Nichole Young demonstrates how to hand color using layer masks in Photoshop CS4, which also works in Photoshop CS3. The procedure can be summarized in two stages: turning the picture you would like to edit black and white and then bringing color back into it to give it a hand-colored look. The black-and-white effect is achieved by creating a new layer over the background layer. The next step is to give the picture a warm look by adjusting the layer's respective color balance. Then bring the colors back into the picture by using the brush tool and zooming in and out as finer details need to be painted. Use the density panel to even out the colors and make them look either more bleached or saturated.
