Hi, I am at work taking pictures of some consumer products in a light tent with a Canon Digital Rebel 350D SLR. I've been taking them manually, at about f/4.5 and an exposure time of 1/40 sec, with an ISO of 200. I've been bracketing that exposure time with a slower and faster one just in case. Here is the problem: some of the products have dark areas and light areas. If I want to expose the dark areas correctly, it seems the lighter areas always come out too dark. I'm an amateur photographer, so I'm not sure what to do to fix this problem. Does it have anything to do with metering? Is there a setting on the camera somewhere that helps with contrast? My boss doesn't want to use any software to edit the pictures... Any suggestions? Thanks!
