I would like to use the Ellipitical tool for selecting a portion of the circle.
If you can imagine drawing 2 circles with the Ellipitical tool so that they overlap each other until there is just a sliver between the two circles. It's that sliver that I would like to select so that I can fill it in with a colour or touch up tool.
Would appreciate it if you could give me some pointers.
Thanks

Make your selection on a new layer... fill it with the color you like. Don't release the selection though, instead with the marquee tool still selected either click and drag or use the arrow keys to move the selection over until the sliver is defined by the "marching ants". Hit cmd+J (ctrl+J) to copy just that section to a new layer. Delete the original layer.

You could do this by making a selection and making a new one and minusing them, but it's much harder to get it right.

Alternately, if you just used the pen tool you could make that same shape pretty quickly and it would be a vector you could scale.

Hopefully that helps. Good luck.

Draw a circle with the elipse tool (keep pressing shift for a circle)
Duplicate it (Path selection tool, Alt drag first circle)
position as you like
select both circles, click "Intersect Shape Areas" top toolbar, third button.
Now change fill, add styles, change size, and so on...
If you want it to became an image (I can't see why but here it goes...) :
New layer, ctrl+click Shape Layer thumbnail, fill with desired color.

Paths (shapes) are a great tool!!!

Good luck

Thanks Mindbender and Uniko for your suggestions. They were both helpful, I tried them both but for my application I found that Uniko's worked for me best.
Thanks again both of you for your help.
