Hi All,
I'm trying to take some lofi shots with my instant cameras, I have a polaroid 670 and I have a holga with an instant back on the way.
Can anyone tell me if there are ways to add grain to the film? I know if you warm up colour impossible project film it's gets lovely warm purpley colours. Heat doesn't seem to treat the 600 B&W film the same.
What you are looking for is hard to get . You can get some special effects with some filters, or try to add some moisture on some UV filter and see what you get... But to get bigger grain in Instax films (in your Holga) - it is hard.
You can manipulate the film in many ways - but I think it will not increase the grain. Pushing or pulling will not make difference in grain size. If you are using normal negative, and then you enlarge 10x - you can see grain increase/change, but in instant print I don't think so.
About manipulation techniques on instant prints - I have seen on impossible page many useful tips.
