My sunflowers were shot handheld while sitting in the car looking out the window, I think. I had the tripod out that day but I don't think I used it on the sunflowers now that I think about it.

I think maybe the high f-stop on the sunflowers and the fact that they're backlighted took away some detail. Anybody else have an idea what's going on?
