how to develop polaroid film negatives ?

[david_altmann]

i have some polaroid B&W film that i think has a negative. im not

shure but i dont have it at hand now.

 

im interested in how to process such a film. do i need a stop bath

too or just develop and fix ?

 

i figured this cost me the same per frame as shooting b&w film with

the rz plus proof prints. and i have instant results. (not as sharp

but anyway)

 

thanks, D.

I'm assuming Polaroid Type 55 P/N<p>

This will give you a positive, and a negative. The positive needs to be coated (product included in the Polaroid package) and the negative needs to be cleared in Sodium Sulfite solution (not included). I have never bothered getting sodium sulfite, but use Kodak Hypo Clearing Agent, which <i>is</i> mostly sodium sulfite, and easier to source.<p>

Theoritcally, all you do is clear the negative in the HCA, wash and you're done. I have heard of people fixing them... I think.

I've cleared Polaroid 55 P/N film in sodium sulfite only. No fixer is needed. There is no reason why the 3 x 4 inch negative should not be sharp unless the gear you are using is not very good.

hmm sounds complicating.

a friend used a ilford fix for that. but i dont know wich film he used or if it worked out.

 

James i use a polaroid magazine for mamiya rz. there always film flatness issues with pack film.

 

maybe you assumed i use single load large format polaroids ? that is something different i believe.

 

thanks for the answers, D.

If you are using Polaroid 665 P/N pack film, the same applies, an 18% sodium sulfite bath or, as Nikos suggests, hypo clearing agent. I've never found it to be complicated.
