Polaroid 8x10 from The Impossible Project

[babavaga]

Hello folks!

Recently I've tryed my first Impossible 8x10 polaroid. The result is far from stable and quolity is awfull, but I think it can be interesting.

First I made several tests by Polaroid Spectra and Impossible Cool Shade film



Then I've opened my last original polaroid 8x10 box and made a photo for compare to new one



and then my first Impossible Polaroid print 8x10



If it is interesting for someone I'll try to post more technical information and next shots.


P.S. for moderator - please move my post if You know what forum will be better

Would like to know a bit more about the differences in exposing the two 8x10 prints. The film is obviously different in ISO and one is color, the other B&W. Also, what processor did you use ? Motorized or hand-cranked ?

First film was ISO 80, but I've exposured it like 40. Also i've developed it for 90 seconds in 23C instead of 45 sec @ 20C. It is little bit underexposed.

The second time with IMPOSSIBLE I set up 640ISO and measured shadows using matt halfsphere of my Sekonic 758. It was f:18. Then I've measured different parts of an image:



It was f:18 set while exposuring this image.

I would like to share my post on result of this film. The tones of this film is very good with even emulsion spreading.



Camera: B&J field

I'm interested in giving this a shot -- does anyone know where I can find a manual (hand cranked) 8x10 processor and holder? I'm in NYC....

There is a youtube video here.

Some updates since I last posted.
I would like to share a video walkthrough regarding the usage of this film done up recently by a group of enthusiasts.

Thoughts:
Tonality is excellent when well exposed. The exposure latitude is narrow similar to slides. I rated the film at ISO 640 and shot with indoor halogen spot lights and the exposure was pretty spot on at this rated speed. The emulsion spread covers the entire negative when used with the Polaroid processor operated electrically without streaking. Price wise, it is as expensive as a sheet of Velvia 8x10 and may not last long if poorly kept, however I suppose the thought of an instant photo at the size of 8x10 is priceless.

Precautions:
Care should be taken to wipe off the excess goo (developing paste) at the sides and the end of the photo. At the same time the photo has to be peeled apart to dry completely especially in a humid environment. For the case of my humid country, Singapore, it took up more than 2 weeks. Some photos I shot had turned yellow as a result of not wiping the excess goo.
