Same shark, processed twice differently then merged onto one canvas.
The darker on is lower and appears larger and nearer to the viewer, though both are the same size.

starting with workshop #1 image, I used CHANNEL MIXER to blend the green and blue channels into one grey image. Then I selected the shark and sharpened slightly. Next selected the background and applied a Gaussian blur to rid myself of the digital noise.
Result: a clean image with a reasonable amount of detail and without a lot of work on my part.

mostly used Photoshop's CURVES tool to set the tonal range. I tried lightening the colours but that created white spots.

I simply used photoshop's Curves tool to define the lightest and darkest areas of the shark.
Much better now i think.
