This is another picture - one of my many "throw aways" from the trip. This
picture is bad for two reasons. It has backscatter and I took it from
too far away, so it looks blue. However, it makes a good image for this
lesson. (this was the biggest puffer I had ever seen, that's why I took
the shot - it was about 3 ft long).
First, I used a levels layer and adjusted the color, adding back in
red (the color you lose quickest underwater) and removing some of the
green and blue. This photo was taken at a depth of around 70 ft. I then
used the scratch and dust filter to take out the backscatter. Click on
