Of course, cams are becoming 15mp these days, just like the 50D, averaging 18mb a raw! haha I know because I'm using it. I've just have to get more terabyte ext HDDs. Luckily its cheap nowadays
I always shoot in RAW and the sizes do build up quickly.
That's why once I transfer them from CF to comp, I will need to work on them asap.
Well, in a way I'm also eager to see how they look on the screen as the cam LCD can be inaccurate.
I feel the main factor will be to take a step to start on them. Be it for anything, if they start to snowball, anyone will be put off with that amount of work needed to catch up.
