That's actually what the critter looked like... I could have toned it down a bit in post, but the little guy was brilliantly (kind of like a chalky white) so I just left it be. You are exactly right, it would make a better picture, but it wouldn't describe the critter accurately.
No, it isn't the Nikon system. I tried one of those (two flashes) and didn't care for it a bit... the dumb flashes keep popping off the ring when you walk around over rough ground, then you have to stop and pick them up and hope they haven't been damaged when bouncing off of lava or something. I am using an el-cheapo third party flash ring. It is i-TTL compatible, and so far I really like it. $130 at B&H, so you can't go too far wrong.
