"I shoot a lot of outdoor sports in the bright Colorado sunshine. The center focus would sometime include their shirts, which can be black, white or any other color in between which would really throw things off."
I would like someone to post regarding this remark..My understanding is that when shooting moving objects ( such as sports here, or in my case running horses) matrix is the best choice since if using any type of spot metering ( center or regular) you do have a higher chance of this happening.Unless you are really good at moving that focus/metering point, or can meter off something on the field or a gray card) and lock in that value. ( using Peterson's Understanding Exposure tips of "brothers" for example. When I am shooting pastured horses I will sometimes get a reading using the sky or grass and take a few shots until I get what looks good.Then leave it there.Unless I am shooting bright white horses in bright sun.Then I spot the horse)
