How about some infrared images

[Paul Cunningham]

Is there some fog due to the film or holder? The raw scan of the maui shot seems to indicate some extra magenta around the edges?

I've noticed this too, of course. I'm not sure of the source, but I will be monitoring. It definitely is older stock and not perfect.

I wonder how this would look cross-processed into C-41 and then printed?

I know it can be processed C-41, are you suggesting that as a way around scanning, that is, just go direct to print? One would have a bit less control, of course.

I am jealous you have some of this, it's not common. cutting down the thin roll film must be a bit of a pain in the ass too... ;-)

I'm planning to offer a few sheets of it, I think, but not sure what the price would be. Cheers, Paul

Paul, keep me in mind if you do offer some for sale. I would probably be up for a bit. Cash or trade of other interesting 4x5 film might be an option?

I was thinking cross-process in C-41, mostly for personal convenience, as I am all set up for developing C-41 and printing RA-4 at home, but not E-6 currently. I know the colors and rendition would be different than C-41 but this is not a film where color accuracy is all that critical to begin with. ;-) Wild colors are probably expected...

thanks for sharing your results! I'd suspect the holders of fogging possibly, since it seems to be on all 4 edges of the film - if it was fogging of the film while in roll form, it would probably only be on one or two of the edges, rather than all 4... just a random thought.

anybody use this type of film?

[Paul Cunningham]

I'd be curious to see the sensitivity curve.

That's RED sensitive not INFRAred sensitive. Big difference.

That's RED sensitive not INFRAred sensitive. Big difference.

One does not preclude the other.

One does not preclude the other.

Actually it does because it says right on the box that it's daylight loading with a green filter, which means it's not sensitive to any other light that would pass through a green filter including IR.
