The Rare Medium Method | Developing Impossible film in 10 Minutes

If you guys follow us and some on twitter (@snapitseeit)or follow anyone in the instant film community. You have heard of the latest rage in Impossible film research and development, you could say. Our buddy, all around epic dude, Polaroid mad chemist and owner of Rare Medium, (twitter @raremedium) has found a way to develop Impossible film under 10 minutes. Yes we are talking about any current Impossible film and no, we are not talking about the new Generation 2.0 film.

This is a pretty big break through and we have seen on twitter various times people say, “How come we didn’t think about this earlier!” They couldn’t be more right, but glad someone was crazy enough to try it! We discovered how to discover negatives the same way. With instant film, if you dream of something, try it,most likely it will work! We see people come up with the coolest things, and it all starts with a crazy idea.

Below is the video every one keep raving about! Even below that is a few rad tweets talking about peoples results with this rad new developing technique. Post your results on Twitter or Instagram using the #heatdev hashtag. We also plan to do a follow up to this post with peoples rad results! So, please submit your photos to our website, tweet us the flickr link or submit the image to our flickr pool! Please don’t forget to use the hashtag in your comment, with whatever method you choose!

  1. Since the initial video in this article I’ve dug out some older Impossible films I’d been saving (for some reason unknown). My appreciation for the newest formulations is growing, and just how far they’ve come. The older films are so sensitive to heat, in regards to tonal shifts. The newest films are so stable, even under this heating method there is very very little shift. The only changes I’ve really noted are evident when you don’t give the film at least 5 minutes (7-8 is better) to set. Why? Simply put we’re destroying the opacifier, that chemical layer that protects the film from light spoilage (remember those first generations? yeah that). When we kill that protective chemical too early light enters, and color gets shifted.
    For further fun, here’s another little video that I’ve used the method with a hot plate instead. Same results

  2. This is just a technical WordPress note, but you should be able to embed the Tweets if you have automatic embeds enabled by just pasting in the direct link. I think that makes it easier to read than blockquotes.

  3. this was an amazing tip. it worked very well on impossible project pz680 film.
