Negatives are normally used to make positive prints on photographic paper by projecting the negative onto the paper with a photographic enlarger or making a contact print. The paper is also darkened in proportion to its exposure to light, so a second reversal results which restores light and dark to their normal order.
A simple example of this is conditioned food aversion, or the aversion developed to food that has previously resulted in sickness. Food aversions can also be conditioned using classical conditioning , so that an animal learns to avoid a stimulus previously neutral that has been associated with a negative outcome. [ 3 ]
The edited original negative is then copied to create a safety positive which can be used as a backup to create a usable negative. At this point, an answer print will be created from the original camera negative, and upon its approval, interpositives (IPs) and internegatives (INs) are created, from which the release prints are made.

Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints.When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from ...
An example of digitization as part of a photograph preservation strategy is the photographic collection of the Tay Bridge disaster of 1879.

Only the positive prints survive, owing to the widespread practice of recycling the original glass negatives to reclaim the silver content ...

Exposure to a negative is typically done with an enlarger, although contact printing was also popular, particularly among amateurs in the early twentieth century and among users of large format cameras. Wherever the light strikes the paper the silver halides form small specks of silver metal on their surface by the chemical process of reduction ...
