I took this picture today – through my kitchen window, from about 30 yards out.  If you look closely, you can see a cardinal in one of the trees.

I uploaded it to some photo editing software that I downloaded from the net (Faststone Image Viewer), and zoomed in on the bird.  The first attempt came in like this:

Thinking I could maybe get even closer, I zoomed in again.  The final picture looks like this:

If I make it any larger, I loose a lot  of clarity.  Even so, for a shot taken through a window, I think it came out pretty good.
