I have a Canon Rebel t2i with the EFS 18-55 mm lens and the EF 70-300 mm f 4-5.6 IS USM Telephoto Zoom Lens. I have been taking pictures all over. I would like to ask my first question of this forum, and please tell me if I should post this somewhere else. I was at work photographing a sunset. I was really trying to get the highlights around the edge of the clods to stand out. I was originally in Av mode @ about f30. I bracketed my exposure. Unfortunately, the photographs that really showed the details in the clouds were the ones that were slightly underexposed. I tried in Tv move and used longer exposures with the same result. Any hints on how to get a properly exposed cloud with highlights with the proper exposure.
