Kodak 3412 ISO40 Black and White Negative Film (120 Format, Single Roll Trial) Thank you for your continued patronage. We have received feedback from customers regarding humidity, and we have developed new individual packaging with desiccant. This product is a trial offering of one roll of "Kodak 3409" (ISO16) black and white negative film for 120mm medium format cameras. ※ Sets of 3, 5, and 10 rolls are also available on My Page. Bulk orders are also possible, so please feel free to contact us if you are interested. 【Film Features】 Kodak 3412 was originally developed as a high-definition film for aerial surveillance, so it boasts extremely high resolving power. This product is a 120 format version of the long roll type 3412, re-rolled onto backing paper. The backing paper used is recycled from Portra 400, Portra 160, Gold 200, Ektar 100, etc. Therefore, the brand name printed on the backing paper is different from the film inside, but the film is all Kodak 3412. 【Development Notes】 This film requires processing with the black and white specific D-76 developer. It is different from the C-41 process (color negative development) indicated on the backing paper, so please be careful not to accidentally request C-41 development when ordering from a photo lab. If processed incorrectly in an automatic developing machine, it may lead to equipment damage and the possibility of being charged for damages. Please handle with care. 【About Film Speed】 The manufacturer's standard film speed is ISO40, but shooting at ISO25 to ISO50 is also possible. Please adjust the film speed setting according to your shooting environment. 【Condition】 Because it is DIY-packaged, there may be some scratches or small spots on the film surface. We store all films in refrigerated conditions and strive for quality control, but please refrain from purchasing if you are looking for perfection or are overly concerned about minor imperfections. Shipping Method We will ship via anonymous delivery (Yu-Packet Mini). This special film allows for long exposures even during the day due to its low sensitivity, giving black and white photography a new appeal. If you are interested, please consider purchasing.
