I need to know the very most BASIC user's instructions for my 420EX flash. I have never used any shoe-mounted flash before...at all. So I'm looking for some basic settings to at least get me started for indoor shooting, but even more importantly, for outdoor fill flash usage. I shoot with a T2i camera and plan to use both a 50 1.8, and 70-200 f4 IS lens. I will use a flash bracket as well. I understand that you will not be able to give me detailed instructions(and I really don't have time to learn those)because the ambient light (especially for the outdoor shots....which are the more important ones for me)differs by the locales. So just a couple general settings that might get me OK shots is all I'm asking for right now. I've got myself in a bit of a bind, and only have VERY little time to experiment before I must take the pictures. Not the ideal situation, but one that I'm stuck with. Thank you sooooo very much for helping me out.
