Experts, I am seeking some advise. equipment used: xti, 580EX, EFS 18-55 and 50mm 1.8. Weather conditions: 1PM, sunny with no clouds, temp 65F, light wind. task: portrait photograpy in a open field (no trees, green grass, open area) positioning: one shoot facing the sun and one shoot at 90 degrees to the sun. so I started with ISO200, Tv mode at 1/80 with my EFS first, no flash, the set I took turned out to be full shadows on half of the face of the subject. with Flash, the pictures turned out to be too "white" not just bright. So is my setting wrong, do I need to bump my shutter speed, do I need to shoot in Av instead. I do not like to use the flash to fill in, I like to get the photo from natural light. Please help, thanks.
