I'll ask the lab about the IR light/night vision, but I don't think they use them-it seems like the entire crew at BFL work in a 20x30 storefront, the place is pretty jam-packed with folks running scanning machines and photo software.
Considering expired is the only IR film with any sensitivity beyond 780nm available, that's the only option. Aviphot 200 isn't likely to be made again, just like 400 and 400S ran out, so Maco swapped IR400 to being Aviphot 200 just like the other Rollei films. When it runs out, I guess they'll just change the film and keep the name again. I like the look of Konica 750 but it's all expired, Efke 820 was the last batch of IR film made that I can find any mention of, and it's all from 2012. (And 400+$ per 10 rolls, the few places I've seen it for sale.) I got lucky with the Macophot, I mentioned Saturday that I was trying some IR photography and one of the other photographers in the park offered it to me as they now do their IR with a digital camera.
I still haven't decided if I want to dive into developing film myself-I have all the tools, as my grandfather had a darkroom before he moved down to where we all live at now, but I don't have a good storage area for chemicals that are temperature or moisture sensitive. The photographer that gave it to me didn't mention anything about it being hard to develop, I just read some tales on the internet about it.
