To celebrate its 75th anniversary, the BFI is going to screen here in London through July and August some of their nitrate prints. For those who don't know, nitrate prints are dangerous, are rarely projected these days but look differently to what we are used to see thanks to their silver content. This is probably the reason why the "silver screen" was named as such. I am not aware of ever seen a projection of a nitrated print for a full lenght feature, but from the combustion of a cartoon in Lisbon a few years ago (mentioned as #1 here) I assume I have seen at least a short.
My only (very minor issue) is with the selection of films - I would love to get a chance to see some of the B&W work of people like Ernest Haller, Gregg Toland or Joseph LaShelle in nitrate, but the emphasis is on British films. Makes sense, I know...
The selection of films for July can be found here, and you'll be able to see the August selection whenever they announce it.
