For canon, see thru viewfinder, bottom right, it is Max Burst. What it is? I can't find the manual book.
Hames, the max burst, is how many photos your camera will take on continuos shooting befor it's buffer fills up and can no longer take shots w/o processing what has been shot to the card. If you put the camera in jpeg mode you will notice the number gets higher. It will probably only matter if you are on continuos mode. In one shot you probably can't shoot fast enough for the max to matter. Make happy burst. Good luck
