Does anyone happen to know that maximum Keystone angle that the DL3 will compensate for? Thanks.
This is actually undocumented given the uniqueness of the fixture. The digital keystone correction on the server is very powerful, but it's difficult to know the maximum angle of keystone correction can accommodate for. There are additional factors, such as the vertical lens shift.
If you the angle it too extreme, you also have to take into account edge to edge focus. So i don't know that I would recommend too extreme of angles.
