Positive (photography)

The technique can illustrate emotions ranging from crowdedness, to power, to chaos, or even to movement in a photo.

Color transparencies are an example of positive photography: the range of colors presented in the medium is limited by the tonal range of the original image (dark and light areas correspond).

It is opposed to a negative where colors and luminance are reversed: this is due to the chemical or electrical processes involved in recording the scene.

When film was first made (mid-19th century), it used silver-plated copper sheets that contained three layers with light sensitive chemicals on them.

Other items used to create film included leather, paper, and glass sheets.

Example of positive photography: The jet and clouds crowd most of the image, removing most of the negative space, like the sky and Earth.
Example of positive photography: The leaves and stem are the subject of the photo and occupy most of the space.
