Sorry if this is a repeat for some of you. I am copying a post from elsewhere, so skip it if it sounds familiar already.
"Ok, I am setting up for some still images. One piece will be for a convention panel (30 X 40 inches). Then the client want's a triptych, where the image is the same as before except extended to 3 times the width.
The problem is that we are trying first to recreate the vertical layout to match the client's specs. So I need to set up that first. THEN, I need to get the horizontal layout to match even though it's 3 times wider (It would be nice if I could set up the wider piece and just crop, but I don't think I can get away with that).
I figured I could simply copy my first camera, then triple the aperture width. But when I do so, naturally the FOV angle shifts. Doh! So the angle, compared to the first camera setup, is slightly off.
Anybody know a mathematical way to approach this? I could play with the FOV angle but it is guessing right now, and I'd like to have more certainty."
