I was thinking in trying type 55, but I was going to the sodium sulfite. What exactly is the Hypo Clear?? Hypo Clear is a solution that removes the sodium (or ammonium) thiosulfate from the substrate following fixing. I clear my negatives with PermaWash, which is a commercial solution used to wash prints. Of course, none of this has anything to do with the original question, which had to fixing the negative. As previously stated, I do not believe that fixing Type 55 film is necessary - I have numerous old negatives that have simply been cleared and dried.

What exactly is the Hypo Clear?? Thanks António Vieira Antonio, Hypo Clear, or HCA (Hypo Clearing Agent ) is a product made by a couple of companies that I am aware of, there may be more, if anyone else knows of the companies , please feel free to chime in here . Kodak makes one, and another brand is called Orbit . Hypo Clear is a product to be used after the fixing step and a water rinse has been completed , it shortens the washing times needed for films. I use it for sheet films as well as roll films. My practice using Hypo Clear , is to use it with my Polaroid Type 55 positive/negative films, I put the negative in a 4X5 film hanger, and dunk the film for as long as it takes to get the developer gunk off the film, usually about 2-3 minutes at the most, I then wash the negative as I normally would any negative , and hang to dry. Am not sure where you are located Antonio, but if its the United States, you can get Hypo Clear at most any camera store, or order it online from www.bhphoto.com . I just looked at the Orbit bath instructions, and they say, to use 4 ounces of concentrate to a gallon of water , agitate for 30 seconds , and wash for 5 minutes . A one gallon working solution can do 80/8X10 (double weight) prints , or 150 sheets of 8X10 film . So you can see it is quite economical . Orbit is made by a company called TKO Chemical Co, in St. Joseph , Missouri , USA. price is about $10.95 USD per pint .If you order Hypo Clear from www.bhphoto.com, I would suggest getting a couple bottles or more, at time of ordering . I know the instructions on Polaroid Type 55 call for clearing with Sodium Sulfite, and I too wondered about using it when I posted my question similar to yours. Since I did not use Sodium Sulfite, I can not speak to the results . It seems to me someone remarked that using the Sodium Sulfite produced a higher grain , than just using a Hypo Clear. Some one correct me if I am wrong here . I started with the Hypo Clear ,and have the results I like, so have just continued with it . Kodak Sodium Sulfite sells for about $9.00 USD in granular form I know, but thats the extent of my knowledge using it for Type 55.

Antonio Hypo Clearing Agent is the Kodak brand of Permawash... Its what you use to remove fixer shorten wash times. andy ... If you are using Polaroid Type 55 film(BW) , you can do a couple of things, if you overexpose by one stop , you will get a lighter print, but get a bit more dense negative . If you are in the field , you can put the neg into a zip lock baggie filled with water, and clear the negative with Hypo Clear once you get home .

Thanks António Vieira http://www.livinginabox.net Polaroid instructions say you use Sodium Sulfite, but I once posted the same question on this list and couple others , and the consensus was to use Hypo Clear , wash, and hang to dry . If you are just looking to expose Type 55 to get a good print, that is usable for scanning and Photoshop , then stick to the EI 50 indicated by Polaroid, if you want a denser neg for printing , then use an EI of 25 . I use Type 55 a lot with my Santa Barbara Lensless 4X5 wide angle (2-1/2 inch fl ) and use exposures of about the 3-4 second range as a starting point , fine tuning if need be from there . ___ Post to the list as PLAIN TEXT only - no HTML Pinhole-Discussion mailing list Pinhole-Discussion@p at ??? unsubscribe or change your account at http://www.???/discussion/
