Color Managment I've been imaging products for a catolog and web site. The problem I've been having is that when I take two pictures under the same settings and I end up with completely different pictures. I have a Cannon Digital Rebel on jpeg and no matter what Appature or shutter speed I use I never get the consistency I need. Please I'm open to any advise that you could supply.

Hi April. I think we need a little more information here :-) What are your shooting conditions (studio, outdoors etc etc). What lighting are you using (flash, studio 'hot' lights, natural light etc etc.) What are you imaging?? Post a couple of samples so we can see what 'completely different' actually means, a picture is worth 1000+ words. Lots of advice will be forthcoming. Cheers

I'm sorry!!! I have an indoor studio with hot lights, two with 500 watt lights, and I image camping and outdoor sporting goods. The difference in the pictures is one will have my white background perfect the other will be grey or too washed-out. I have switched to a raw setting which has seemed to solve the problem so far. But I'm still not sure how it happened in the first place!! Thank you for any advise!! This is a subject I love to learn more and more about. April

Like all light meters, the meter in your camera is trying to average the scene to an 18% gray. If you have different amounts of white background with different objects and object sizes you will find that the camera will produce a variation on automatic. The best way to solve this is to go to complete manual in the camera, use incident light and do not change these settings. Not only do you have to go to a manual setting for shutter speed and aperature, you also have to go manual on the ISO. You can't let the camera compensate.

I agree with William but, I have one additional sugestion. With the Canon SLR family white ballance is a seperate from the other manual settings try taking the camera off of auto white ballance (AWB) and use one of the other settings. Experiment with them. The right one will depend on the accual color tempature of your lights. I hope this helps
