I only really started shooting raw a year ago as disk space and flash memory came down in price.

I now shoot everything in raw, even fun stuff because you never know when that one image might be useful down the road.

Ive got a D700 now which outputs 15mb raw files, my previous cam the Fuji S3 had 25mb files but with 1tb drives available so cheap plus 32gb memory cards theres no reason not to.
