If needed, one can also align a part of a photo, even with a greater difference in POV. An example from two photos of a wind mill with blocked vanes, corrected on the vanes only. The corrected layer is made transparent on the other layer to see how the rest of the photos have another perspective. The vanes are corrected and cover nicely on both layers. The blue path is from the photo that is transformed (original photo not visible here)
I made some photos from art on beach cabines. Because I set a wrong big resolution on my smartphone and I want the cabines straight on the photos I used the 4 tot 4 points plugin from Ottia Tuota to correct them. I want that the cabines on the different photos have the same size. So I've made one path with this right size and used this to correct the different photos using there own path around the cabin. I used the crop tool to made the dimensions of the photos equal. Example, red lines
