A rehalogenising bleach converts the developed metallic silver into silver halide. A fixer removes all silver halide by converting it into soluble silver complexes that are then washed away, leaving only the dyes. [10] The film is washed, stabilised, dried and cut. [11] In the RA-4 process, the bleach and fix are combined.
A bleachfield or bleaching green was an open area used for spreading cloth on the ground to be purified and whitened by the action of the sunlight. [1] Bleaching fields were usually found in and around mill towns in Great Britain and were an integral part of textile manufacture during the British Industrial Revolution .
Next, the film goes into the pre-bleach (formerly conditioner) bath, which has a precursor of formaldehyde (as a dye preservative) and EDTA to "kick off" the bleach. Next, the film goes into a bleach solution. The bleach converts metallic silver into silver bromide, which is converted to soluble silver compounds in the fixer.
Photobleaching: The movie shows photobleaching of a fluorosphere. The movie is accelerated, the whole process happened during 4 minutes. In optics, photobleaching (sometimes termed fading) is the photochemical alteration of a dye or a fluorophore molecule such that it is permanently unable to fluoresce.
Agfacolor. Ap-41 process (pre-1978 Agfa color slides; 1978-1983 was a transition period when Agfa slowly changed their color slide films from AP-41 to E6); Anthotype; Autochrome Lumière, 1903
The pre-bleach bath relies on carry-over of the color developer to function properly, therefore there is no wash step between the color developer and pre-bleach baths. [5] 6 Bleach bath Bath 5 6: 92–103 °F (33.3–39.4 °C) This is a process-to-completion step, and relies on carry-over of pre-bleach to initiate the bleach.
With light field photography, you don't talk about capturing megapixels -- instead, you're capturing megarays. There's no other camera to compare the first Lytro with, so the 11 megaray spec is a ...
A black and white photographic print in a tray while being processed after exposure to light under a photographic enlarger. Typically three trays are used containing either developer, stop bath, or fixer, in that order.
