I am planning to go back out for my grandmother's 70th bday party, back to the park/beach. It has many many trees that cast alot of shadows on people's face, and then of course there is the sun, where there is no tree's w/ the water behind it... so here is my question.. what is the best thing for me to do? I have been taking most of my pictures in AV mode. My aunt is up from SC and has an Nikon and she told me she shoots only in the portrait mode. I tried that last night... it used the flash and looks like the pictures came out good (at least in my house).. Soo.. what do I do? I am not good enough to use manual yet.
