Can Someone Clarify the Scheimpflug Rule for me?

[bobwysiwyg]

I've been working at learning to use my 4x5 (I' fairly new to large format). I thought I understood the gist of this until I came to page 47 of "Using the View Camera."

There are four illustrations. The upper-left and lower-left illustrations are for entirely different movements, yet the text associated with them seems to suggest both movements bring things into focus even if they are along an angular plane.??

I "thought" that generally speaking using front tilt was for one thing and rear tilt for another. I'm not sure now which is associated more with focus vs. perspective correction. Any help would be very much appreciated.

Try reading this for more clarification.

OK, I just looked at page 47. The two diagrams on the left show that you can achieve Scheimpflug using either front tilt or rear tilt (or both as indicated by the top right diagram). This part is about focusing and doesn't consider perspective at all. That's in the next chapter. The common meeting point is what Scheimpflug is all about.

Using rear tilt to focus may result in perspective correction or distortion, as the case may be.

Does that help?

Cheers,
Mark

Um, not sure. Maybe I should just get the cam out and try some things with the next nearby.

Any ideas where the movie files are?

Yes!
Just look at the ground glass. If it looks good shoot it. Sometimes I think we make this stuff way harder than it needs to be.

Cheers,
