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.
Step 3: Changing the background colorsIn this tutorial we're going to add all the adjustment layers non-destructively by clicking in the "Create new fill or adjustment layer" like shown in the image below: Using this technique, add a Curves Adjustment Layer going to 'Create new fill or adjustment layer' > Curves and change the RGB line based on the image below. We don't want the sky to be brighter, only the ocean, so we're going to change the layer mask of the adjustment layer. Click on the layer mask of the Curves adjustment layer, select a soft brush and paint the sky with black to hide the adjustment layer in that area. Some quick tips:
- Press D on your keyboard to return the colors of your palette back to Black and White
- When painting a layer mask, black will hide the layer, and white will reveal it again
- If you make a mistake while painting a layer mask, you just have to paint the area where you made the mistake with white again
- You can quickly change between your background and foreground color by pressing X
- To hide a layer mask, hold the Shift key and click on the mask. Do the same thing if you want to reveal it again
