I have to do some frontal images of a row of buildings, and am struggling with getting the camera parallel to the facade. It seems the slightest degree off leads to a perspective slope away to one side or another. Is there some simple trick to getting a camera in parallel alignment with a flat fronted architectural subject you face?
I'm stitching 3 vertical images together, and one side or another often reveals I didn't get it quite right! I know I can do horizontal keystone in C1 if needed, but I'd like to get it right in the camera before I resort to that (plus it makes stitching alignment difficult when you keystone 3 images by differing amounts)
Thanks in advance
