That's a good point... if you make the effort to keep things constant height then you can use regular (moving side-to-side) curtains for masking instead of moving them up and down to compensate for changing height.

I had been thinking of running a wooden frame around the screen, hinging the top and bottom parts and painting the back and edges black so I could fold them down as masks, but maybe taking another look at constant height is the way to go.

Does anyone know if the anamorphic lenses make the picture wider or just less tall ? I know they can do either depending on how they are designed, just wondering which approach is more common.
