I’ve been using Image Composite Editor (ICE) for a while now to stick together the farmhouse project pictures. Until just recently I did not notice I could export the results as a multi-layer Photoshop file. I don’t use Photoshop but GIMP, my graphics editor of choice, can import Photoshop files. Here is the utility room image and I’ve slid the layers apart so you can se exactly where ICE did the stitching. Unlike some old tools, ICE does not use straight lines at the stitch boundaries.
