I didn't start shooting raw until 2008, and only with the Sigma DP1 because it was necessary to get a decent image from it. Hardly any of my Canon G series or DSLR images were in raw until 2009 or later, so there's years of images that didn't get the benefit of raw. 30D and 5D Mark II jpegs were pretty malleable, although the real benefits came from raw. My photography mentor told me as early as 2004 that I should be shooting raw, but I didn't take her advice for ages. Back then, CF cards (remember those?) were expensive and limited in storage - a 1GB card was like a square of gold - and I liked to shoot a LOT. So rather than limit my ability to shoot, I used jpeg for years.Yes, I cringe when I look at some of my earlier efforts.
