Since Polaroid stopped making any instance films, Fujifilm also has discontiued its some of instance films as well, such as FP-100B45 and 3000B45. Now the FP-100c45 is the only one color instance film in 45 format. However instance films is now becoming more popular in some of the artistic purples.
The instance films used to be the one of the popular purples as a exposure tester, during three years learning in RMIT Uni., The Polaroid 55 and 664 would be the most popular films in my Photography courses, Unfortunately they have been discontinued after couple years.
Fortunately the FP-100c45 is still available on internet, it would be a opportunity to refresh my memory of my life in Uni.
This day, I tested Fujifilm FP-100C45 in a park by a Toyo 45a II with Schneider Apo-Symmar 210mm f5.6 L lens, the result looks pretty good.
