For ages my moderately nice camera has been frustrating me by burning the bottom of some of my pictures. I know it seems odd, but that's the only way I can describe it. It happens when I do a burst of 5 - either to catch something that's scooting past or to get a range of exposures for making one of those ugly HDR images that were all the rage a month or two ago. Anyway - today I worked out what it was.
Looking closely at the images it was clear that the brownish area at the bottom of some of them was actually stripey, as though the last few lines of the image had been corrupted. I'd thought before that perhaps the memory card was somehow too slow and not recording the data fast enough, but it was a very fast one, supposedly so I abandoned that idea. Now it appears it was too fast, and my stately camera was getting confused by the speed with which my shit pictures were disappearing off its shovel (as it were). I just tried taking loads of bursts with a slower card, and they've all come out fine (although a waiter at the restaurant opposite did make as if to come and stop me, so I had to point my pointless bursting elsewhere for a bit).
