Update: I was looking at some old digital art contest winners and noticed something about the file sizes
I was browsing through the archives of the old CGSociety 'Challenge' winners from 2008. I downloaded one of the winning pieces, a sci-fi cityscape, and the PSD file was only 85 MB. My current WIP, a simple character portrait, is already over 2 GB. I found the stat on their old forum archive page. It just shows how much our tools and expectations for detail have blown up. Does anyone else have old project files that seem tiny by today's standards?
