This photograph was taken near Bill Schwab's place up in northern Michigan. The vignetting was due to stacked filters (polarizer + light green) I was using to cut down reflections and bring up the submerged grasses. I was planning on cropping out the vignetted corners, but they seemed to work OK with the impression I got when composing the picture- a microcosm in this little stream.
This is exceptional! A cliche subject done with originality and style. Good for you! I wish it were mine (and I'm scouting the 'pads for the decisive moment )
Once again you've outdone yourself. Fantastic image. The vignetting really works- it gives it this sort-of fisheye feel, without the fisheye distortion.
