How well do you know your camera? Do you know everything that it’s capable of? It’s certainly possible you know your camera like the back of your hand, in which case you should be commended. Good job.
But there are those who have to admit some degree of feature ignorance. It’s not totally your fault; today’s digital cameras are bursting at the seams with so many bells and whistles and many photographers just aren’t going to go exploring the murky depths of their camera’s menu system looking for some feature they may or may not use regularly. This is a simple matter of functional pragmatism — as long as your camera does what you need it to do (and does it well), you’re content. It’s a philosophy I wholeheartedly subscribe to.
But there’s also great value in exploration. Go poking around your camera’s menus and you’re sure to find some useful feature that you didn’t previously know was there or hadn’t ever given much thought to. Sure, some features are nothing more than gimmicks; but there are some little used features that could be just the thing you need in a challenging situation, or to achieve a desired effect, or to simply make your life a little bit easier. You won’t use them every time you pick up your camera, but you’ll have the peace of mind of knowing they’re there when you want or need them.
Here are 6 “hidden” camera features you will be glad to discover.
1. Back Button Focus
If you learned to use your DSLR in standard fashion, then you’ve mastered the process of pressing the shutter button halfway to initiate autofocus and pressing it fully to take the shot. It works well enough and I’ve never heard anyone complain about the process. But there’s another way — perhaps a better way.
With back button focus, you take away the task of focusing from the shutter button and assign it to a button on the rear of your camera, typically the AF-ON/AF-L button or * button.
The advantages of back button focus include reducing (or eliminating) the need to switch your lens to manual focus, easily maintaining continuous focus, and improved stability as you don’t need to half-press anything. You use your thumb to engage and maintain focus while using your index finger to fire off a shot. It may sound unimpressive and it takes some getting used to, but once you become accustomed to back button focus you might never return to the old way.
While not all cameras have a dedicated AF button, virtually any DSLR can be customized to use back button focus. Have a look at this tutorial to learn more about back button focus and how to set it up on your camera.
2. In-Camera HDR
Roaring debates about the aesthetic qualities of HDR are pointless — you either like it or you don’t. If you don’t, then don’t bother making HDR images. If you do, and you’ve got a relatively recent model DSLR (such as Nikon’s D800 and D600 or Canon’s 5D Mark 3 and 6D), then you’ve got a built-in HDR feature that could certainly come through in a pinch or give you a way to experiment with the look. In-camera HDR won’t do a better job (at least not yet) than post-processing software, but having the capability right at your at your fingertips at all times could prove useful some photographers.
3. Image Ratings
If you're one who regularly applies ratings (on a 5-star scale, for example) to your images, you should be excited to know that you don't have to wait until you transfer your images to Lightroom or whatever software you use to rate your shots; you can do this in-camera. Additionally, the rating you apply in-camera is retained and used by your post processing software, so you don't have to go through the rating process twice.
Why rate your images in the first place? Different people have different reasons; it could be part of a custom organization scheme or the first layer in a self-critiquing process, or you could allow clients to have a look at the images and rate their favorites. No matter the specifics, you'll probably enjoy the utility of in-camera ratings.
4. Mirror Lock Up
Much to my surprise, I've encountered what I consider to be an inordinate number of DSLR owners that don't realize their camera has a mirror lock up feature. 35mm film cameras commonly made this feature available via a switch of some kind located on the camera body; the feature is still available in the digital age, but you'll have to go into your camera's menu to activate it. If you desire an additional measure of stability (to avoid camera shake) then you probably won't mind taking a trip through a few menu levels.
5. Double Exposures
Another sort of film camera “throwback” feature is the ability to do in-camera double exposures. Allowing the photographer to expose two images on one frame, the double exposure feature is more commonly found in point-and-shoot cameras as opposed to DSLRs (my Lumix LX7 has this ability but neither of my Canon DSLRs do), but there are a few DSLRs that sport in-camera double exposures (a number of Pentax and Olympus models, a few Nikon models, and only a couple of Canon models). Much like in-camera HDR, you might be better served doing double exposures in Photoshop or similar software — or not. The ability to do them in-camera lets you experiment on the fly, and if you embrace the element of surprise, then you’re likely to love this method.
6. Picture Styles
If you shoot JPEGs, you can use pictures styles (or picture controls) to fine tune the aesthetic qualities of your final image by adjusting attributes such as contrast, saturation, sharpness, etc. Most cameras will first present you with several presets — portrait, landscape, or monochrome, for instance — but if you dig a little deeper into the menu you’ll find options that allow you to set each attribute however you want and even save your settings as a custom preset. While raw files still have the upper hand in terms of flexibility, using picture styles will give you as much control as possible over your straight-out-of-camera JPEGs.
The list of little known and little used camera features could grow rather long; there are numerous features patiently waiting in their respective menus to be discovered by enterprising and curious photographers. The main purpose of this write-up is to encourage you to explore your camera, get to know it more in depth, and take full advantage of any features that might make your photography more fun, more convenient, more efficient, and more fulfilling.
