Lesson 3.1: Breaking rules

Photo Composition Tip 1: Simplify the scene
10 rules of photo composition (and why they work)

When you look at a scene with your naked eye, your brain quickly picks out subjects of interest. But the camera doesn’t discriminate – it captures everything in front of it, which can lead to a cluttered, messy picture with no clear focal point.
What you need to do is choose your subject, then select a focal length or camera viewpoint that makes it the centre of attention in the frame. You can’t always keep other objects out of the picture, so try to keep them in the background or make them part of the story.
Silhouettes, textures and patterns are all devices that work quite well in simple compositions.

Photo Composition Tip 2: Fill the frame

When you’re shooting a large-scale scene it can be hard to know how big your subject should be in the frame, and how much you should zoom in by. In fact, leaving too much empty space in a scene is the most widespread compositional mistake (learn how to Replace boring skies in Photoshop). It makes your subject smaller than it needs to be and can also leave viewers confused about what they’re supposed to be looking at.
To avoid these problems you should zoom in to fill the frame, or get closer to the subject in question. The first approach flattens the perspective of the shot and makes it easier to control or exclude what’s shown in the background, but physically moving closer can give you a more interesting take on things (see our list of Digital camera effects from A-Z).

Photo Composition Tip 3: Aspect ratio

It’s easy to get stuck in a rut and take every picture with the camera held horizontally. Try turning it to get a vertical shot instead, adjusting your position or the zoom setting as you experiment with the new style. You can often improve on both horizontal and vertical shots by cropping the photo later.
After all, it would be too much of a coincidence if all your real-life subjects happened to fit the proportions of your camera sensor. Try cropping to a 16:9 ratio for a widescreen effect, or to the square shape used by medium-format cameras.

Photo Composition Tip 4: Avoid the middle

When you’re just starting out, it’s tempting to put whatever you’re shooting right in the centre of the frame. However, this produces rather static, boring pictures. One of the ways to counteract this is to use the Rule of Thirds, where you split the image up into thirds, both horizontally and vertically, and try to place your subject on one of these imaginary lines or intersections. This is an overrated approach, though.
Instead, move your subject away from the centre and get a feel for how it can be balanced with everything else in the scene, including any areas of contrasting colour or light. There are no hard and fast rules about achieving this kind of visual balance, but you’ll quickly learn to rely on your instincts – trust that you’ll know when something just looks right.

Photo Composition Tip 5: Leading lines

A poorly composed photograph will leave your viewers unsure about where to look, and their attention might drift aimlessly around the scene without finding a clear focal point. However, you can use lines to control the way people’s eyes move around the picture.
Converging lines give a strong sense of perspective and three-dimensional depth, drawing you into an image. Curved lines can lead you on a journey around the frame, leading you towards the main subject.
Lines exist everywhere, in the form of walls, fences, roads, buildings and telephone wires. They can also be implied, perhaps by the direction in which an off-centre subject is looking.

Photo Composition Tip 6: Use diagonals

Horizontal lines lend a static, calm feel to a picture, while vertical ones often suggest permanence and stability. To introduce a feeling of drama, movement or uncertainty, look for diagonal lines instead.
You can need nothing more than a shift in position or focal length to get them – wider angles of view tend to introduce diagonal lines because of the increased perspective; with wide-angle lenses you’re more likely to tilt the camera up or down to get more of a scene in.
You can also introduce diagonal lines artificially, using the ‘Dutch Tilt’ technique. You simply tilt the camera as you take the shot. This can be very effective, though it doesn’t suit every shot and is best used sparingly (see our 44 essential digital camera tips and tricks).

Photo Composition Tip 7: Space to move

Even though photographs themselves are static, they can still convey a strong sense of movement. When we look at pictures, we see what’s happening and tend to look ahead – this creates a feeling of imbalance or unease if your subject has nowhere to move except out of the frame.
You don’t just get this effect with moving subjects, either. For example, when you look at a portrait you tend to follow someone’s gaze, and they need an area to look into (check out ourFree portrait photography cropping guide).
For both types of shot, then, there should always be a little more space ahead of the subject than behind it.

Photo Composition Tip 8: Backgrounds

Don’t just concentrate on your subject – look at what’s happening in the background, too. This ties in with simplifying the scene and filling the frame. You can’t usually exclude the background completely, of course, but you can control it.
You’ll often find that changing your position is enough to replace a cluttered background with one that complements your subject nicely (find out how to Fix background distractions in 3 steps). Or you can use a wide lens aperture and a longer focal length to throw the background out of focus.
It all depends on whether the background is part of the story you’re trying to tell with the photo. In the shot above, the background is something that needs to be suppressed.

Photo Composition Tip 9: Creative with colours

Bright primary colours really attract the eye, especially when they’re contrasted with a complementary hue. But there are other ways of creating colour contrasts – by including a bright splash of colour against a monochromatic background, for example. You don’t need strong colour contrasts to create striking pictures, though (find out How to conquer high contrast with auto-exposure bracketing).
Scenes consisting almost entirely of a single hue can be very effective. And those with a limited palette of harmonious shades, such as softly lit landscapes, often make great pictures.
The key is to be really selective about how you isolate and frame your subjects to exclude unwanted colours.

Photo Composition Tip 10: Breaking the rules

Photo composition is a little like a visual language – you can use it to make your pictures pass on a specific message. However, just as we sometimes use the written word to create a deliberately jarring effect, we can do the same with photos by breaking with standard composition conventions.
Doing it by accident doesn’t count, though! It’s when you understand the rules of composition and then break them on purpose that things start to get interesting. It’s often best to break one rule at time, as John Powell does in the image above.
Just remember: for every rule we suggest, somewhere out there is a great picture that proves you can disregard it and still produce a fantastic image!

Lesson 3.1: Basics to Composition


Composition is an unique idea of one photographer, hence there are some guides to make a snap more interesting, proving more info and making it striking that blows the views mind. Lets go through some traditional ideas. 

Rule of Thirds

Imagine that your image is divided into 9 equal segments by 2 vertical and 2 horizontal lines. The rule of thirds says that you should position the most important elements in your scene along these lines, or at the points where they intersect.
Doing so will add balance and interest to your photo. Some cameras even offer an option to superimpose a rule of thirds grid over the LCD screen, making it even easier to use.

Balancing Elements

Placing your main subject off-centre, as with the rule of thirds, creates a more interesting photo, but it can leave a void in the scene which can make it feel empty. You should balance the "weight" of your subject by including another object of lesser importance to fill the space.

Leading Lines

When we look at a photo our eye is naturally drawn along lines. By thinking about how you place lines in your composition, you can affect the way we view the image, pulling us into the picture, towards the subject, or on a journey "through" the scene. There are many different types of line - straight, diagonal, curvy, zigzag, radial etc - and each can be used to enhance our photo's composition.

Symmetry and Patterns

We are surrounded by symmetry and patterns, both natural and man-made., They can make for very eye-catching compositions, particularly in situations where they are not expected. Another great way to use them is to break the symmetry or pattern in some way, introducing tension and a focal point to the scene.

Texture

Images a two dimensional thing yet with the clever use of "texture" they can come alive that looks almost three dimensional. Texture particularly comes into play when the light objects at interesting angles. 


Viewpoint

Before photographing your subject, take time to think about where you will shoot it from. Our viewpoint has a massive impact on the composition of our photo, and as a result it can greatly affect the message that the shot conveys. Rather than just shooting from eye level, consider photographing from high above, down at ground level, from the side, from the back, from a long way away, from very close up, and so on.

Background

How many times have you taken what you thought would be a great shot, only to find that the final image lacks impact because the subject blends into a busy background? The human eye is excellent at distinguishing between different elements in a scene, whereas a camera has a tendency to flatten the foreground and background, and this can often ruin an otherwise great photo. Thankfully this problem is usually easy to overcome at the time of shooting - look around for a plain and unobtrusive background and compose your shot so that it doesn't distract or detract from the subject.

Depth

Because photography is a two-dimensional medium, we have to choose our composition carefully to conveys the sense of depth that was present in the actual scene. You can create depth in a photo by including objects in the foreground, middle ground and background. Another useful composition technique is overlapping, where you deliberately partially obscure one object with another. The human eye naturally recognises these layers and mentally separates them out, creating an image with more depth.

Framing

The world is full of objects which make perfect natural frames, such as trees, archways and holes. By placing these around the edge of the composition you help to isolate the main subject from the outside world. The result is a more focused image which draws your eye naturally to the main point of interest.

Cropping

Often a photo will lack impact because the main subject is so small it becomes lost among the clutter of its surroundings. By cropping tight around the subject you eliminate the background "noise", ensuring the subject gets the viewer's undivided attention.

Experimentation

With the dawn of the digital age in photography we no longer have to worry about film processing costs or running out of shots. As a result, experimenting with our photos' composition has become a real possibility; we can fire off tons of shots and delete the unwanted ones later at absolutely no extra cost. Take advantage of this fact and experiment with your composition - you never know whether an idea will work until you try it.

Digital photography allows us to experiment with different compositions until we find the perfect one. Image by Jule Berlin.

Composition in photography is far from a science, and as a result all of the "rules" above should be taken with a pinch of salt. If they don't work in your scene, ignore them; if you find a great composition that contradicts them, then go ahead and shoot it anyway. But they can often prove to be spot on, and are worth at least considering whenever you are out and about with your camera.

Lesson 2.4: Know your camera: White Balance

At its simplest – the reason we adjust white balance is to get the colors in your images as accurate as possible.
Why White Balance (WB): You might have noticed when examining shots after taking them that at times images can come out with an orange, blue, yellow etc look to them – despite the fact that to the naked eye the scene looked quite normal. The reason for this is that images different sources of light have a different ‘color’ (or temperature) to them. Fluorescent lighting adds a bluish cast to photos whereas tungsten (incandescent/bulbs) lights add a yellowish tinge to photos.
The range in different temperatures ranges from the very cool light of blue sky through to the very warm light of a candle.
We don’t generally notice this difference in temperature because our eyes adjust automatically for it. So unless the temperature of the light is very extreme a white sheet of paper will generally look white to us. However a digital camera doesn’t have the smarts to make these adjustments automatically and sometimes will need us to tell it how to treat different light.

Adjusting White Balance: Different digital cameras have different ways of adjusting white balance so ultimately you’ll need to get out your camera’s manual out to work out the specifics of how to make changes. Having said this – many digital cameras have automatic and semi-automatic modes to help you make the adjustments.

Preset White Balance Settings: Here are some of the basic White Balance settings you’ll find on cameras:



  • Auto – this is where the camera makes a best guess on a shot by shot basis. You’ll find it works in many situations but it’s worth venturing out of it for trickier lighting.
  • Tungsten – this mode is usually symbolized with a little bulb and is for shooting indoors, especially under tungsten (incandescent) lighting (such as bulb lighting). It generally cools down the colors in photos.
  • Fluorescent – this compensates for the ‘cool’ light of fluorescent light and will warm up your shots.
  • Daylight/Sunny – not all cameras have this setting because it sets things as fairly ‘normal’ white balance settings.
  • Cloudy – this setting generally warms things up a touch more than ‘daylight’ mode.
  • Flash – the flash of a camera can be quite a cool light so in Flash WB mode you’ll find it warms up your shots a touch.
  • Shade – the light in shade is generally cooler (bluer) than shooting in direct sunlight so this mode will warm things up a little.

Manual White Balance Adjustments: In most cases you can get a pretty accurate result using the above preset white balance modes – but some digital cameras (most DSLRs and higher end point and shoots) allow for manual white balance adjustments also.

The way this is used varies a little between models but in essence what you do is to tell your camera what white looks like in a shot so that it has something as a reference point for deciding how other colors should look. You can do this by buying yourself a white (or grey) card which is specifically designed for this task – or you can find some other appropriately colored object around you to do the job.





Lesson 2.3: Know your camera: Metering

Metering: Metering is how your camera determines what the correct shutter speed and aperture should be, depending on the amount of light that goes into the camera and the sensitivity of the sensor. Back in the old days of photography, cameras were not equipped with a light “meter”, which is a sensor that measures the amount and intensity of light. Photographers had to use hand-held light meters to determine the optimal exposure. Obviously, because the work was shot on film, they could not preview or see the results immediately, which is why they religiously relied on those light meters.

Today, every DSLR has an integrated light meter that automatically measures the reflected light and determines the optimal exposure. The most common metering modes in digital cameras today are:


  • ·        Multi Segmented Metering, also known as Matrix Metering for Nikon and Evaluative Metering for Canon.
  • ·        Center-weighted Metering.
  • ·        Spot Metering, also known as Partial Metering for Canon.

You can see the camera meter in action when you shoot in Manual Mode – look inside the viewfinder and you will see bars going left or right, with a zero in the middle, as illustrated below.



If you point your camera at a very bright area, the bars will go to “+” side, indicating that there is too much light for the current exposure settings. If you point your camera at a very dark area, the bars will go to the “-” side, indicating that there is not enough light. You would then play around with your Shutter speed, Aperture and ISO to get to “0″, which is the optimal exposure, according to your camera meter.

A camera meter is not only useful for just the Manual Mode – when you choose another mode such as Aperture Priority, Shutter Priority or Program Mode, the camera automatically adjusts the settings based on what it reads from the meter.


  • Multi Segmented Metering: This mode is the default metering mode on most DSLRs. It works similarly to the above example by dividing the entire frame into multiple “zones”, which are then all analyzed on individual basis for light and dark tones. One of the key factors (in addition to color, distance, subjects, highlights, etc) that affect multi segmented metering, is where the camera focus point is set to. After reading information from all individual zones, the metering system looks at where you focused within the frame and marks it more important than all other zones. There are many other variables used in the equation, which differ from manufacturer to manufacturer. Nikon, for example, also compares image data to a database of thousands of pictures for exposure calculation.



You should use this mode for most of your photography, since it will generally do a pretty good job in determining the correct exposure. I leave my camera metering mode on matrix metering for most of my photography needs, including landscape and portrait photography.


  • Center-weighted Metering: Using the whole frame for determining the correct exposure is not always desirable. What if you are trying to take a headshot of a person with the sun behind? This is where center-weighted metering comes in handy. Center-weighted Metering evaluates the light in the middle of the frame and its surroundings and ignores the corners. Compared to Matrix Metering, Center-weighted Metering does not look at the focus point you select and only evaluates the middle area of the image.



Use this mode when you want the camera to prioritize the middle of the frame, which works great for close-up portraits and relatively large subjects that are in the middle of the frame. For example, if you were taking a headshot of a person with the sun behind him/her, then this mode would expose the face of the person correctly, even though everything else would probably get heavily overexposed.


  • Spot Metering: Spot Metering only evaluates the light around your focus point and ignores everything else. It evaluates a single zone/cell and calculates exposure based on that single area, nothing else. I personally use this mode a lot for my bird photography, because the birds mostly occupy a small area of the frame and I need to make sure that I expose them properly, whether the background is bright or dark. Because the light is evaluated where I place my focus point, I could get an accurate exposure on the bird even when the bird is in the corner of the frame. Also, if you were taking a picture of a person with the sun behind but they occupied a small part of the frame, it is best to use the spot metering mode instead. When your subjects do not take much of the space, using Matrix or Center-weighted metering modes would most likely result in a silhouette, if the subject was back-lit. Spot metering works great for back-lit subjects like that.



Another good example of using spot metering is when photographing the Moon. Because the moon would take up a small portion of the frame and the sky is completely dark around it, it is best to use Spot metering – that way, we are only looking at the light level coming from the moon and nothing else.

Some DSLRs like the Canon 1D/1Ds are capable of multi-spot metering, which basically allows choosing multiple spots to measure light and come up with an average value for a good exposure.

How to change camera metering mode: Unfortunately, this varies not only from manufacturer to manufacturer, but also from model to model. On Beginner level DSLRs, it is done through the menu setting, while on advanced bodies, like Alpha 700, there is a dedicated button to the right side of the viewfinder.

Metering modes on Professional DSLRs


Problems with Metering: Camera meters work great when the scene is lit evenly. However, it gets problematic and challenging for light meters to determine the exposure, when there are objects with different light levels and intensities. For example, if you are taking a picture of the blue sky with no clouds or sun in the frame, the image will be correctly exposed, because there is just one light level to deal with. The job gets a little harder if you add a few clouds into the image – the meter now needs to evaluate the brightness of the clouds versus the brightness of the sky and try to determine the optimal exposure. As a result, the camera meter might brighten up the sky a little bit in order to properly expose the white clouds – otherwise, the clouds would look too white or “overexposed”.
What would happen if you added a big mountain into the scene? Now the camera meter would see that there is a large object that is much darker (relative to the clouds and the sky), and it would try to come up with something in the middle, so that the mountain is properly exposed as well. By default, the camera meter looks at the light levels in the entire frame and tries to come up with an exposure that balances the bright and the dark areas of the image.
