Turn any photo into a dot grid artwork with these Photoshop actions. You'll get great results with dots that change size. They get larger in brighter areas and smaller in darker areas. Free download available.
- Create a new layer and position it above all the other layers.
- Load the selection of the characters then use the Gradient tool to create a orange to blue gradient. Because the light source of the drawing used for this tutorial is from the left side, I will draw a gradient from the left to right. This will make the left side warmer and the right side cooler.
- Change the blending mode of the current layer to Color.
- Lower the opacity to about 10-20%.
