Ok. Camera settings and nitty gritty on flare... so I'm shooting straight into the sun, which I'm trying to "place" either partially behind a tree trunk, or between tree branches, or slightly below a mountain. I'm intentionally manually "over" exposing (which really means I'm NOT exposing for the sun, which is the dominant light source). My aperture is stopped down all the way to f/16 (really small - I want those sun flare & rays defined and focused). Because my aperture is so small (letting in less light), I bumped my iso to 320 (probably should have bumped to 400 or 500 to get a slightly higher shutter speed). I usually only bump my iso as high as I have to in order to keep my shutter speed above 1/100 (the speed I need to compensate for my less-than-steady hands, aka camera shake). And I used my high-tech hand trick to force the camera to autofocus.
