What irritates me with this explanation is that the SO-number is so low.

But actually there is no publication that states how those numbers were chosen...
From the existing listing one cannot deduce on not-listed numbers.

Edited: I confused the SO number. Sorry for the noise.

My friend loaded up his camera and made a few exposures. I took it home and developed in Blazinol 1+49. Probably not the ideal developer.



Other than it being quite grainy, it's got nice tones.

Well, Andrew, It looks that somebody throw a few bulk rolls of this strange film in Vancouver film supply? Just found another 100' or so roll of it. Shot test from 400 to 0ei, processed in C41. Looks like now is around 50-25ei and grainy. Colors are correct. There are no frame # and only marking K'ODAK SO147 and emulsion #.Will try it again in E6, since orange mask is not there or I can not see it? Can color negative lose orange mask like here? First negative is scanned on proper film scanner. Second rabate shot is DSLR fir and last, negative page is Iphone on light table.

I most definitely can see the orange mask.

Yes, I can see it on the negatives alone but I'm surprised by lack of it around rebate and perforations. I'm used to much more pronounced mask on fresh "normal" color negative films. Do not have much experience with expired or very expired color negative films. Can high base fog obscure mask?

I don’t know... IIRC, @Photo Engineer has said before that the mask is a positive “image”, so I guess it’s light sensitive and is developed like a color “layer” in the film.

But I agree that most films have a more dense mask on the rebate.

Kodak TC400 Film, code SO-147, was an aerial & industrial film. The film was designed for use in traffic surveillance and other specialized industrial applications (security cameras, for example). The film was discontinued in early 1999. The film is now 20 years old, so colors may not be accurate anymore.

Fog will obscure the mask.

Andrew O'Neill's attempt to develop it in a B&W developer, given the film has to be old and C41, has turned out quite well, I thought

Just a tad on the grainy side. I also liked how foliage was rendered lighter than usual... Maybe I should expose some through an R72 filter...

There is no special mask-layer. The mask is integral part of the basic 3-layer set-up, in which couplers of two layers are coloured themselves. Such coloured layer is destroyed image-wise by the coupling action, by that forming two images within one layer.

(Very simply said and referring to modern films. The masking technique has a long story.)
