In simpleton terms.....how does the picture go on to a negative in the camera?(35mm)?

Answer 1

When you push the button, a little window on the camera opens. Light reflected off the subject comes in the window and makes an image on the light sensitive film.

When the film is developed, the image is made permanent. Then prints can be made from the negative.

Good Luck

Answer 2

The film has chemicals in it that are sensitive to light. When light comes in through the lens, it hits the film and changes the color of the chemicals at that place in the film.

Let's talk about black-and-white film first because it's simpler to start that way. For black and white film, the intensity of the light that hits a given spot of film will make the chemicals there turn dark; brighter light means more of the chemicals turn dark, so the negative is darkest where the original image was brightest, and clear where the image was darkest -- it's kind of like getting a sunburn through a lace top: the pattern of the sunburn is the reverse, or negative, of the fabric.

Later, when you make a print from the negative, the situation is reversed: you place the negative (after it's been developed) in the printer, put photographic paper under the negative, and then shine a bright light through the negative. THIS time, the negative blocks out the parts that were dark in the original image (because it's a negative image) and lets the light shine through the parts that were brightest in the original image (because that's where the negative was darkest).

The result is a piece of paper with dark places where the image was dark and light places where the image was light.

Color works in much the same way, but the chemicals in color film are sensitive not only to the intensity (brightness) of the light, but also to its color. The colors in negatives are "backwards" because the printing process works the same way as for black and white: you put the negative in the printer, shine a light through it, and the negative "absorbs" the opposite of the light you want in the final print.

So when you take a picture, the sky looks orange in the negative because all the orange will be filtered out of the white light that shines through the negative; the result is that only blue gets printed on the paper. A really dark orange in the negative will block out most of the light and only allows a little bit of blue to go onto white paper -- so you'll get a pale blue sky in the print, just as if you draw lightly with a colored pencil. And dark green trees show up as a light red in the negative, which will block out only a little bit of the red from the light, with the result that a LOT of green gets printed onto the paper -- like pressing hard with a colored pencil.

(Digital cameras work completely differently, but let's keep that a separate discussion to avoid confusion...)

Answer 3

The plastic (acetate) strip of film is coated with a light-sensitive gel called "emulsion."
The image from the lens is projected onto the emulsion during the time the shutter is open. The emulsion, which is composed of millions of microscopic grains of silver halide, then holds it as a "latent" image.
When the film is dipped in a bath of developer (processed) the chemical in the developer reacts with the grains that make up the latent image. Grains that were hit with bright light turn black, and stay attached to the acaetate strip. Grains that were not hit with light (such as in a shadow area of the image) are washed away by the developer. Then, you fix the film (in a chemical called Fixer), so that the grains of emulsion are made permanent, that's how you get a photographic negative.

And, to Gabe: a shutter is not called a "thingy." It's proper name is "doohicky." LOL

Answer 4

Photographic film is a thin plastic film coated with an emulsion made of a silver salt (silver nitrate, sliver halide, etc) that is sensitive to light. When light strikes the emulsion - when you snap the pic - the light causes the silver salt to change to elemental silver and darken. This is called the "latent image". Developing speeds this process up and then another step removes the unexposed/undeveloped silver salt leaving just the darkened part that was exposed to light - the negative.

Answer 5

in the simplest terms, the negative is coated with stuff that will change when light falls on it, when you press on the shutter(that's the thingy that opens and lets in the light in the camera, on to the negative) the negative captures the light image( but this is too faint to be used) then you develop the negative(to increase the effect that the light had on the negative and to fix it in place) but the colour is reversed so you print it on to the photgraphy paper to get it back to what we can see. i hope that this is siple enough and that it helped you understand.
