i want to be able to take 2 or 3 photos of my model railway layout and stitch them together to form one photo - similar to a wide angle photo. Is this the right system for me? I have had one attempt, but the join is very noticeable. Any way I can improve this? I also am not sure how to transfer to the photo folder on my computer. I tried to cut and paste, but the resulting image is much smaller than my normal photos. Any suggestions? Thanks.
