How about some infrared images

[StoneNYC]

Need to make sure of a couple things. The bellows must be IR safe and you will need an APO lens. The bigger format gives funny results with non APO lenses.

Yup, the lens will be one of the Fujinon C lenses (300 C, 450 C, 600 C all APO to my knowledge).

I've heard mixed info about the Chamonix bellows, Dan Bayer tells me he used the Chamonix 45N-2 with lots of EFKE820IR and never has had IR fogging, yet others tell me their bellows are not IR proof.

Maybe older models weren't IR proof and new ones are? Anyone?

Is duveyteen IR proof cloth? (Assuming it's thick enough).

On 4x5, the older bellows are IR proof. I believe the first 200 were IR-proof (I happen to have #198 ). Though from experience I discovered the film holder slits where the darkslide inserts are NOT IR proof, so I had bad fogging problems for a while.

I have no idea how that translates to the 8x10 model.

Just cover your bellows and film holder with your darkcloth and you should be good, maybe?

I'll have to ask I guess... Maybe if I'm ambitious I'll just set the camera up at night and inset a sheet of film in a 4x5 holder and leave it sitting in the bellows half open, then develop that night to see... Don't want to waste any 8x10 testing and I don't own any 35mm or 120 820 IR to test with

Unless anyone wants to send me a roll or two?

Why would you test for IR at night?

Sorry, I have to clarify, I don't own a dark room, and I do everything in my Dark Tent.

But my day by 10 camera will certainly not fit in the dark tent, the holders I can load just fine, but an actual camera, I don't think so, so the only way for me to get a 4 x 5 film holder inside the Bellows is to load it at night and then in the morning bring it outside to test it, but I couldn't actually close the holder dark slide and remove the holder to develop it until nighttime when I can get to a light proof space.

Make sense? If I had an 8x10 to 4x5 reducing back, this wouldn't be a problem...

Stone, just tape the film in the 8x10 holder.....

Neither my 8x10 or 11x14 standard bellows are ir safe. The 8x10 is about 10 months old. I bought leather bag bellows for both, which works well in the context of wide lemses.

WOW!!! $25/50 sheet box??? You made out like a bandit!

What ASA is it?

And care to share any? I'm building an 11x14 camera (better than my first camera which was only a pinhole) and I would love to shoot some when I know it's working!

I'm sure everyone asks you though, maybe if I offer you double your purchase price! Haha

Good luck with your 11X14 camera, but I am going to pass on selling the film. Kind of want to hang on to it as I still have a 11X14 camera and a few holders and may want to use the film one day.

Effective film speed with a 720 nm is slow, and even slower with an 820 filter. Think in terms of 5-10 seconds at f/16 in sunlight, assuming you want some detail in the shadows.

The bellows on my early Cham 8x10 is not IR safe. The bag bellows you can get for the 8x10 is IR safe.

Well I won't be using the bag bellows

I know mine is #145 in the updated model production line (when they added the bail back).

So I guess it's probably not old enough to be the IR safe version.

ALSO thanks for the taping the 4x5 or even 120 to the 8x10 good idea I feel dumb for not thinking of that! Lol.
