Photography Step By Step

I will conclude this first beginner tutorial with some basic ideas that you need to have in mind when taking photos, so that you will be satisfied with the final result.

What goes through your mind in the moments as you raise your digital camera up to take a shot and before you press the shutter? If you’re like many digital photographers you’re not thinking about too much – you just want to capture the moment and then move on. However getting in the habit of asking some simple questions can help take your images to the next level. Here are some questions to get in the habit of asking while framing your shots.

What story am I telling? – This is an important question and one that should help you to make any number of decisions in terms of composition, framing, exposure etc. In essence what you’re asking is “why am I taking this shot? What is it’s purpose and what am I trying to convey?” Is it purely a way to keep a record of a moment, are you trying to capture the emotion of a moment, is it possibly a shot to give to someone, is it part of a larger series of shots or will it be the only shot to commemorate the moment etc.
What is the visual focal point of this shot? – What will viewers of this picture naturally have their eye drawn to in this scene? Once you’ve identified this focal point you can think about where to place it in the frame (consider the rule of thirds for example).
What competing focal points are there? – Once you’ve identified what you do want your viewers eyes to be drawn towards and have placed it in the frame – scan your eyes over the shot and see if there are any competing focal points and ask yourself whether they add to or take away from the image? Secondary focal points can add depth to shots but they can also be very distracting and so you might need to reposition yourself or adjust your focal length and/or depth of field to accommodate or remove them from your shots. Also keep in mind that if your shot has more than one focal point that it might be worth taking two shots, one of each focal point, in order to keep things simple.
What is in the background and foreground? – One of most common places for distractions in digital photography is the background of your shots. Run your eyes over the space behind your subject to see what else is in the image (do the same for the foreground). Consider whether you want the background in focus or nice and blurry.
Am I close enough? – Another common mistake in digital photography is taking shots where your subject is too small in the frame. Shots that fill the frame with your subject tend to be much more dynamic and show a lot more detail of your subject. To get this effect you have the option of moving yourself closer, moving your subject closer or using a longer focal length to give the effect of closeness.
What is the main source of light? – Always give consideration to how your subject is lit. Without light you’ll lose detail and clarity in your image and your camera will have to compensate by doing things like increasing ISO and lengthening shutter speeds (which could lead to noisy and blurred images). What is the main source of light, where is it coming from, is there enough light, do you need artificial light sources (flash etc), do you need to stabilize your camera on a tripod to stop camera shake due to low light etc.
Is my Framing Straight? – It’s amazing how many otherwise good photos are spoiled by framing that is slightly offline. Sloping horizons and slightly leaning people or buildings should always be in the back of your mind to check.
What other perspectives could I capture this subject from? – Put 10 digital camera owners in front of a scene and most of them will take exactly the same shot from the same position. Make your images stand out from the crowd by challenging yourself to not only take the standard shots that everyone else will get but to find creative and fresh angles and perspectives to shoot from.
How would holding the camera in the other format change this shot? – Many photographers get into the habit of always holding their camera the same way (horizontally/landscape or vertically/portrait). While it’s OK to have a preference one way or the other it’s also worth remembering that changing the format can drastically change the impact of the shot. Don’t forget you can also hold your camera at an angle for an effective result too.
How will the eye travel through this image? – This is related to asking about focal points but gets in touch with the fact that while you’re photographing a still image your viewers eyes don’t remain still as they look at an image. People tend to follow lines and are attracted to shapes and colors so considering all of these different visual elements and cues can help improve your shots considerably.

Of course you probably won’t remember all the questions and you’re unlikely to go through each of them with every shot you take – however next time you head out with your digital camera concentrate on asking yourself at least one or two of them as you take your shots. As you do you’ll find that they become more automatic and in time you’ll naturally take digital photography shots that take into account all of these elements.

APERTURE PRIORITY MODE (A or AV): This mode is really a semi-automatic (or semi-manual) mode where you choose the aperture and the camera chooses the shutter speed so as to ensure you have a well balanced exposure. Aperture priority mode is useful when you’re looking to control the depth of field in a shot (usually a stationary object where you don’t need to control shutter speed). Choosing a larger number aperture means the aperture is smaller and lets less light in. This means you’ll have a larger depth of field (more of the scene will be in focus) but that your camera will choose a slower shutter speed. Small numbers means the opposite (if your aperture is large, depth of field will be small and your camera will probably choose a faster shutter speed).

SHUTTER PRIORITY MODE (S or TV): Shutter priority is very similar to aperture priority mode but is the mode where you select a shutter speed and the camera then chooses the aperture. You would use this mode where you want to control over shutter speed (obviously). For example when photographing moving subjects (like sports) you might want to choose a fast shutter speed to freeze the motion. On the flip-side of this you might want to capture the movement as a blur of a subject like a waterfall and choose a slow shutter speed. You might also choose a slow shutter speed in lower light situations.

PROGRAM MODE (P): Some digital cameras have this priority mode in addition to auto mode. In those cameras that have both, Program mode is similar to Auto but gives you a little more control over some other features including flash, white balance, ISO etc. Check your digital camera’s manual for how the Program mode differs from Automatic in your particular model.

MANUAL MODE (M): In this mode you have full control over your camera and need to think about all settings including shutter speed, aperture, ISO, white balance, flash etc. It gives you the flexibility to set your shots up as you wish. Of course you also need to have some idea of what you’re doing in manual mode so most digital camera owners tend to stick to one of the priority modes.

I’ve decided to talk about Exposure Time and Aperture in the same lesson because it is a strong relation between them, which I’ll explain later. First I will discuss about each of them to help you understand them better.

EXPOSURE TIME: The Exposure Time is the period of time in which the sensor will be exposed to light. This is done in the moment push the button to take the picture. A mechanism inside the camera will open for the precise amount of time that has been manually set or automatically calculated by the camera. The exposer time on a digital camera can vary in a wide range. For example, on my Canon 450D DSLR the exposure time interval is from 1/4000 to 30. That means that I can expose the sensor from the tiny amount of time that is 1/4000 of a second up to 30 seconds. This is set accordingly to light conditions where the picture is taken.

APERTURE: This is a little more complicated to understand than exposer time, but I’ll try to explain it as simple as I can. The aperture is a characteristic of lenses and it is usually specified on these as a value like 1:3.5-5.6 (on lenses with zoom capability) or 1:1.8 (on lenses with no zoom). To make an analogy with the human eye, aperture is similar to the pupil. It gives us the ability to set the amount  of light that enters through the lens by closing or opening a mechanism similar to the eye pupil. A smaller number means a wider opening so more light will come in. The numbers specified on lenses means the maximum opening of the aperture that can be achieved. For example a value like 1:3.5-5.6 (or f/3.5-f/5.6) on some zoom lenses means that we can get a maximum aperture opening of 1:3.5 (or f/3.5) on no zoom and a 1:5.6  (or f/5.6) one on maximum zoom.
Another very important aspect about aperture is the Depth Of Field (or DOF). Depth of field is a term which refers to the areas of the photograph both in front and behind the main focus point which remain “sharp” (in focus). Depth of field is affected by the aperture. A larger aperture (smaller f-number, e.g. f/2) has a shallow depth of field. Anything behind or in front of the main focus point (the main point that you want to be sharp) will appear blurred. A smaller aperture (larger f-number, e.g. f/11) has a greater depth of field. Objects within a certain range behind or in front of the main focus point will also appear sharp. Here is an example:

The relationship between aperture and exposure time is that a smaller aperture will result in less light that will enter through lenses, so a longer exposure time will be required and vice versa. So you can achieve the same luminosity in a picture using different aperture/exposure time combination. The main reason for playing with these two is again the DOF (Depth of Field). There are many situations when you want a shallow DOF (so a blurred background), like in portraits, macros, etc, and there are situations when you’ll prefer a greater DOF, for example in landscape photography. To master this two in combination will require time and a lot of exercises, but I assure you that it worth the effort.
