Just reviving my practice with this great fish-eye. Here's what I shot today placing the camera to the ground to give you an incredible upward perspective just like from a mouse.
The image was taken at f/5.6, 1/60sec, ISO 200, -1EV, post-processed with a little stronger contrast and some cropping.
Btw. did you notice the dreaded curved lines of the typical fish-eye shot? Not much of them to be seen, eh?
