Hey all, I have done a lot of landscapey type work recently and even done some neat shots of cars or people outside, but I always seem to have the problem of exposing the sky and for the subject in the foreground. Anyone have any tips or tricks on getting the sky to come out nice and blue with all the clouds and whatnot and not underexposing the subject? I usually shoot my outdoor shots in the morning before noon and use around f18-f20 on a 17-40 f4L (canon 300d) I have a 550ex flash and have been really thinking about using a fill flash to get the right effect. Anyone have tips or links on mastering how to use a flash? I haven't gotten the hang of using it yet.
