How can I create concentric circles in Photoshop CC?
I'm sure there must be an easy way but I cannot work it out :-(
Create a circular Path (or Shape Layer) duplicate it and transform it while keeping alt- and shift-key pressed.
Each Circle may be made by using the Elliptical Marquee tool and setting the same H & W numbers in the Options bar
Edit > Stroke
Place each anywhere in the image area but each on a separate layer
Choose all those layers in the Layers panel
Use the Move tool, and in the Options bar click the vertical and then the horizontal alignment symbols.
Flatten the layers if desired.
Thanks for the help folks, much appreciated.
