I have a Canon Rebel XS. Recently I purchased a Tamron 70x200 f2.8 lens. One of the things I do is take pictures for my local hockey association. This past weekend I took my new Tamron lens to a game and based on the suggestions from members of this forum tried a variety of settings. The coach allowed me to sit in the penalty box to take pictures. The lighting in this particular rink is flourescent and pretty poor in some areas. Despite my best experimentation, most of my photos came out underexposed like the sample below. Many of the pictures came out with good focus and I was able to repair the exposure problem in Pshop but I was wondering if I can do better with my settings. The picture I took below had the following settings: Manual Mode -- f2.8 -- 1/400sec. -- ISO 400 -- Exposure bias 0 step -- Focal length 123mm -- metering mode-pattern. I'm pretty much a rookie with this level of equipment. I also tried some shots on Tv mode with f2.8 and 1/500sec and came up with similarly underexposed images. The image below was only resized. There was no other processing done to the image. Any suggestions for getting the exposure better?
