With the passing of Kodachrome, I have, over the course of the last several years begun shooting d.....l for some of my color work. That said, for archival purposes, I have, when shooting subjects of particular interest, also often times shot the same image(s) on analog, specifically E100G and/or E100VS. My issue: Often times I may not finish an entire roll of film, so I end up rewinding the partial roll, making down the number of exposures, and reloading the film at a later date. Needless to say, this is an obvious nuisance; it is also wastes frames (a precautionary measure on my part). The question(s): Is is necessary to remove "professional" film from the camera if the film would otherwise sit in the camera for several weeks? Is there a limit to how long it would be safe to leave the film in the camera?
