pushing/pulling polaroid film

[wonderlustking]

is this possible? has anybody experimented, and what were the results. examples would be awesome

The Impossible Projects newest PX70 film has a slower ISO than what the camera was designed for and needs to have the light/dark wheel cranked all the way to lighten.

But as far as I am aware the Fuji pack films are self terminating. So you couldn't do much to them. But then again none of this is concrete evidence and I have seen crazier things done.

with 55 i did it all the time, as i wanted the negative to be the final product not the print that just came along for the ride , "so to speak"

How did you do it? The negative is ISO 25, and the print 50. If you exposed for the neg, you overexposed the print (and vice versa). By itself, that is just an exposure change, not a push or pull. How did you alter processing to push and pull?

i changed the time. i was only interested in what the negative would give me not the print.

It has been awhile since i used that film, may even 5 years, so i don't remember what ISO I used, but i never used the suggested times for allowing it to develop..

Do you know how the change in development time changed the negatives, Ann? It's obviously too late for this to be practical information, but I am curious.

similar to underexpose over developed, added density, or at least I thought so at the time

I had similar results a couple of years ago with a box of 55. The prints always came out a little light as I processed for the negs. I underexposed a couple of sheets and, instead of a 25 count, I gave it 40 before pulling. Got a couple of really nice negs from the end of the box that way.

Is there a way to expose fuji pack film so that you get a good negative?

yes, obviously there is. I haven't tested it yet, but please have a look at this:

as far as I know it only works with colour film.
