Question on Polaroid Type 55 film

[gr82bart]

Type 55 is the one that gives a negative and a print at the same time. Am I to understand that after developing, I should submerse the negative in water + PhotoFlo?

Nevermind. I found the answer - not PhotoFlo at all, but first a 18% solution of sodium sulphite and then a Hypo solution.

Hi Art,

Certainly not an expert here, but....when using 55p/n, I've usually put the negatives into a water bath to keep them wet until I can get them to a sulphite solution. I've never used photo-flo (although I see no reason not to) and I do wash them very well followed by a "hang-to-dry". The reason for the little tub of water is because I've usually been away from home when I've used the film and I can carry a bit of water in one of those snap-top Rubbermaid plastic containers that's about the same size as the negative.

cheers eh?

I clear my negs in sodium sulphite, wash then photoflow. no need to fix.

Hey Art,

Here's a thread you should read. Instead of using a half-ton of sodium sulphite, just use 25 ml/liter of Heico Permawash to clear the negs. http://www.largeformatphotography.info/lfforum/topic/501151.html

Several more valuable threads in the LF Forum for working with Type 55.

Cheers,
Alex

After clearing in the sodium sulfite solution, rinse for a couple minutes and place in a hardening bath for several minutes, followed by a thorough wash as normal. The type 55 emulsion scratches easily. The hardening bath helps toughen up the emulsion.

just an FYI, that negative will not fit a regular 4x5 print file selvee. Print File makes a version for that negative, and some negative carriers are difficult to use because of the size difference.
