i have quite a large stash of this film and would like to attempt image transfers with it, but so far i haven't gotten anything close to usable. i'm pretty much using the same method as you would with transferring 669 film. searching the forums & the net i found references and links to instructions specific for 690 on the polaroid creative site but the page there seems to have been removed. anyone here have any techniques to share? anything radically different that needs to be done compared to 669?
