does this have slots in the side for the film or do i need hangers ?
Unfortunately no, the interior is not slotted. Use of this tank requires sheet film hangers (not included).
How does it work?
This item is a " Dip Tank ". You must place your exposed film sheets in hangers and then you move from tank to tank for each step of the development process. This entire operation must be carried out in complete darkness up to the point where the sheets are fixed and ready for washing. If you are not able to set up your operation in a totally dark place you might want to investigate using a drum type tank that allows for "daylight" processing of your film. Large format negatives, such as 8x10 are often processed in trays one sheet at a time. This is also done in complete darkness.
