Matching a Vertical Nikon D200 to a Maya Lens

When you shoot using your camera in a vertical aspect ratio, you don't do anything special but turn your camera. To match Maya to your DSLR you need to make an extra little adjustment. When you swap the resolution x and y, you have to swap the horizontal and vertical film aperture values as well...

Here is a rectangular polygon mesh just the right size and shape to fit into a Maya camera resolution gate after it has been set to mimic a Nikon D200. (as described here)

A horizontal Nikon D200 full resolution frame is 3872 x 2592.

. . . if you simply change the resolution . . .

. . . and if you simply rotate your plane 90 degrees you'll see it still no longer fits . . .

You need to swap the values in the 'Horizontal and Vertical Film Aperture' fields as well. It may seem obvious, but it's easy to forget.

Another solution is to leave the 'Film Aperture' values as if for a horizontal camera match, and change the lens from a 50 mm (in this case) to (it turns out to be) a 33.5 mm lens. But who wants to do the necessary work to figure that out?

So to match a horizontal D200 to a Maya camera, don't forget to set the

Horizontal Film Aperture = 0.622047244, which is 15.8 mm in inches

Vertical Film Aperture = 0.929133858, which is 23.6 mm in inches

Then your Nikon D200 lens should match your Maya lens.

A 'full frame' Nikon D700 has a chip size of 36 mm x 23.9 mm.

At 1.417" x 0.945" Maya's default camera back equates to 36 mm x 24 mm. So Maya default cameras equate directly to Nikon D700 lenses.

Don't forget to swap places with the 1.417 and the 0.945 values when you go vertical with the resolution.
