Need help making concentric arcs in Photoshop

[candlefish]

I'm attempting to make three concentric arcs, each one on top of the other at equal distances from each other. My ultimate goal is to make a logo with the letter j, with the three arcs emanating from the dot of the j (to represent sound waves). I started off making an arc with the pen tool, then scaled it larger and copied it. The problem is that each time I scale and copy the arc, the new, larger arc changes shape slightly (not just size) and doesn't match the smaller arc below it (the curve is a bit different). Any help with this would be really appreciated!

(I tried making the arcs in Illustrator but couldn't figure it out, so I've also posted a thread in the Illustrator forum)

I don't know how you'd do it in Illustrator (probably a lot easier than in Photoshop), but I've written you a quick tutorial on one method: Concentric Arcs Tutorial

There are probably lots of quicker and easier ways, but this one does the job.

Tamlin to the rescue! I appreciate your taking the time to write an arcs tutorial, it worked beautifully. In the final version I wanted the arcs vectored with no background, so I went back into Illustrator and was able to get what I wanted within 10 minutes. I’d been trying to get the arcs around the dot of a “j”, and since the dot wasn’t a perfects circle I couldn’t use the circle method. Finally decided to outline the font, delete the imperfect dot and make a new one with the ellipse tool. From there, using the ideas you provided in your tutorial, I made three new circles, stroked them, and then cut them with the scissors tool to obtain arcs. Fairly simple, but I was stumped until I tried out your Photoshop method. Many thanks.

Unfortunately I don't know anything about Illustrator, but I'm glad I was able to help in a small way.
