Originally posted by dlh Interesting observation. Why is that, you s'pose?
I find it tricky to get the illumination level right for white. It's so reflective that you must cut the exposure to get any surface texture, but that causes all the other colors in the image go too dark and flat. If you brighten the other colors, the white areas tend to wash out. I you look at Nolecmn's second image above, the white petals and dew drops look lovely, but the center of the flower and the insect there are a bit too dark to be appreciated fully. I had the same problem with the assassin bug on a Queen Ann's lace posted below. I went for best exposure on the insect, as that is the main interest, but the white blossoms are somewhat blown out.
