I am using either Photoshop CS5, or Autopano Pro. The version of Autopano Pro I have doesn't work as a plugin, one of the reasons I often use Photoshop. Autopano Pro is in my view the better program but in simple cases Photoshop makes an excellent job.
I use stitching more since I started MF, on the Hasselblad I don't have zooms and I often get into a situation where the subject just doesn't fit in the frame. So I shoot 2-3 images with some offset and stitch.
I use LR 5.2 and a plug-in of some sort would be great. I'm pretty good at learning algorithms but don't want to waste time and effort on a dud.
Thanks in advance, as always.
