Processed with ZS Pmax, I used my 10X OLY, 200mm Pentax tube lens, Pentax K5.

I stacked the body and wing with similar settings (step size and depth) When I processed the body and wing stacks, I kept the same number of images in each stack and used the same stereo settings in Zerene to make sure the "rotation" produced in the stereo images was very similar. Thus there were more slices in the wing portion of the photo than was needed to sweep the focal plane through the wings. I then used Photoshop to create the panoramas and it did a good job. The final stereo combination of the left and right panoramas was done with StereoPhoto Maker.
