Photoshop can make anyone "bright"

This was an interesting process tonight. I converted this color image to grayscale then duotone, and changed my default monotone to actual duotone where you choose two colors to (tone) with, I have been using black and white as my two choices but tonight I chose black and gray. I like how that worked out.
