The whole purpose of using a 4x5?
Numerous: The film area is 4x5 inches in area, which will scan at around 100mp.
The front of the camera (where the lens is, which is called a "standard") can be tilted left, right, sideways diagonal (swivel) and moved up and down. The benefit of this is to correct verticle and horizontal lines, very useful for architecture and interior photography. The back also has a bit of movement, similar to the front.
The downside is the film and Polaroid cost.
Roughly $150 for a pack of 20 Polaroids and 80-90 bucks for a 10 pack of transparency sheet film.
Disregard the cost, write it off as a hobby and the results you can achieve from a camera like this is mind blowingly beautiful

Just thought I'd share some awesome stuff from the past
