with two "before" "after" photos, find the points of concordance and modify one or both photos so that the transition from one to the other is as finely carried out as possible
hi, no , it's not the same work, what I think is being able to obtain two images whose characteristic points are very close, in order to make the closest "before" "after" to put them on a site. ex: old postcard and recent shot, whose focal length is not identical, and the framing is not quite identical either
