How to Hand Paint a Photograph in Photoshop
Hand painting was originally used to colorize images taken with black and white film. If done properly the effect is still quite stunning.
Open an image in Photoshop (File > Open).
To convert the image to black and white, click the Create Adjustment Layer icon on the Layers palette and select Black & White.
Adjust the sliders to enhance the image contrast and detail.
Add a new blank layer above the image and adjustment layers and set the Blending Mode to Color.
Select a new foreground color for your brush. Lower the brush Opacity and paint on the Color layer
Add additional layers for each of the new colors. Make sure to set the Blending Mode for each layer to Color. If one of the colors overlaps another color, use the Eraser, set to Brush, to contain the painted color.
