I am making a photo sheet to include in a Christmas letter and want them to be elliptical rather than rectangular. I have made the elliptical selection and have the dancing ants around the selection, but have not figured out how to crop to get just the elliptical part. The crop tool works for the rectangular marquee tool, but not the elliptical.
Guidance would be greatly appreciated
At the point where your marching ants are where you want them, open Select menu and click Inverse. Press backspace on your keyboard once and voila. Now go to Select>Inverse again and Copy/Paste the image into your project, or paste into a New File (with transparent background selected) and save to wherever you'd like to keep it.
What is even easier... after making the elliptical selection, simply copy it to the clipboard (Edit > Copy, or Ctrl-C). Then paste the selection into your project (Edit > Paste, or Ctrl-V). The selection will be placed on a new layer with transparent background.
You might consider feathering the selection a few pixels before doing the copy/paste.
This will give the selection a soft edge which might look better in your Christmas letter.
