Perspective! You can’t live without it, but it hates your guts! Well, you can use Photoshop to tame the perspective shrew. Let’s take one example, the dreaded problem of circles in perspective, and see what Photoshop can do for us.
Here’s a piece of art in progress, taken to a rough sketch stage. After you have laid in your perspective grid, and scanned it in to Photoshop, make a constrained circle of roughly the right size.
Here are the steps:
1 – Create a new layer
2 – Use the ELLIPTICAL marquee tool to create a round selection. Constrain to an exact circle by holding down the SHIFT key.
3 – Edit > Stroke to stroke the circle with a line (I used 2 px in this example).
4 – Deselect.
It should look something like this:
Use the Transform tool. Hold the command (or “apple”) button on Mac, or Alt on PC, to move ONLY the corner anchor points. By moving the anchor points individually, line up the corners of the transform box with your grid lines like this:
Be sure to move the whole box back into place as you go, with the center point of the transform box always remaining in the center of your perspective circle, as I’ve done here.
