Now, go grab 3 photos that are filled with vibrant colors. The actual contents in the picture do not matter, we’re just interested in the color!
Using a large (500px), soft (0%), black brush with the Brush Tool, create a large black circle towards the center of your canvas. This will be used to help add depth to our design later on.
We need to copy a single row of pixels from one of our images. To do this, we’ll use the Single Row Marquee Tool (located underneath the Rectangular Marquee Tool).
In one of your photos, use this tool to select a row of pixels, and then copy (Edit > Copy or Ctrl + C) that row. Paste the copied row into your design in a new layer.
