I'm just starting to develop this issue, because I only owned an SLR camera before my DSLR. After only a month, I used up 2gb (could have been more, but don't have that much time for photos
).
Also, I was just wondering, what's the differance between a RAW picture format, and the "normal" format that is automaticaly saved as a .jpg? I can see a huge file size differance, but I don't see one when I make the transfer onto my pc.
