Kodak 4127 film question

[Steve M Hostetter]

Hello,,,


Question about some out-dated Kodak 4127 8x10" commercial film,,
I'm on my way to Mich. can anyone tell me the iso film speed and if the recip times are the same as most B&W films..?


Thx
Steve

I understand the Tmax 100 is the replacment for this film.. So I guess I could use the Tmax data sheet..?

Steve, this is from my old Photo Lab Index. I'm not at work so I don't have access to a scanner right now. Monday will be the earliest. I can scan and email the data to you at that time but this should help you with exposures.

D ASA 50; T ASA 8
General properties: Medium speed , blue-sensitive films yield moderately high contrast and are for copying continuous-tone black and white originals, as well as for making positive transparencies or similar applications where red and green sensitivity is unnecessary or undesirable.

Reciprocity effect adjustments
Exposure time (seconds); Exposure Adj; Development Adj
1/100; None; 10% more
1/25; None; None
1/10; None; 10% less
1; None; 20% less
10; ½ stop more; 30% less
100; 1 stop more; 40% less

Hello Pat,,

So this is a medium speed film that you rate at iso 50.. ? And this is a positive B&W slide film ..?

I planned on using it as a taking film and not copy will it work well ?

Thx Steve

You can use it for general photography but red or orange subjects won't register on the film. Green may register slightly. Probably not the best film to use in daylight. For night photography, it may be pretty good if you're not shooting neon lights and such, where the colors would be a factor. It should make good transparancies by contact printing and development in Dektol 1:4 or so for about 3 to 5 minutes. Experimentation is key.

Glenn,,

Thank you sir for the info very helpful

[Steve M Hostetter]

If you were to use this film as a general purpose film what conditions would you use it in ...? something as monochrome as a snow scene ??

[Steve M Hostetter]

Thank you Pat and Glen..!

... Pat and thanks a bunch the the time involved giving that info ...!!

This will get me on the fast track to getting used to shooting B&W film and processing it as well,,,,,,,,,,,

I will post some shots as soon as I can learn how to process them ...

Thanks again

Ummm, if as your last post suggests, you're just getting started shooting b/w film, 4127 Commercial film might not be the place to start. That said, it was/is a film meant for graphic arts copy work, not as a camera film. (The reason EK suggested TMX-100 as a replacement was because that's about all they have left to offer- the two films are radically different.) Being sensitive only to blue light means that you'll have a 19th-century look to photographs made outdoors- high contrast and white skies. Since your film is long discontinued, I'd assume a speed loss, so I'd expose at a lower ISO than the data says, and develop in HC-110(D); perhaps less than the indicated time. That should bring the contrast down to reasonable levels.... this actuallly could turn out to be a fun experiment; remember that you can load holders and develop under a red safelight, which will make things easier.
