Welcome back to Dr. Love’s Tips, our ongoing series in which Impossible USA’s Camera Resource Manager Frank love addresses common film and camera questions. This week: The Secret of the Ooze.
We’ve had some people write in recently saying they had a frame of film here and there occasionally with blue liquid ooze coming out of the back top of the frame.
This ooze is in fact the developer chemistry. It is stored in 3 ‘pods’ at the base of the film. It is this that actually gave instant integral film that fat border on the bottom, purely from a functional standpoint.
The reason the chemistry occasionally oozes out the top, is very similar to why you’ll get the ‘undeveloped patch’. You see, the chemistry is spread from the pods through the frame as the film passes through the rollers of the camera. Now the amount and thickness of this spread is taken to an exact science, however, there are always some variables that can affect this. If shooting in cooler or warmer temperatures, or from one camera’s set of looser rollers to another’s tighter set, this can affect the spreading thickness. Also, if rollers are dirty, this creates uneven spots of spreading on the frame, which lead to white spots on your photos, but can also unevenly distribute the rest of the chemistry.
Depending on the circumstances, you can either be left with insufficient coverage, and the ‘undeveloped patch’, OR you can end up on the opposite extreme,...Read All
