Mirror bounce is caused by the mirror flipping up and unsettling the camera just as the shot is about to be taken. Any movement on the part of the camera will cause blurred results in macro shooting, especially when you’re not using the short pulse of light from a flash to freeze motion.
You’ll find that even if you use a remote controller to operate the camera, so that you’re not actually touching it, mirror-bounce will still degrade the sharpness of the results. Most DSLRs feature a Mirror Lock-up facility or an Exposure Delay mode to fix the problem. Here’s how they work on many current Canon and Nikon DSLRs…
Avoid mirror bounce on Canon DSLRs
01 Mirror Lock Up
Current Canon DSLRs, apart from the Canon 1100D, have Mirror Lock-up in the Custom Functions menu. Set this to Enable, then do the following…
Select Self-timer with a two-sec delay. This gives the camera a chance to settle. You could also use Mirror Lock-up with a remote control.
Avoid mirror bounce on Nikon DSLRs
01 Exposure Delay mode
Most Nikon DSLRs have an Exposure Delay mode in Custom Settings. This delays shooting for about a second after the mirror flips up.
02 Mirror Up
This can be found in Nikon’s Drive modes. For remote shooting, set Remote Mirror-up in the Remote Control part of the Shooting menu.
