Having an unusual 2.00:1 ratio screen, I need 4-way masking. Well, 3-way masking - films which are 'too narrow' for the screen need a mask at each side, but films which are not tall enough ('scope) only really need masking at the bottom, with the image racked up to the top, rather than keeping the image in the middle and masking both top and bottom.
If that's not clear now, hopefully it will be once I've posted pics.
I've decided to make the masks from polystyrene sheets covered with self-adhesive velvet.
Okay, the new masking is very much in 'testing' mode at the moment.
I made the 'masks' with a lot of help from a mate (for clarity, he did all the work) on Friday.
I only bought a 1m x 45cm roll of the self adhesive velvet yesterday, and I have four pieces of masking. Clearly that's not enough, but I wanted to experiment.
My screen is 2.00:1 ratio at 280cm x 140cm. So 1.85:1 is 259 x 140, whilst 2.40:1 is 280 x 117. That means I need two masks for each side, each 10.5 x 140, and a big mask for the bottom of 280 x 23.
As the polystyrene can't be bought in sheets 280cm long I've had to make two pieces of 140 x 23 each.
Yesterday I covered one of the side masks completely and half of the other with the 1m x 45cm roll I'd bought. This velvet will be coming off, and replaced. I just wanted to try several techniques.
Pics and links later.
But the one thing clear from watching a 1.85:1 film last night is that the masks 'work', in that in use they created a solid black border for the film, and were indistinguishable from my fixed frame screen's black velvet borders.
They also stay in place.
