How To Color In A Black and White Photograph With Photoshop

Here's a simple way to make a colored area in a Black and White photo using Photoshop.

1. Open a color photo in photoshop.
2. Press command a, command j to create a new layer.
3. Go to image->adjustment->desaturate to make the new layer a black and white image.
4. Use the eraser tool to erase the area you want to be in color. The eraser tool is sized by adjusting the brush size. The larger the number, the larger the area that will be removed. I start small along the edges and then use a larger brush to fill in the rest quickly. Make sure the brush hardness is set to 100 so that you have a crisp edge.
