Bought this cheap at my camera store. All he knew about it is that it's a 400 asa b&w film & it was cheap. I bought 3 rolls to try. Just says on the canister Premium b&w 400. Ultrafine.com has a film with a similar canister. The emulsion side is a grayish (maybe) green tint (according to my eyes). If anyone has shot this film then tips on development & experience would be cool.

The grey coloring looks just like Tri-X...

Interesting. I don't have any TriX but I do have some Arista Premium 400 that is supposed to be triX. The film on the Arista is darker in color but the underside (emulsion) side is exactly the same. I may shoot a roll & use the times for TriX & see what I get.
 
Stand may work indeed, but what about all the people not having a bottle of Rodinal standing around? :)
- Or if you were to send it of to a lab for development.

Yeah, maybe there are some dev-data inside the packaging (should be, or else this would be in the category "surprise film" ^^ )
 
Am I missing something here? Couldn't this be C41? If you use it and get the shot you have always dreamt of taking, why risk dodgy film/development for that moment?

Stand dev' on C41 - ummmm.

Recommendation - go back and ask what it is.
 
Though the original poster has said that the seller knew nothing, I would get them to check with the person(s) who supplied it.

If you just want to take snaps and say 'it's a lottery' -that's up to you...

Uh, why would you take once in a lifetime photos with an unknown entity? Even with film that has full data sheet I do testing.
 
Looks like the packaging Ultrafine uses. They sell their house brand B&W film online cheap. Don't know who makes it. The cartridge has the same color scheme and type of printing.
 
My guess is it's a C41 film too. Which would explain why there's no other info on the canister.
Ultrafine does not have at the moment any ISO 400 C-41 film.
As Earl is saying; tests are a must, every b&w shooter should develop own film. Sending it to the lab is pointless.
 
If it's monochrome b&w, processing in a C-41 line will ruin the chemistry. So it's best to process in a conventional b&w developer and find out. A snip test is a good option, though given a cheap price I would just shoot a roll at various EI and develop it in Rodinal, XTol or D-76.
