I've just received an email from the wonderful folks at RetroPhotographic informing me of their plans to market glass plate negative film.
They will be expensive, and they need a "small number of customers who are prepared to place advance orders (don't have to pay in advance) so I don't have the money sitting on the shelf when the product gets here."
The price they're looking at is:
13x18cm 6 per box £55.32
5x4" 25 per box £149.00
9x12cm 6 per box £40.00
Expensive, yes. But might well be worth it for that extra bit of "authenticity"! Besides, all concerns about film flatness will be a thing of the past
They have been very easy to deal with in the past, and their POP paper is wonderful!
