Camera features on the top of your camera body
01 Built-in flash
When there’s not enough available light to capture a decent exposure, your DSLR’s built-in flash can pop-up to shine some light on the situation. In some modes, you may need to pop it up manually. If there’s not enough light for the camera’s Auto Focus to function the flash unit can also produce a burst of light to help, called an AF-assist beam.
02 Shutter button
Press this button all the way down to capture a shot. Press it half way down to focus and take an exposure reading of the scene’s lighting. Also press here to wake the camera up after it has gone into sleep mode.
03 Main Dial
Rotating this dial enables you to manually set the camera’s aperture or shutter speed. It’s called the Command dial on a Nikon.
04 ISO button
Click here to choose an ISO speed for the camera to use. You can then use the Main Dial to select a faster ISO speed to make the camera more sensitive to low light. You can also set the ISO speed manually by going through the menu system on most digital SLRs and many compacts.
05 On/off switch
Turn the camera off when not in use (though it will automatically fall asleep to save power after 30 seconds).
06 Mode Dial
Rotate this dial to choose a shooting mode. The camera will then set the appropriate aperture and shutter speed setting (as well as processing colour in different ways depending on the mode). There are Basic shooting modes for every type of subject (like Portrait or Landscape).
07 Flash hot shoe mount
All DSLRs enable you to mount a more powerful flashgun on top of the camera so that you can illuminate distant subjects (and perform more creative and effective flash-related shots).
