I am going to my daughters' basketball game tonight...haven't been in this gym before (away game). Our gym, however, causes the pics to look yellow and I have a real hard time with the speed. Can anyone help with settings and lens? I have a Digital Rebel XT, a 50 mm, 75-300 mm and a kit lens. Also have a 430ex speedlight. Suggestions as to which and how to use would be greatly appreciated!
