I was just doing a bit of screening, and had to reject a whole bunch of shots which were clearly digital camera shots, but were pretty poor quality (not only one photographer). I feel rather bad about that.
I just wanted to remind you guys to make sure you set the camera for maximum resolution/file size and minimal compression (or no compression, better yet). I know that limits the number of shots you can take, but believe me, it is pretty painfully obvious who's been trying to save memory space. You can do a better job downsizing (without introducing jaggies, etc) at home.
Also, take some time to play with the custom settings, in particular the white balance and color settings. Standard settings on most cameras seem to have very obvious results in this areas. Getting good custom settings (where blue sky = blue, not puke, for example) may be a pain in the a**, but it's worth it.
I think you'll be more pleased with your work if you do this, and of course A-net will have better pictures.
