are extremely fragile though, so do not touch them and do NOT swim over them! From there, continue onwards and you'll get back to your entry point.

Option 2b: This is a route I've only ever taken once, so I don't know it as well as the others. But, if you head out towards the right away from the bedrock slope, you'll find yourself in a boulder field which has some nice life on it. Just retrace your steps to get back or follow Option 2a.

Whichever option you choose, you may find you run into a bit of current once you get past the end of the bedrock slope, but it never gets very strong here and you can swim against it quite easily.

Recommended Equipment
Torch

What to See
The serpulid worm reefs are really the main attraction here, but there is a LOT of life on these reefs and they are lovely dives even if you miss the worms. There is a lot of encrusting life over the rock surfaces including plumose anemones, cup corals, Sagartiogeton sp., crabs, fan worms, soft corals and sponges. There’s not usually a lot in the way of fish life, although I’ve seen thornback rays here and quite a few pipefish. In the shallows there are large stands of Ascophylllum seaweeds and horse mussel beds to investigate too which usually have loads of little animals living in amongst them.
Visibility is usually fairly good, but varies a great deal depending on prevailing weather conditions and tide. If you dive here after a period of heavy rain and on an ebb tide the visibility can drop to almost nothing.

On the surface it's pretty common to see seals and otters here too so keep an eye out for those!

Dive Guide: The Caves (Loch Long)

Site Summary
The Caves is a very cool little site in Loch Long which is essentially a steep slope of large boulders with the gaps between them forming 'caves' for marine life, and there are loads of big plumose anemones  and other filter feeding animals all over the rocks. There are quite a lot of fish around this area too though, which makes it a popular fishing spot so fishing line is unfortunately a danger here and carrying a knife or pair of shears is a must. 

Type: Shore dive (rocky reef)
Depth: 0m-33m
Tides: None
Suitable for: Experienced ocean divers+ Good buoyancy required.
Notable hazards: Fishing line (entanglement) / awkward entry & exit.


Getting there and getting in
From Google Maps. Click to enlarge.

There's space for 2 cars to park here, then it's a bit of a scramble down to the water's edge. 

The Caves dive site is about 2 miles south of Arrochar on the A814. There's a small parking place by the side of the road which has enough room for two cars or a minibus to park in, so space is pretty limited. It's a very popular site for sea anglers as well, and they tend to arrive early, so unless you get lucky it would be worthwhile having a Plan B just in case you can't get in here.

Site Access
From the parking place, you have two options to get down to the water's edge, but both are pretty awkward. The first option (1) is to scramble down through the culvert that runs under the road and down that way. The second (2) is to follow the little, narrow path that runs down to the shore from the other side of the bridge. Both options are steep and can be very slippery if it's been raining!

A lot of the shoreline along this part of the loch does look rather similar from the water, so it's definitely worth leaving a marker on the shore if you're not sure if you'll be able to find your way back to the right spot again to get out. The only way out is the way you went in (the rest of the shore here is too steep to climb) so you need to get back to where you started!

Underwater
Approximate underwater map of The Caves dive sites.

Underwater, the site is comprised largely of a steep boulder slope leading down in steps from the surface to a flat, muddy seabed at around 30m-33m depth. It's nice all the way down though, so you can just pick your depth. If you get a day with decent visibility though, there is a stunning view from the bottom of the reef looking back up it towards the surface!

The site is relatively easy to navigate - just keep the slope on your left as you head out and down, then work your way back keeping the slope on your right.

WARNING: There is a LOT of loose fishing tangled in the rocks here so a decent torch and a pair of line cutters are absolutely essential. I know a lot of people who've got snagged here before and it can be extremely dangerous.

Recommended Equipment
Torch (essential)
Line cutters (essential)
Glow stick / flag to mark exit point

Things to See
I've not been to this site in a while, but there used to be lots of fish here, including pollock and other white fish, and it was a good site for dragonets and gurnards too. There are loads of filter-feeding animals too which take advantage of the elevation from the rocks to feed in the current including big plumose anemones, dead-mens fingers and the ubiquitous (for Loch Long!) sealochs anemone. It's also a cool place to see some different starfish like the Bloody Henry


There are a LOT of filter feeders here, making this a beautiful scenic dive site.

Dive Guide: A-Frames (Loch Long)

Site Summary
This dive site is probably one of the most-used training sites on the west coast, and often becomes very busy at weekends when dive clubs or training centres descend on it from all around the country! The main attractions of the site are the 'A-frames' which are the concrete supports of an old (now very ruined) structure which provide an artificial reef habitat for quite a lot of marine life. Otherwise the site lies over a gently sloping silty, sandy seabed and is ideal for novices and diver training.

Type: Shore dive (rocky / manmade reef)
Depth: 3m-20m
Tides: None
Suitable for: All diver grades
Notable hazards: Currents can be fairly strong below 20-22m.


Getting there and getting in
From Google Maps. Click to enlarge.


There's a good big car park at the A-frames that will accommodate around 15 cars. It will fill up quickly on busy days though! 

The A-frames are found beside the Finnart Oil Terminal on the A814, about 2.5 miles north of Garelochead or 6.5 miles south of Arrochar. There's space to park several cars right beside the site entrance in a relatively large car park, which helps to keep everyone safely away from the main road!

Site Access


Access to the waters edge 

Access to the site is down a short, but narrow little path to the water's edge. It can be a little bit of a scramble though, so watch out. Since it's a single file path, it's polite to give priority to divers who are exiting the water before climbing down yourself. At high tide, the water comes all the way up to the wall, but you can expect a bit of a longer walk if it's low tide. Once you're there, just wade straight in!

Underwater
Approximate map of A-Frames dive site. Click to enlarge.

Once you're in the water, finding your way around is nice and straightforward and essentially requires you to just head straight out from the shore and you'll find plenty of debris and bits of concrete to investigate, including some long concrete 'pillars' which usually have quite a lot of life living underneath them.


Despite this being the one site I've probably dived more often than any other, I think I've only actually got to see the A-Frames themselves maybe a handful of times because I'm usually teaching trainees in shallow water! Still, if you want to find the main frame, it's easiest to use a compass.

Standing at the entrance point, take a bearing towards the white lighthouse on the far shore of the loch (which should be due north). Start your dive and follow your compass, but remember to use your pilotage skills as well (i.e. 'leapfrog' between closer targets that line up on your bearing) because the amount of waste metal amongst the debris can make your compass go a bit weird! 

Keep on that heading until you reach approximately 20m and then start searching around the area if need be until you find it. It is a pretty small target (maybe 5m square) but you should be able to find it ok! I have recently been informed that there are actually four 'A-frames' at this site, so if I manage to find them I'll get you an update.

NOTES: The oil terminal itself is still in use and boats are frequently moored up here. Don't dive past the fence!

The current can be strong here at depths below approximately 20m so watch out for that if you are planning a deeper dive. 

Recommended Equipment
Torch

Compass

Things to See

There is a reasonable amount of marine life to see at the A-frames if you're able to go and look for it, though I don't think there's anything particularly rare. There are always shrimp underneath the concrete pillars, and you can also usually see the occasional plumose anemone, dead man's fingers or peacock fan worms on the more elevated parts of the structures. There are loads of crabs and starfish and plenty of 'buckie' whelks as well which you might see mating or laying eggs if you go early in the year. On the A-frames themselves you'll see a lot more encrusting filter feeders like the soft corals and fan worms and it's definitely the highlight of the dive if you can find it!

Visibility here is extremely variable, largely due to the high numbers of divers who use the site at weekends.

Dive Guide: Conger Alley (Loch Long)

Site Summary
Conger Alley is shore dive I've done a LOT over the years! It's made up of two rocky reefs over a gently sloping sandy seabed and there's usually a decent amount of marine life to see including conger eels if you're lucky. Situated near the north end of Loch Long, it's sheltered from a lot of bad weather by the surrounding hills and doesn't get much in the way of currents which makes it an ideal site for novices or diver training. 

Type: Shore dive (rocky reef)
Depth: 6m-30m 
Tides: None
Suitable for: All diver grades
Notable hazards: Traffic on A83

Getting there and getting in
From Google Maps. Click to enlarge.
If you don't park at the 'proper' parking place, you can fit 3-4 cars at the side of the road here in the mud. The site entrance is marked with the arrow.

Conger Alley sits right on the side of the A83, just 2.5 miles north of Arrochar. There's space to park several cars about 500m away in a large, tarmaced parking place, or if there aren't too many of you it's possible to park at the side of the road in the mud just beside the Goldberry Cottage B&B. It's a bit of a squeeze there though and you will be very close to the (very fast) main road.

WARNING! The traffic on this part of the A83 goes VERY fast as this stretch is one of the only good places to overtake for several miles. As such, cars are often travelling on the wrong side of the road so be careful! Lorries and heavy traffic are also a common feature.

Site Access
Access is very easy. The path is found directly opposite the white cottage on the side of the road.

Wherever you decide to park, there is a small pavement on the opposite side of the road where you can set up your kit and which will get you safely to the site itself. Access to the shore is via a small path directly opposite Goldberry Cottage B&B.

It's a pretty good option when the weather's awful too since the A83 is usually open at least as far as Arrochar. 

The path can be a little slippery when it's wet, but it's in pretty good condition and once you're on the beach it's an easy walk to the water. Just follow the line of boulders and wade in.

Underwater

Approximate map of Conger Alley dive site. 

Once you're in the water, finding the reef is nice and straightforward. Heading out from the shore, head diagonally left away from the shore down until you get to around 10-15m water depth. At this point, don't go any deeper and continue along the slope for a few minutes until you reach the reef. It is a relatively long and boring swim over a fairly featureless sandy bottom, but as long as you're at the correct depth you will definitely reach the shallow reef.

TOP TIP: Watch out for sealochs anemones as you head towards the reef. The boulders at Conger Alley are covered in them, and you'll see them start to appear on the seabed as you get closer to the reef.

When you get to Conger Alley itself, you have the choice of two reefs to explore. I've never dived the 'deep' reef myself, but you'll find it by heading downslope from the 'shallow' reef to a depth of around 25-30m or so depending on the tide. I believe there are usually more conger eels at the deeper reef so if you're qualified and happy with the depth it might be worth a look.

Otherwise, you can carry on across the shallow reef. It's not particularly large, so it's perfectly possible to work your way across it two or three times as you gradually head shallower.

Recommended Equipment
Torch

Things to See

There is quite a lot of marine life to see at Conger Alley, including quite a few species fish (particularly ballan wrasse, conger eels and lots of leopard gobies) though you often need to get right down to the seabed and look under the rocks to see them. Sealochs anemones cover virtually every boulder surface and there are also a few sponges and the occasional plumose anemone as well as all the usual velvet swimmer, harbour, hermit and some large edible crabs. Cerianthids and green crabs are common over the sand.

Conger eels are usually spotted hiding well under the boulders. They can sometimes be coaxed a little way out by waving your torch in front of (not at) them, but keep your fingers to yourself!

Sealochs anemones are virtually everywhere! You'll start seeing them the closer you get to the reef. 

There's a lot of weed to plough through in the shallows if you miss the exit!

How to: Compose a Great Wildlife Photograph

In this guide I want to consider some of the artistic elements of composition that go together in creating an outstanding photograph, and which will hopefully be of some use in your own photography. After all, your photos can be as technically perfect as you like, but if you can't create an interesting composition then you'll never have anything worth framing for your wall, selling to customers or winning awards.

As always, please click on each image to view them at full size.

Looking for more specifics? Check out my guides on "How to Photograph Birds in Flight and How to Take Photographs at Sea.

1. What is your subject?
This image of a diver inside a shipwreck provides not only the atmosphere of a dark wreck at depth, but also the abundance of life that utilise man-made structures underwater. 

You do have a subject, don't you? The subject of your photograph is essentially the part of the image that you want your viewers to focus on the most and which you want to tell them something about. There may be other elements in the image that add context or extra information, but they should never overwhelm the image to the point that the subject gets lost.

Think about what message you want to convey. Are you trying to tell a particular story? For example, is the subject exploited in some way? Do you want to show a particular behaviour? Do you want to show the animal in its habitat? Do you want the image to feel dynamic or still? Exciting or peaceful? How important is the environment around the subject? How are you going to grab the viewer's attention and keep it where you want it to be?

This shot is of a guillemot landing, but the other birds provide the context for the shot by showing that the bird is at a crowded breeding colony.

These shags in the rain show the importance of the habitat to the coastal birds.

How you answer those questions will have a direct bearing on how you will want to compose your image. Since this is something that for the most part has to be done in-camera when you take the shot, and not afterwards in post-processing, it is worth considering the kind of shots you want to come home with before you leave home.

Fortunately, there are a few tips and tricks which should help you go from taking snapshots to creating works of art, and I'd like to spend the rest of this article discussing some of the ones that are particularly relevant to wildlife and nature photography.

2. Choose your angle of view

Looking up to the gulls and maintaining eye contact makes them appear more intimidating than by shooting them from above or at eye-level.

The angle from which you shoot your image can be far more important than you might think as you can use it to define the fundamental relationship between the photographic subject and the viewer. We use phrases every day like 'looking up to' or 'looking down on' a person we respect or devalue respectively, and the same principles apply in photography. If you shoot downwards on your subject, you are putting the viewer in a position of dominance over it and diminishing the status of the subject; shooting upwards by contrast elevates the subject to the dominant position over the viewer. Both angles can be extremely effective and drastically alter the dynamic of the image. Most often however, wildlife photographers will aim to shoot at eye level with the subject, as this angle balances the relationship and puts the animal subject on an equal footing with the viewer. Since wildlife photography is often about sharing an intimate glimpse into the life of an animal, creating this sense of equality can be enormously powerful in creating a connection with the viewer, particularly where you have eye contact with the subject (but we'll come back to eyes a little later) and can get close to it.

TOP: Shooting upwards at my dog elevates him above the viewer and gives him an air of respectability he struggles to achieve in real life. MIDDLE: Shooting at eye level brings the viewer right into the action. BOTTOM: Shooting down on my dog elevates the viewer and gives the impression that we (in the dog's eyes at least) are in charge.

However, it's also worth considering how you can use your angle of view to create an interesting or novel perspective on the subject. As human beings, we see the world from about 1.5m above the ground. We are used to looking up at birds flying above us and looking down on a fish in a pond for example. Changing that perspective so we are either at eye-level with the subject or looking at it differently (e.g. looking down on a bird in flight or upwards at the fish) can create much more interesting and unusual images that will grab attention.

When was the last time you were eye to eye with a fish? Shooting from unusual angles can make your images that much more interesting.

Getting the angle you want might involve crawling on your belly through the mud to shoot upwards at your subject, or climbing a tree to shoot downwards at it, but the important thing is to think about it before you take the shot. Remember is that you're unlikely to arrive at a site and immediately happen to be standing at the best possible angle to capture your subject, so move around and experiment.

3. Positioning the subject in the frame

i. Rule of Thirds
Probably the most common composition rule that you hear about is the so-called 'rule of thirds'. I'm sure most of you will be familiar with it already, but it's essentially a simplification of the 'golden ratio' which was defined by the ancient Greeks which states that designs are more aesthetically pleasing if they are divided according to a ratio of 1 : 1.618 (approximately 3/8ths : 5/8ths, simplified to 1/3rd : 2/3rds). To apply the rule in photography, we take our image and divide it vertically and horizontally into thirds:

In this image, the plovers and their reflections align pretty well to the horizontal thirds of the image. By placing two birds and their reflections on the intersect points, we strengthen the composition even further.

According to the rule, if we place the subject (or other point of interest) onto one of those lines, we will achieve a more pleasing composition than if we place the subject more centrally in the frame or further towards the edges, with the strongest compositions being those where the subject (or point of interest) occurs at one of the four intersecting points.

There are plenty of situations where this rule doesn't apply of course, but it's a good one to start with. One of the things that new photographers often do is place the subject (or horizon if it's a landscape) centrally in the frame, which doesn't usually create a particularly interesting image, so simply remembering to offset the subject horizontally or vertically can very quickly improve your images and is easy to play around with by trying different crops in post-processing.

ii. Symmetry
So after just saying how boring images can be when the subject is placed centrally, there is an important exception, and this is where you have strong symmetry in a photograph. In these cases, offsetting your subject according to the rule of thirds would leave the image feeling unbalanced compared to a perfectly central alignment:

In images with strong symmetry, applying the rule of thirds will result in an unbalanced image so we place the subject as centrally as possible. However, the eyes still align with the upper vertical third of the image.

It is worth noting in the example above though that even though the image is central on the horizontal axis, the major points of interest, the eyes, still align vertically more or less according to the rule of thirds.

iii. Diagonals
One of the interesting things about the human brain is how much it likes diagonal lines and this can be a useful trick to exploit from time to time. For people who read left to right and top to bottom, the strongest diagonal line is the one which runs from bottom left to top right.

Diagonals often work very well with underwater subjects where we rarely expect straight lines.

Of course, this doesn't usually work so well for things that we expect to be horizontal or vertical (which is why squint horizons are so distracting in landscape images), but can be put to great use in situations where we don't have that expectation, like underwater for example.

iv. Give your subject space to move
Unless you need a particularly tight crop of your subject for some purpose (e.g. for an ID guide, or a portrait shot etc.), you can often get a better composition by giving the subject space to 'move' within the frame rather than trapping it inside a tight crop. Where you leave the space has important effects on how your image will feel to the viewer.

The top image feels more tense as there is empty space behind the bird, but nowhere for it to move to. The lower image by comparison gives more of a sense of expectation. 

Generally, if you give the subject a bit of negative space in front of it (either in the direction of travel if it's moving, or the direction in which it's facing or looking) you'll create a sense of expectation in the image, by giving the subject space to move forwards. If you place the negative space behind the subject though, you can create a feeling of tension in the image since the expectation is for something to fill the space behind the subject. The hint of an unknown threat can add an extra dynamic to your image.

3. Pay attention to the background
When you're busy focusing on taking the perfect shot of your subject, it can be incredibly easy to forget about the background, but it is nonetheless one of the most important parts of your composition by creating context for your subject or negative (empty) space around it, allowing it to stand out.

Distracting backgrounds will prevent the viewer from focusing on the important parts of the image by constantly pulling their attention away from the subject.

Generally, an uncluttered, simple background works best which you can achieve by shooting against a uniform background or by using a wide aperture to throw the background out of focus (bokeh). In the example above, the blue-green chromis on the left blend into the background, which contains lots of distracting dark patches and keeps dragging our attention away from the fish. The image on the right not keeps the background simple and allows us to look at the fish without having our eyes constantly pulled away.

4. Anchor Points
As your eye moves around photograph, it will (hopefully!) eventually settle onto an anchor point within the image (assuming the eye hasn't been led out of the frame and there aren't too many distracting elements). The anchor point should be the thing that we want the viewer to be drawn to and spend most of their time looking at, so it's important to understand a few of the properties that make a strong anchor point so you can create a powerful image that doesn't simply distract the viewer and draw attention elsewhere. Funnily enough, it turns out that our brains like looking at bright, shiny things!

The main things that tend to draw and anchor the eye are areas of:

i. Brightness
In this photograph, the bright reflection on the snorkeller's head draws the eye due to the contrast with the darkness of the rest of the image.

A flash of brightness somewhere in the image grabs our attention and pulls our gaze over to it. Watch out if you're shooting on bright days, or using a flash around reflective surfaces since you can end up with a sparkly, confusing image!

ii. Colour
The bright yellow of the gull's feet and bill immediately grab the viewer's attention and bring the focus to the bird's face and eyes, which is exactly where we want it to be.
A little splash of a contrasting or complementary colour can go a long way to drawing the eye. Yellows and reds are common warning colours in nature and we are naturally drawn to even small patches of them. While you might not be able to change the natural colours of your subject, you can often choose the setting to enhance or subdue them to achieve the effect you want.

iii. Sharpness
The sharpness of the Aristotle's Lantern in the mouth of the urchin draw the eye by being sharper than the rest of the animal. 

Finally, our eyes also focus naturally on the things we look at, bringing them into sharp relief and throwing peripheral areas out of focus. When we look at a photograph, the focal point has already been determined by the photographer for us, and so our eyes are drawn to that area of sharpness. Sharpness can only be properly achieved by getting your focus right in-camera when you take the shot, to make sure your focal point is absolutely accurate to get the best results. That means that if you want the subject's eye to be sharp, you set your focus on the eye. Not the face, the eye.

Eyes: A special case

A Japanese macaque relaxing while being groomed (Edinburgh Zoo). 

A final, and particularly important anchor point in wildlife or portrait photography are the eyes. Our brains love to look at eyes and will be naturally drawn to anything that looks like one, so some of the most striking photographs are those in which all the elements of the composition draw the viewer in to anchor on the subject's piercing gaze. If that eye is a contrasting colour to the rest of the image, perfectly sharp and bright (usually highlighted with a 'catchlight') then so much the better.

5. Leading Lines
Leading lines are simply the lines within the frame that lead the eye through an image before it (hopefully) settles onto an 'anchor point'. If used correctly, these lines should keep the eye within the frame and draw it to the main point of interest in your shot (either the subject or an interesting part of the subject, for example its eye, or perspective lines which draw the eye right into the image).

The two leading lines in this image draw the eye to the subject (the urchin).

In the photograph of the diver and the urchin, there are two main leading lines - the first is the diagonal line of stone leading us up to the urchin and the second is the beam of light provided by the diver on the left. Even though the torch itself is the brightest point in the image, the two leading lines form an arrow which point us to the true subject of the shot.

Many leading lines arise naturally through the shape of the animal itself and all the photographer has to do is frame the subject well and avoid adding distractions.

With closer-shot portrait shots, you probably don't need to worry too much about setting up the leading lines yourself as the limbs of the animal tend to lead back to the head and face normally anyway. If you're shooting an animal without these obvious features though (e.g. many invertebrates or whales & dolphins) it's worth considering how best to frame the shot beforehand.

If you have lots of lines leading in lots of different directions through your image, the eye gets drawn off in lots of different directions (or worse, out of the frame entirely) and is never allowed to settle on the real point of interest you are trying to share with the viewer. Usually, if your background is described as 'distracting' it's due to the presence of leading lines which keep pulling the eye away from the subject.

The direction of leading lines can also have an effect on the mood of the image. If you predominantly have horizontal lines running through your image then it tends to produce a sense of calm within the shot, whereas vertical lines are more dynamic and can create more of a sense of tension.

Eyes: That special case again
Leading lines don't always have to be actual lines in your image and in fact one of the most powerful leading lines you can make use of are eye-lines. Psychologically speaking, our brains are programmed to home in on eyes more than anything else, and we will follow the gaze of a person or animal to see what they are looking at. So, if your subject is looking elsewhere in the frame, the viewer's eye will follow that gaze to wherever it leads. Hopefully it's looking at something interesting and doesn't just draw us out of the frame!

This image works because the eyelines of the birds hold our view in the important part of the shot.

In the above example, the image works because even though the adult gannet's gaze is not directly leading back to the chick's eye, its eyeline is still intercepted by the chick's beak which draws us to its eye. Following the chick's eyeline, we then arrive back at the parent's eye ready to follow the loop around again. Even though our eye doesn't really settle, our focus is held in the important part of the image.

This image fails because the fish's eyeline leads us straight out the frame.

By contrast, the grey moray image fails because (besides not being a very good photo in the first place), the subject is looking to the bottom left of the image. Because there's nothing there to catch our gaze as we follow the eyeline, we end up being led straight out of the frame, which is no good at all.

7. Bring it all together
If you've got this far, congratulations! As you've probably realised by now, none of these 'rules' are particularly useful on their own and need to be brought together in order to create truly stunning images. If you can bring all the above elements together into a single image, then you're probably looking at something very special!

8. Examine other images to see what works and why
Finally, if you're struggling for inspiration or want to get some new ideas on different ways to shoot, it is always worth checking out the winners galleries for the big photographic competitions, like some of these:
