my main issue with using reference photos for portraits is matching the measurements between photos.
one of the problems i have is finding the head length when the model has hair, this throws me off because i have to guess where the head stops.
also a lot of studio photos the front and side view don't seem to match, it feels like the camera is higher in the side view or it has something to do with the focal length.
i tried to match the photos by tilt them and resizing them but it still don't match.
my question is how do i get a better estimate of the measurements? am i using the reference incorrectly?
