Why Does My Camera Write Slow? I love my Canon Digital Rebel XTi ... however, when shooting fireworks, it writes extremely slow, causing me to lose some good shots. I have turned off the viewing, tried different file types (Raw vs. JPEG, smaller or larger) but nothing helps. Any suggestions?

Hi Karen, The modern digital camera features chip logic - i.e., the camera’s main chip or CPU has all manor of built-in computer enhancing programming. These are computer routines that improve the images we take. Especially rigorous are the routines for situations that present a photographic challenge. You would be unhappy if you turned off these enhancements. We pay the price which is a longer processing time. We gain by better images.

if you are shooting at slow shutter speeds (1 sec or slower), it does take longer for the information to be processed & written to the card. Long exposures on Canon dSLRs with noise reduction use a dark frame to reduce noise. The shot still consists of one single exposure but then there is delay while the dark frame is taken and then the results are combined and the result written to the card. For fireworks, you should be shooting 1/15 thru 1/40 of a second range, and it should be a faster write time. I just shot a fireworks show, and at f/8 thru f/11 and ISO 400, I was shooting between 1/20 and 1/30 speed, and they were writing fast enough to keep up with the show.
