Wolfman, that was a good 1 and easy.
Here's my best result:
1) Dup Layer
2) Select Color range (white on brackets)
3) Lasso Tool to deslect everything but the board
4) tried to get as close to fingers as possible
5) Image > Adjust > Exposure
-- Exposure -0.4 -- Offset 0 -- Gamma 0.75
6) Image > Adjust > Levels
-- Black and white to edge of histogram
-- Output Level 50
7) Image > Adjust > Curves
-- Grey Smapler and choose a darkler grey from a background shirt (made it almost white)
Merge Layers and done.
