Polaroid 55 versatility
How versatile is polaroid 55 pos/neg film. I recently purchased a box as a trial and have tested out on a still life indoors but wanted to know how flexible the material is. Can the tonal range of prints or negs be manipulated by development time/temp. Anyone tried this?
It is not tradition that secures the survival of our craft, its the craft that secures the survival of our traditions.
I don't think you can do much because it's either developed or not (as far as I've seen). I typically spot meter to ensure highlight detail is not blown, and so far that has worked very well for me.. (I make negs only)

As per Ansel Adams, and Polaroid's tech notes on their web-site, print development is time sensitive, there are noticable density changes in the print if one goes above or below the recommended dev. times.
On the otherhand, the negative density will not change to any noticable degree when over-developed, and in fact Adams recommends when shooting for the negative, to give it 1 minute to ensure full negative density.
Of course, your own time tests for prints will provide you with the concrete data required.

I'm sure that I've read somewhere that the negative portion of 55 film can be separated from the package without being run thru' the rollers and then developed in the soup of your choice. Just use an average time for iso50 film.

In my experience if you expose the film at an iso of ~25 you get a great neg and 50 gives you a good print. The way I rate the neg may say more about my preference in negs than true iso of the film.
In the Panatomic X thread one of the posts refers to the technique of exposing and souping the neg in darkroom.

This is what I've heard (read) too. I think Jim Brick of pure-silver mentioned this. It is essentially, very similar to old PanX film.

It works very well in D76, HC110, Microdol-X and the usual pyro developers. It does not do well in hangers since the film is not the same dimensions as 4x5 sheet films and is on a thinner support. When I had multiples to wash, it was my custom to take the scissors and trim a little to fit the hangers, but with the film being on thinner support it has the tendancy to come out of the hangers if the water pressure was a bit "too high".
I would also be interested in using type 55 film if the processing of the negative could be deferred. I read somewhere that this could be done but have not satisfield myself how, prior to buying a polaroid back for my Bronica SQ system. The data sheet for type 55 film and an on line description of the Polaroid back for the SQ does not make it clear how.
If anybody has pulled this off I would be grateful for feedback.
I haven't actually done it, but I have a Polaroid 500 holder (waiting for me to have a camera it fits) and have read about it. Delaying processing of the 4x5 Polaroids is simple -- after exposure, reinsert the cover sleeve to full depth and return the lever on the holder to the "L" for "load" position, then pull firmly on the same tab you'd use to process immediately. With the rollers retracted, the packet will pull out of the retaining clip at the bottom of the holder and pull out, in the same condition it went in except for the presence of a latent image in the negative.

You can delay processing of any Polaroid packet film this same way, but Type 55 is the only one that can be separated and darkroom processed to produce a printable negative...
Given the cost of the complete Polaroid, one is driven to wonder if Polaroid could be convinced to supply a "neg only" version of Type 55 -- it'd basically be an ISO 32 (or so) ready-load similar to the Kodak and Fuji products, usable in the Polaroid 500 (with care) and 545 family backs, with film similar in character to the old Panatomic-X. It *should* be cheaper to produce than the current product because it would require both less material cost (no chemical pod or print layer) and wouldn't require the "reverse in place" operation that turns the negative to face the print as you pull the tab -- so it should be less costly to assemble (though the economics of manufacturing would likely dictate that it's cheaper to use an identical negative layer and simply leave out the pod and print). Even if it costs more than Quick Load or Readyload, the unique film and the fact that exposure can be field checked, accurately, using a regular Type 55 would produce a market among those who commonly shoot 55 for the negative.
Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.
