Re: Probably a really dumb question for the Photoshop gurus

You will obviously use the Elliptical Marquee tool in this case. When
you are dragging around your selection, press Shift. This will create
a perfect cirle.

I prefer to fix up the center of the circle using Guides. (Make your
rules visible from "View -> Show Rulers" if they're not visible and
drag in two to intersect at the center of your soon-to-be-drawn
circle). Then I draw inside-to-outside by clicking on the center and
dragging out while pressing the ALT (pc)/Opt (mac) key. If I press
Shift + Alt/Opt while I'm dragging, I get a perfect circle being drawn
out from the center. (Helps when I want to draw a few spaced out
circles with a common center).


Method #1 : The qwik & dirty way
--------------------------------
 o  Make your 'fill' colour to be your foreground colour.
 o  Make the selection of the size you want.
 o  Edit -> Stroke...
     -  Specify the width
     -  Specify the relative location
     -  Click Ok
 o  Repeat last two steps as many times you want to.
 o  Do the bonga.


Method #2 : The 'other' way
---------------------------
 o  Make your 'fill' colour to be your foreground colour.
 o  Make the outermost circle using the Elliptical Marquee.
 o  Fill it up. Alt+Del (PC) or Opt+Del (Mac)
 o  Select -> Modify -> Contract...
     -  Fill in the width of the circle
     -  Click OK
 o  Del
 o  Select -> Modify -> Contract...
     -  Fill in the "white space" width
     -  Click OK
 o  Repeat Step 3 - 7 till you want or get tired.
 o  Do the Konga.


Method #3 : The 'oh no!' way
----------------------------
 Note: This is best when you need your circles to be wider
       than 16 pixels.
 o  Make your 'fill' colour to be your foreground colour.
 o  Draw the inner circle using the Elliptical Marquee.
 o  Select -> Save Selection...
     -  Destination: Current document, New Channel.
        Also, give it a name. Eg: SC
     -  Operation: New Channel
     -  Click OK
 o  Draw the outer circle using the Elliptical Marquee.
 o  Select -> Load Selection...
     -  Source: Current document, Saved channel (eg: SC)
     -  Operation: Subtract from selection.
     -  Click OK
 o  Fill it up. Alt+Del (PC) or Opt+Del (Mac)
 o  Repeat Step 2-6 for repeat performances
 o  Ride the Tonga.
