The process was to convert the image to B&W as a new layer via Photoshop using a custom setting. The next step was to use the Select Color Range Shadows and then darken the shadows via levels, for the shadow range moved the midpoint (gray) to about .5-.6. Then used the Select Color Range Highlights then brighten again via levels but this time moved the shadow marker to the edge of the information and then moved the midpoint (gray) to about 1.75
