av8er23:I am totally convinced those pics are of the same sponge. I was experimenting with my camera on this trip and taking about half of the pics with the UW mode and half with manual white balance. The one I took that shows the brilliant orange color was taken with the manual white balance set at that depth. It does do a great job allowing the bright colors to come out but I would like the photo to have that natural blue color of the water.
Any tips?
btw. natural color of water is not blue
manual white balance gives you exactly what you want: natural colors...
