This procedure is called 'rectifying' and is used in making maps or mosaics from large quantities of aerial photos from planes that are not always flying straight or level.

Since it was in widespread use at one time, they made both an enlarger and an easel with this tilt capability built in. Could be that some of them are still available on the 2nd hand market. They were called "rectifying printers" or "rectifying easels".

If you used the corresponding rectifying camera, built in data was printed on the border of each exposure that gave a printout of the gyroscopic information (deviation) of the plane from its planned course and this could be dialed into the equipment in the lab to auto correct each frame. Without the special camera, you had to guess, and most often it would correct the print but overall the entire map would be pretty useless as scale would not be exact. I have seen a road vanish from one photo pair to another pair through manual correction which distorted the edge at a junction between all 4 frames.

Of course, this is all now done by sattelite mapping.

Sorry, but I have nothing more to add other than the name and use.
