Re: Full Screen on digital projector??

Thank you Bostjan and Don.
I suspect I should load a few full screen panoramas on a CD-R and go
give it a test with their projector before I commit. Or I might
need to find another presentation method.
This group of 150 to 180 is mostly film photographers with about 20%
digital folks. I need to make this presentation high quality.
