Digital SLR Camera Controls on the Back
Because you can do so many different things with a dSLR camera, the learning curve is a bit steep. You’re a more serious photographer, though, so those options are probably the reason you bought a digital SLR in the first place — even if you might find all those controls daunting at first. This list will help you get your dSLR controls under control:
Autofocus lock: Lock the focus zone at its current setting so that you don’t accidentally switch to another focus zone while shooting.
Cursor movement pad: A four-way cursor control pad that you can use to navigate menus and move indicators (such as focus zones) in your viewfinder.
Delete Photo: Press to delete the current photo.
Information: Change the status information display.
Jump: Advance to the next group of photos during review or to the next menu screen.
LCD screen: Use this screen to review your photos after you take them and to view menu options.
Main command dial: Spin this dial to adjust the main settings, such as exposure value (EV) or shutter speed.
Memory card access lamp: This lamp, usually green or red, illuminates when the camera is writing to the memory card.
Memory card door: The cover over the SD or CompactFlash slot.
Menu: Press to navigate your camera’s setup, picture-taking, and playback menu options by using the multi-selector or cursor movement pad to move the menu cursor.
On/Off switch: Flip your dSLR on or off. Typical cameras sip juice judiciously, so you might not need to turn off your camera until you finish a shooting session.
Playback: Press to activate picture review.
Print/share: Mark the displayed image for printing.
Zoom in/zoom out: Magnify and de-magnify the image during picture review.
