A negative
Film for common 35mm cameras comes in long narrow strips of chemical coated plastic. As each image is captured by the camera onto the film strip, the film strip advances so that the next image is projected onto unexposed film. When the film is developed it is a long strip of small negative images. This strip is often cut into sections for easier handling. In larger cameras this piece of film may be as large as a full sheet of paper, or even larger, with a single image captured onto one piece. Each of these negative images may be referred to as a negative and the entire strip or set of images may be collectively referred to as negatives. These negative images are the master images, from which all other copies will be made, and they are treated with care and handled with caution.

Negative image A positive image is a normal image. A negative image is color reversed image, so for example red becomes cyan (where cyan is the mixture of green and blue), green becomes magenta (where magenta is the mixture of red and blue), blue becomes yellow and yellow becomes blue. Lighter regions become dark and vice versa. White becomes black and black becomes white, light grey becomes dark grey and dark grey becomes light. In black-and-white photography the only colors are black and white and shades of grey. Complementary colors are pairs of colors that are in some way opposites of each other. ...
Cyan is a pure spectral color, but the same hue can also be generated by mixing equal amounts of green and blue light. ...
Magenta is a color made up of equal parts of red and blue light. ...
Negative film Due to happenstance, many photographic processes create negative images: the chemicals involved react when exposed to light, and during developing these exposed chemicals are retained and become opaque while the unexposed chemicals are washed away. However, when a negative image is created from a negative image (just like multiplying 2 negative numbers in mathematics) a positive image results (see Color print film, C-41 process). This makes most chemical based photography a 2 step process. These are called negative, films and processes. Special films and development processes have been devised such that positive images can be created directly from film, these are called positive, or slide, or (perhaps confusingly) reversal film (see Transparency, Black and white reversal film, E-6 process). A negative number is a number that is less than zero, such as −3. ...

C-41 is the name given to the process for developing a specific type of color print film used in photography and often to the type of film itself. ...
A single slide, showing a color transparency in a plastic frame In photography, a transparency is a still, positive image created on a transparent base using photochemical means. ...
Black and white reversal films - which capture images in gray scales instead of colour as in color reversal films - are less common than color reversal films. ...
The E-6 process (sometimes abbreviated to just E-6) is a process for developing color reversal (transparency) photographic film. ...
