I have been using Photoshop CC15 to do the stitching and it worked pretty well on using 4 or 5 images taken on the 8 shot pano, but it 'threw a wobbly' when I tried to stitch images from the 16 image pano. But then yesterday I got the CC17 update and I haven't tried it since. There is pro software that does the stitching really well (
Photo stitching software 360 degree Panorama image software - PTGui Stitching Software) but what is putting me off is that you buy software and then have to keep updating it - at a price. One good thing about Ptgui is that there is a trial version available, but when you finalise the pano, it leaves 'watermarking' all over the image.
I would think that since the latest updates - the demand for pano stitching software will increase dramatically. I have also just had a check on Yuneec's Facebook to see if there are any comments or suggestions with regards to 'stitching software'. None! I will have a look at ICE though!
