Test Yourself: How Many of These 10 Things Do You Already Know?

DSLRs (and system cameras like the Micro Four Thirds range) are packed to the gunnels with features and functions. Fortunately, it’s not necessary to use each and every one whenever you pick up your camera (I’ll let you into a little secret, there are features on my camera that I’ve used so infrequently that they’re got metaphorical cobwebs growing on them). However, it’s useful to know that they’re there and what they do. You never know when you may need them…Here’s ten that it’s worth being familiar with.

Custom white balance

Auto white balance is all very well but it occasionally gets things wrong. Creating a custom white balance for a particular shooting situation is far more accurate.

Positive exposure compensation is often necessary when shooting snow scenes.

Exposure compensation

You camera meter’s not infallible either. Being able to step in and override the exposure is invaluable, particularly when shooting scenes that are above or below average reflectivity (snow scenes for instance).

The depth of field preview button is very useful when shooting landscape that require front-to-back sharpness.

Depth of field preview button

Typically when you look through the viewfinder you see the scene with the lens aperture wide open (regardless of the aperture you’ve set). This means that depth of field is at its minimum, making it hard to judge what will be sharp or unsharp in the image. Holding down the depth of field preview button temporarily closes the aperture to the set value. This will make the viewfinder darker but enables you to see the extent of depth of field. Depth of field preview often works in Live View too.

Focus confirmation

Different cameras have different ways to confirm focus. Most beep and also light a focus confirmation symbol either in the viewfinder or on the LCD. What’s even more useful is when the camera illuminates the focus point at which focus is determined. This makes it easy to judge whether focus is in the right place or not. Which leads on to…

If your subject is off-centre, move the AF point over the subject to ensure that your camera focuses correctly.

Selecting the focus point

A camera doesn’t know where you want to focus. In auto focus point selection it often just settles on the nearest object to the camera. Switching to manual AF point selection will allow you to decide which focus point is used to focus. It’s a useful feature if your subject is behind something else or is off-centre.

Shooting modes

The shooting mode you choose determines how much control you have over the shooting process. Modes such as Portrait or Landscape are great for specific shooting situations but you do get locked out of making useful adjustments (such as custom white balance). Modes such as Aperture Priority and Manual give you more control, with the downside that it’s easier to make more mistakes.

Favourite menu options

It can be a chore wading through menus to find the function that you want. Most cameras have a facility to save menu options to a custom menu (frequently called My Menu). Saving your favourite or most used menu options is a useful time saver.

Auto ISO is a useful function if you’re without tripod and are spending the day swapping between scenes with radically different light levels.

Auto ISO

If you handhold your camera Auto ISO is invaluable for maintaining a shutter speed that’s fast enough to avoid camera shake. The downside is the potential for increased image noise, but that’s a small price to pay for sharp photos.

Spot metering is invaluable if your subject is spot-lit – evaluative metering may get fooled by the large areas of black around the subject.

Metering modes

Most cameras default to evaluative (or matrix) metering. For most shooting situations this is perfectly accurate. What’s more accurate, particularly if you want to meter from a small area of a scene, is spot metering. This is especially useful for accurate metering of subjects that are spot-lit.

AE Lock

Occasionally there’s a need to meter a scene and then recompose (such as when using spot metering). Pressing the AE Lock button locks the exposure at the metered value. You can then recompose without the exposure altering. It won’t unlock until you either unlock the exposure again, take the shot at the locked exposure value or the camera automatically powers down after a few minutes’ inactivity.

  1. Hey! I know this is kind of off topic but I was wondering
    which blog platform are you using for this website?
    I’m getting tired of WordPress because I’ve had issues with hackers and I’m looking at
    options for another platform. I would be awesome if you could point me in the direction of a good platform.
