Labs to develop E6 and C41 colour ULF films

[Mark A.]

What labs might you use to develop your your ULF colour films (E6 and C41 processes)?

[Drew Wiley]

Does ANY lab develop ULF color film? What do you mean by that? 11X14?

[Mark A.]

That is what I am trying to find out since Canham Cameras sells boxes of 20x24 film (C41). He also sells some E6 film in ULF size.As an experiment I taped two 8x10 E6 slide films together in an 8x20 film holder with a very pleasing result.
Could I then just purchase 8x20 film or 12x20?

Why not ask Keith Canham if he knows of any?

Edgar Praus (https://www.4photolab.com/) lists E-6 up to 11x14 and C-41 up to 8x10 on his website - might be worth a query.

Keith does not know where his clients develop their film but I will check this potential source. Thanks for the information.

Northeast Photographic https://www.northeastphotographic.com/ does large format C41 and E-6. I don't know how large they go, but it's worth an inquiry.

My guess is that they are using a Jobo or alternative dip/dunk methods. I've seen videos of commercial dip/dunk systems put in place in China, likely for rich connoisseurs who don't live in a country with much care about water pollution or chemical runoff

If you can afford to buy whole runs of ULF film, I'm sure that spending a couple thousand dollars to have some custom tanks made, or buy a Jobo ATL machine and some large print drums, isn't too hard.
Canham has posted pictures of entire runs of film that was ordered by a single customer "overseas".

Praus Productions develops 11 x 14 E-6 film, apparently with dip-and-dunk.
