How is the reverse film effect achieved with old film cameras?

I know that in digital it is all done in the editing program afterwards, but how did they do it with the film cameras? By reverse effect I mean making what you shot go backwards. I think there must be a manual way thats done actually on the camera.|||Are you talking about motion picture films?





If so pro level motion picture cameras have a reverse function in which the film is run forward to the desired length (unexposed) then the action was recorded as the film was shot backwards. Think of the old Erroll Flynn movies with the arrow hitting the bullseye. The arrow started out in the bullseye and was pulled out via a monofillament (fishing line) and then the film was flipped over so it looked like the arrow was shot into the bullseye. Remember this was a series of still images in sequence. The film was printed through the base side, rather than the emulsion, for this effect. Some bolex 16mm cameras have this function, as do most Arri and Eclair 16 mm. All 35 mm motion picture cameras have this capability.





If you are referring to stills, then you just flip the film over and print the pic as fhotoAce said.|||No, the negative or transparency has to be placed in the enlarger backwards. Instead of emulsion to emulsion, it would be placed so that the base of the film faced the emulsion of the paper





Or you could shoot using a mirror.|||OMG! Im so proud to be able to answer this question! I feel proper smart (I learnt it yesterday in my photography lesson)





When the camera takes the shot, it is taken in negative. This is because inside is a light sensitive film, and the camera is taking in light that is bouncing off the object and the light 'burns' the film, leaving. This means that the lightest bits burn the film more, and so the subject's (the thing you're taking a picture of) lightest bits turn dark on the film, and the darkest bits, where not much or no light is bouncing off, don't burn the film as much leaving it clear (because the film is clear).





The reason that you get a positive image when you get your film back from the developers is because of the development process. This includes placing the film against some light sensitive photo PAPER, and exposing it to light for a period of time. When light hits light sensitive paper, it turns it black, and so when the film with the negative image on it is on top, the black bits that have been burned on will block the light (because black absorbs light), and leave white, and the opposite with the other bits, they'll stay white, or only go very slightly grey because there arent any burt black bits on the film to block the light. So you can see why the developing process turns the image to positive from negative.


Then they just put the paper into an acid called 'developer for 2 minuites, then stopper (which stops the developer from developing) for a few seconds, then finaly in an acid which protects and 'seals' the paper so it doesnt get exposed any more when taken into the light.





I'm not awfully sure about how they do this with coloured images, but I imagine it's along the same lines..





If you mean movie cameras, then i think they just roll the tape the other way... Don;t really know much about that though..





:D|||Create a print normally from your neg. Once you have the print get a second piece of light sensitive photo paper and have the light sensitive sides facing each other and place it under the enlarger.


With just a white light expose the back of the first print for a longer period of time than you initial exposure. This should make a negative print of the original print on the paper underneath.





I was assuming what you meant by "making what you shot go backwards" you meant a negitive.





Note


When talking about reverse film, photographers use that term for a type a film known as color reverse film or color slide film
