Night vision type edit with photoshop

Step 1

Open a photo you would like to edit. We recommend using a high resolution image of at least 1000x1000 pixels. It is also fine to upscale a low resolution image before using this effect.
This photo will be used to create the Circuit Board Photoshop effect.

Step 16

Add a new Hue/Saturation adjustment layer (Layer> New Adjustment Layer> Hue/Saturation) as the top layer. Checkmark Colorize and apply your desired color settings. Here are the settings I've used for this step:
