I'm using the impossible color film for SX70 and so far a lot of my pictures have come out with an orange tint which I can't figure out.
I made a test with 3 exposures, all in low contrast overcast natural light, I left everything on auto. I quickly put it in my pocket to shield it from light, as impossible instructs. All 3 turned out orange :bang:
Ideas ?
There's lots of good information on The Impossible Project blog site in the Tutorial section:

The Impossible films are quite sensitive to both exposure and temperature, both of which affect the color rendering and can lead to tinting. These two articles might give you some clues as to how to proceed:

I was having a lot of problems with the prints getting light-struck coming out of the camera, so I made my own "frog tongue" for the SX-70 series cameras by using a bit of artists tape and a cover sheet to create a hinged flap over the ejection slot. Now the print ejects under the cover sheet, and I quickly put it into a pocket or a bag to process for the first five minutes at least.
Overall, daylight exposures with the MiNT electronic flash or a FlashBar are more successful than just the auto-exposure on any given SX-70 camera, in my experience, and the MiNT flash unit includes a couple of color filters which can offset some of the Impossible film tinting.
The other amuzing game is that these cameras are quite old and have long since drifted from as-new specs in the metering system and the shutter timings. Each of my original SX-70s (and Spectras!) produce different results in the same light, with the same films.
That said, the slow speed at which the color film processes, the scant 3/4 of a stop exposure latitude, and the temperature sensitivity all together combine to make getting "normal" results pretty challenging. On the one hand, if I really wanted "normal" results, heck, I have plenty of cameras that do that really well. On the other hand, I would like
*some* predictability and consistency or I'm just spending too much money to not get the results I want. I've been talking with them about these issues and they understand, and continue to keep working on the film formulation. It really is an impossible project in many ways ... Fuji is not likely to give them the Instax film chemistry and you know where Fuji got that from in the first generation...
Because of the difficulties with the color process speed and exposure latitude, I've been shooting mostly Impossible B&W. It has more exposure latitude and less temperature sensitivity, and it processes more quickly by far (5-10 minutes vs 35-50 minutes).
It has cost me a bunch in film to experiment enough to get consistent and reliable images, but I'm getting to the point where I know what's going to come out of the camera when I punch the button now, and understand how the exposure and ambient temperature affect things. I'm more proficient at this point with B&W films and can use both SX-70 and 600 films (which have different response curves ...!) with results I like. Color is the next hurdle.
