Burning: a darkroom technique. To burn-in a print, the print is first given normal exposure. Next, extra exposure is given to the area or areas that need to be darkened. A card or other opaque object is held between the enlarger lens and the photographic paper in such a way as to allow light to fall only on the portion of the scene to be darkened.
Dodge and burn change the lightness of the pictures, inspired by the dodging and burning performed in a darkroom. Dodging lightens an image, while burning darkens it. Dodging the image is the same as burning its negative (and vice versa). Dodge modes: The Screen blend mode inverts both layers, multiplies them, and then inverts that result.
Before Photoshop, dodging and burning were used to lighten or darken a part of the photograph to get better details in highlights and shadows. [5] Toning changes the color of the photograph. Black and white photographs can be changed to sepia, red, orange and even blue. [6] Toning can be used to help make the photograph last long.
The exposure of the paper is sometimes modified in the darkroom by dodging and/or burning-in, further complicating the overall tone reproduction, usually helping to map a wider dynamic range from a negative onto a narrower print reflectance range.
Ansel Adams used darkroom exposure techniques, burning (darkening) and dodging (lightening) a photograph. [ 11 ] [ 12 ] Whereas manipulating photographs with tools such as Photoshop and GIMP is generally skill-intensive and time-consuming, the 21st century has seen the arrival of image editing software powered by advanced algorithms which allow ...

A positive image is a normal image. A negative image is a total inversion, in which light areas appear dark and vice versa. A negative color image is additionally color-reversed, [6] with red areas appearing cyan, greens appearing magenta, and blues appearing yellow, and vice versa.
