This is a really easy and fun project to try on your black and white digital images, or in my case digital infrared black and white images. You can make all or part of your black and white image a color, and it looks really neat, like a sepia tone or blue, or anything you like. See the examples above and try your hand at this easy Photoshop trick:
Open one of your b/w images in Photoshop. Then create a Hue/Saturation adjustment layer (round button, half white, half grey, fourth from left at bottom of the layers palette) Layer>New Adjustment Layer>Hue/Saturation. In the new layer dialog, choose Color as the Mode, then in the Hue/Saturation dialog, move the Hue slider completely to the left and click OK. The image should have a nice, ethereal blue tint to it. If you used an infrared image, then the trees or anything green will still look glowing white like in the b/w version. Flatten the image (Layer>Flatten Image).
Now, create a duplicate layer (Layer>Duplicate Layer). You now should have two identical layers, one on top of the other, both with a blue tint. Click on the bottom layer (which probably will be called ‘background’) in the layers palette. Then go to Image>Adjustment>Hue/Saturation, and completely desaturate that layer by dragging the Saturation slider to -100.
Nearly finished now. Click on the top layer and select the Eraser tool from your left Toolbox and erase the area you want to remain black and white. Adjust the Levels or Curves. Flatten the image and Save As and name it what you like. Now you have a really neat b/w and color image mix. Fun!
