Mastering Your Camera

There are only 12 skills you need to learn to master your camera. Check out what they are.

I’m not the only one that contends that mastering your camera is an important first step in mastering photography. You’ll see it in blog posts, articles and videos.

Let’s take a deeper, more detailed look at what it means to master your camera and show that it’s not an impossible task, as intimidating as it may seem when you first start.

It starts with the question, “What does a camera do?” The hundreds of pages in the camera’s user manual and a similar number of options in its menus make it look like mastering it is a massive if not impossible task.  It appears daunting, especially if you are not technically inclined.  But in reality, what you need the camera to do comes down to just two things – control the exposure and control sharpness. Let’s see what core skills are required to master these two things.

Control Exposure

The purpose of exposure control is to ensure the right amount of light enters the camera so that the sensor can record the image you are photographing.  You and the camera need to respond to both bright and dark scenes.  The exposure controls are what makes it possible to match the exposure to the kinds of lighting conditions you encounter.

There are three variables that can be adjusted to respond to the amount of light in the scene – ISO, aperture and shutter speed. These three variables form the famous exposure triangle.

Tell Me More About Auto Exposure Bracketing

Review the history of auto exposure bracketing and how it is used in the digital age.

What Is Auto Exposure Bracketing and What Is It Used For?

Auto Exposure Bracketing (or AEB) dates back to the film days. Color reversal film, or slide film, was very sensitive to exposure. If your exposure was off by even a half a stop, it would not be acceptable for critical work. So, photographers got into the habit of taking three shots – one at the exposure they calculated, one a half stop overexposed and one a half stop underexposed. This ensured that one of the frames was correctly exposed.

In the digital world, AEB plays a different role. With the power of the tools available to us in the digital darkroom, we can easily compensate for exposures that are not perfect.

But now we can photograph scenes that were not possible in the film days. These are scenes in which the dynamic range exceeds the ability of the sensor (or film) to capture. In the film days you could use a graduated neutral density (grad ND) filter if there was a clear and straight dividing line between the bright and dark parts of the image. But for scenes where no such line existed, such as dappled sunlight on a forest floor, you had to forego the photograph.

In the digital world you have the ability to capture scenes with even the most difficult dynamic range challenges. The technique is HDR and it involves taking multiple shots with enough different exposures to capture the full dynamic range and blending them together in the digital darkroom.

And this is where AEB comes in. Instead of a bracketing interval of 1/5 stop, you can set a bracketing interval of 1 stop, 2 and even more stops. The bracketing interval depends on your camera. Not all are the same. And many digital cameras will allow you to take two, three, five or even seven shots to ensure you capture the full dynamic range of the scene, again, depending on your camera.

You can use AEB by pressing the shutter once for each shot up to the number of shots you specified. Or you can put the shutter on burst mode and press and hold it until the camera takes all of the shots.

Finding the Control

Different camera manufactures have their own ways of applying auto exposure bracketing. This may even change from model to model.

Consult your camera’s manual to learn how to use it.
