I was out shooting some early morning dew covered cobwebs with my D5300 + 105VR + SB-800 and got the following image. Shot in M 1/200 @ ISO 100 @ f4.5 and Manual Flash at maybe 1/16 power. I've over JPEGed it to make it fit here, but the 2 big angled magenta and green bands are equally visible on the RAW. Is this normal CA behavior with a high contrast subject like this or is there something wacky going on because it's flash and spherical water drops (I don't think so!) or what?
