I have a Canon 20d and for my advanced Digital Photography class i have to shoot in RAW format. The instruction booklet is short and not helpful. How do I shoot this format? I'm going out to get a picture downtown tonight and I'm taking pictures inside right now and their black. I've got it on manual mode (another I have to do) and I chose just RAW without +JPEG. The top LCD is flashing under -2 on the exposure level indicator. I've been shooting JPEG's and with the K color temperature. I'm trying to google how to shoot RAW with my camera but I thought I'd post here as well. I don't know anything about RAW and any advice and info. anyone can give me would be extremely appreciated.
