   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. The Color Dodge blend mode divides the bottom layer by the inverted top layer. This lightens the bottom layer ...

   Originally, all Eastman Color films, ECN and ECP alike, were on triacetate base (no Eastman Color films were ever made on nitrate base), but recent practice has been for ECN elements to be on triacetate base, so these may be easily spliceable (using lap-type cemented splices, also called "negative assembly" splices), and for ECP elements to be ...

5. Digital compositing - Wikipedia

   en.wikipedia.org/wiki/Digital_compositing

   The input images are referred to as the foreground image and the background image. Each image consists of the same number of pixels. Compositing is performed by mathematically combining information from the corresponding pixels from the two input images and recording the result in a third image, which is called the composited image.

6. Phase-contrast microscopy - Wikipedia

   In its positive form, the background light is instead phase-shifted by +90°. The background light will thus be 180° out of phase relative to the scattered light. The scattered light will then be subtracted from the background light to form an image with a darker foreground and a lighter background, as shown in the first figure. [5] [6] [7]
