Canon DSLR Tips 42-49
42 Mirror Lock-up
Found in the Custom Functions, the Mirror Lock-up makes long, low-light tripod shots even sharper. It ensures the mirror is raised up well before the exposure starts, thereby minimising even tiny vibrations.
Like Mirror Lock-up, this Custom Function is very useful for cutting out camera vibration when taking long exposures with a tripod. If you use Self-timer and Mirror Lock-up together, the delay is automatically reduced to two seconds.
Did you know your EOS camera will play back all the pictures on your card as an automated slideshow? Find the Auto Play option in your camera's menu, then press Set. It's even more fun when you connect the camera to your TV with the lead that came in your EOS box.
45 Auto Lighting Optimiser
A useful exposure adjustment Custom Function found on newer models, this widget will automatically adjust the contrast of the image and rescue shadow detail. It's particularly good at making low-contrast scenes look more punchy. The Auto Lighting Optimiser can also lighten up faces in backlit portraits, and detect when flash-lit people shots are underexposed.

46 Auto Exposure Bracketing (AEB)
AEB enables you to shoot a set of three pictures, all at different exposures. You can then pick the best, or combine the best bits on your PC. As you're shooting RAW, make sure each shot is at least one 'stop' apart.
47 AEB expertise
You can use AEB in tricky lighting conditions in conjunction with Exposure Compensation. With a snowy scene, for example, set Exposure Compensation to +1, then use AEB to take a trio of shots with +2, +1 and 0 stops of compensation.
48 Highlight Tone Priority
Another Custom Function found on newer models, this lets you get more tonal range from the brightest areas of your pictures. It gives a small but significant advantage when shooting landscapes with lots of white clouds - or mostly white subjects (click here for more quick, but great, landscape photography tips).
49 Lock down your shots
To safeguard your shots, find the Protect Images option, then scroll through your images and click Set on each shot you want to Lock. This stops them being erased with a Delete All command (but not a Format command, so be careful).
