quick question

[Photophreak]

Hey I'm new here and got a quick question from my photography class. Hopefully this is the right sub forum. What in large format photography refers to the theory used to find the focal plane before exposing an image? Thanks for your help!

Google Scheimpflug.

Hyperfocal Distance might be more appropriate
