I can't say for certain as we have never used curved screens WITHOUT also using anamorphic lenses; I received this message from one of our suppliers recently with an explanation:



"So, there are two types of anamorphic lens – Prismatic and Cylindrical. They both introduce different types of distortion, which is completely normal and expected in this situation:

Cylindrical lenses introduce a ‘pin-cushion’ effect on the image (ie. Corners pinched out) and;
Prismatic lenses introduce a ‘barrelling’ effect on the image (ie. Corners rounded off)

So, when using a cylindrical anamorphic lens, you get a little bit of pin-cushion effect (which is amplified by a shorter throw). The brilliant thing here is that a curved screen will go some way to correct this distortion, in some cases removing it completely.

When you use a prismatic lens, you get the opposite – barrelling of the image. When you use a curved screen in this instance, you actually amplify the distortion, as you are shortening the throw distance on the outside edges you make the sides of the image even smaller.

The bottom line here is that curved screens are great for cylindrical lenses, and really bad for prismatic lenses."
