Really gorgeous pics!!! I noticed on these pictures, a kind of darkening of the edges of the picture. It draws you to the middle of the frame and seems to high lite the birds. Do you do this with some type of filter? Roc

Roc- Very good eye!!! That darkening of the edges is called vignetting. It can be achieved several different ways- 1. a filter 2. a lens hood of the wrong dimensions 3. digital photo editing programs
I use an editing program to achieve the look. It doesn't work for all images but for some it just makes them a bit more interesting.
