Creating an Infra-Red Night-Vision Effect

The first thing we will do is to create a new pattern to overlay onto the image to get that scanline look. Open a new document of about 10x10px. Zoom in, create a new layer and delete the background layer so we're working on a transparent canvas. Now draw a 2px black horizontal line at the top. You can hold shift whilst using the Pencil tool to draw straight lines.

We will start with the following photo:

Press Ctrl+A to select the entire canvas and then goto Edit > Define Pattern. Give it the name scanlines.



Now go back to our original image, and create a new layer. Fill the new layer with a solid color so that it fills everything. Now look at the top of the Layers window and see the Fill option below the Opacity. Set the Fill to 0%. This will make everything in the layer transparent.



Next, open up the Layer Styles for this new layer and choose color overlay. Set the Blend Mode to Overlay, and choose a Green color. You may also want to reduce the opacity, depending upon your image and the look you want.
