The Sabatier effect, also known as pseudo-solarization (or pseudo-solarisation) and erroneously referred to as the Sabattier effect, is a phenomenon in photography in which the image recorded on a negative or on a photographic print is wholly or partially reversed in tone.
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.
The Thatcher illusion has also been useful in revealing the psychology of face recognition. Typically, experiments using the Thatcher illusion look at the time required to see the inconsistent features either upright or inverted. [7] Such measures have been used to determine the nature of the processing of holistic facial images. [8]
Type 2 photosensitive anodized aluminum is typically coated with a photo resist, which may be of either the positive or negative type. Exposure of the photo resist through a negative and its subsequent development creates areas on the plate that are either protected by the resist or exposed to the effects of the dye, bleach, or etchant that are ...

Apple unveiled its push into AI, Apple Intelligence, in June and announced new iPhones Monday. We still don't know when exactly the iPhone will have the much-anticipated AI features, though ...
Without filters, infrared negative films look much like conventional negative films because the blue sensitivity lowers the contrast and effectively counteracts the infrared look of the film. [ 13 ] [ 14 ] : 16 Typically, a red filter ( Wratten #25) is recommended as the best compromise, which removes blue wavelengths while still passing enough ...
