It is a 16mm Scope reduction print intended for smaller theatrical release, or for large clubs etc.
It is anamorphic scope.
I can control my LEDs to match the correct colour temperature, and will be grading the final result in Shake to get the colour as close as possible to the original print.
The reason for it is that the original 1977 version is not available any more, only the 'Special Editions'. This is a rare print that pre-dates the Episode IV in the title as well.
It will be to back it up so that it isn't lost, but obviously I'd like to view the finished result as well
