Film Vs digital affect when changing lens


I was wondering, If changing the lens in the middle of a shoot would it affect the film? I did this after deciding I wanted to change my lens and didin't know if it would affect anything so I immediately changed the film before I started taking pictures just in case. Ididn't want to mess up any photos. Also, same question when shooting digital, which I doubt with digital it should affect anything since it's on a cf card. I know this is for film and I added digital in my question, but I'm sure some of you shoot both like me.

Thanks

  Hi Jyan,
Most every film camera that provied a means to interchange the lens, particularly the 35mm camera, can have the lens exchanged in daylight without much danger of accidental exposure (fogging. Naturally, changing lenses in bright sun might present some danger. As a precaution, don’t point the camera so that direct sunlight is allowed shine into the gaping hole, during lens interchange.

A little trivia: The 35mm camera operates much like a cine (motion picture) camera in that the film is not protected by a light proof paper backing. All other roll film sizes have this paper backing used to protect against accidental exposure when outside of the camera and stray light coming from the rear, inside the camera.

The black & white 35mm film has a gray base not present in other roll sizes. This gray base provides some added protection from exposure from behind and when rolled up. All cine films and Kodachrome 35mm film have an opaque carbon black backing. This backing is removed during processing. This backing prevents exposure from light striking the film from behind. When tightly rolled this backing protects all but the outer turns from fogging. A cine camera with through-the-lens viewing is particularly susceptible to fog from light coming in backwards through the viewfinder so the black backing in needed.

Best of luck.

  The short answer is, yes, you can change lenses on an SLR camera without affecting the film, or the digital images already on your card.

  Thank You so much. Now , next time I won't get rid of a good roll of film.
I was shooting pictures for someone and din't want to take a chance since I didn't know. Now I do.

Thank You.

  Consider that the SLRs were made for just that purpose (among others)and changing a lens is no problem. Obviously, don't leave it laying around with no lens and don't take a chance with direct sunlight.

  Hello Jyan,

Digital shooters prefer NOT to change lenses..or do so as little as possible.
It has nothing to do with the memory card.

Dust can easily enter the camera with the lens off and eventually will find its way to the sensor..This really sucks..It can be cleaned, but what a pain.
I never change my lens outdoors..go to the car or someplace out of the elements.
