	Latent image - Wikipedia, the free encyclopedia
		In photography a latent image is formed when light (or in radiography, X-rays) acts on a photographic emulsion.
		This image is invisible until the emulsion is developed using photographic developers, such as Metol.
		Under normal conditions the latent image, which typically comprises only a few atoms of metallic silver on each halide grain, is stable for many months.

	Photography - Wikipedia, the free encyclopedia
		The rayographs published by Man Ray in 1922 are images produced by the shadows of objects cast on the photographic paper, without the use of a camera.
		The first photograph is considered to be an image produced in 1826 by the French inventor Nicéphore Niépce on a polished pewter plate covered with a petroleum derivative called bitumen of Judea.
		Other factors are important in digital camera resolution such as the actual number of pixels used to store the image, the effect of the Bayer pattern of sensor filters on the digital sensor and the image processing algorithm used to interpolate sensor pixels to image pixels.

	Radiography in Modern Industry: The Photographic Latent Image (Site not responding. Last check: 2007-11-07)
		The photographic latent image may be defined as that radiation-induced change in a grain or crystal that renders the grain readily susceptible to the chemical action of a developer.
		It is interesting to note that throughout the greater part of the history of photography, the nature of the latent image was unknown or in considerable doubt.
		The simplest concept of the role of the latent image in development is that it acts merely as an electron-conducting bridge by which electrons from the developing agent can reach the silver ions on the interior face of the latent image.

	Charge latent image recording medium and recording/reproducing apparatus thereof - Patent 5055936
		An apparatus for recording an image as a charge latent image on a recording medium as claimed in claim 14, wherein said apparatus further comprises means for reversing a polarity of said electric field across said electrode and said auxiliary electrode means for erasing said charge latent image.
		The charge latent image corresponding to the optical image is therefore formed on the surface of the recording medium 1 facing the auxiliary electrode 9.
		It is effective for erasing the charge latent image to arrange the alternating power source 50 so as to control the voltage thereof being gradually reduced, and cutting off the applied alternating current when the polarity thereof is opposite to that applied in the case of recording, at the completion of the erasing.

	Howstuffworks "How Photographic Film Works"
		So, either manually or automatically, you now have an image that is focused on the film surface, and the proper exposure has been set through a combination of film speed, aperture settings (f-stop) and exposure time (usually fractions of a second, from one thirtieth to one one-thousandth of a second).
		There is a separate layer in the film for each color: Red light forms a latent image in the red-sensitive layer of the film; green light forms a latent image in the green-sensitive layer; blue light forms a latent image in the blue-sensitive layer.
		The image is called "latent" because you can't detect its presence until the film is processed.

	Charge latent image detecting device - Patent 5053889
		A device for detecting a charge latent image on a recording medium includes a photo-modulation member having a composite film of high polymer material and a liquid crystal material dispersed in the high polymer material, preferable liquid crystal material having refraction anisotropy higher than 0.18 and droplet size of less than 0.5 micron.
		Some charge latent image detecting devices used in such information recording and reproducing systems include a photo-modulation member which is opposed to a recording medium to undergo an electric field dependent upon a charge latent image on the recording medium.
		Since the polarization of the light beam incident to the analyzer 12 is varied in accordance with the charge latent image on the charge holding layer IL of the recording medium RM, the electric signal generated by the photo-to-electric transducer 13 represents the charge latent image.

	Latent image bleaching; selective latent image manipulation technique; the new Sterry method; contrastwise bleaching.
		Latent image bleaching has the opposite effect from bleaching a developed-out silver image—instead of increasing contrast, it reduces it.
		However, when bleaching a latent image (i.e., before development), the bleach acts selectively on the areas that have received the greatest amounts of exposure, which for a print are the low values (fls) and for a negative are the high values (the denser areas).
		Potassium ferricyanide typically acts as a contrastwise bleach with latent images in negatives and almost always requires the addition of potassium bromide for elimination of fog.

	photographic processing on Encyclopedia.com (Site not responding. Last check: 2007-11-07)
		Because of the reversal of dark and bright areas from the latent image to the visible image, the visible image is often called a negative.
		Toning is a process in which a photographic image is treated to change its color, as by changing the deposited silver to silver sulfide or causing a colored metal salt to form along with the silver.
		After this the latent image on the photosensitive paper is developed by a process similar to that used on the negative.

	SCAFO Online Articles
		The ability to enhance a marginal latent or even one that would normally be unidentifiable will continue to advance as computer software technology is applied in a manner similar to the way forensic light sources were applied in the late 80's.
		Image compression is normally done as a prelude to either image transport or storage.
		Lossless image compression preserves the exact data content of the original image, but because it preserves the exact data of the original, only a small savings in storage space requirement are possible.

	25 holography lessons (Site not responding. Last check: 2007-11-07)
		They form an ensemble of very small centers of latent image literally consisting of several silver atoms and these centers are located in the lattice defects of the crystal (dislocations) as in the potential wells.
		Moreover small centers of the latent image are strongly subject to thermal fluctuations of the lattice and can be simply destroyed in the course of time.
		By weak exposure of the silver bromide crystal the electrons knocked out by photons in small amounts don’t have time to create new centers of latent image but they are quickly captured by the centers of latent image already created by the first exposure.

	Print Solarization - Controlling the Sabatier Effect
		Those halide grains in the emulsion which have received a very high initial exposure will immediately form latent image specks on their surfaces and will be reduced to pure silver during the first development period.
		When these grains receive the second, or solarization, exposure, their internal latent image specks grow in size, but surface latent image specks are unable to form due to the migration of electrons and positively charged silver ions to their interior.
		During the first development these grains form surface (but not internal) latent subimage specks, which during the second exposure become surface latent image specks, allowing the entire grain to be reduced to silver during the second development.

	ElectrostaticPrinting
		A “latent image” (somewhat like a trace of the image) is created on a substrate which is later developed into a “full image” by attracting or repelling ink particles called “toners”.
		The latent image is then exposed to a liquid toner fountain where the latent image is developed.
		It is also possible with this printing method to produce images on different substrates by transferring the image produced on paper onto another substrate (i.e., film, textile, ceramic, etc.) by means of applying heat and pressure, a process known in the industry as sublimation.

	Process for forming slots of different types in self-aligned relationship using a latent image mask US Patent 4579812 (Site not responding. Last check: 2007-11-07)
		Thus, in the process of the present invention a latent image mask is employed which will harbor the images of all slot types and thereby produce self-alignment for the slot types as they are formed.
		The result of using the unitary latent image mask is that the slots of the first type are arrayed in self-aligned relationship with slots of the second type.
		The latent images can still be produced in one of the layers or can be produced in both of the layers.

	About Latent Images
		So the play on words is that this gallery is for images which come from within me--whether from dreams or my subconscious or just from some potential inside of me...images which once were latent.
		And the joke is that this is my latent image viewer--now you can see them...but only because this is their future and they're no longer latent.
		Some of these images are things from the past which I have scanned (so much of my past work isn't scanned yet) and many of these photographs are images I've taken recently with my digital camera.

		I’ve read that the latent image on cinematic film material is much more instable than what one might expect from still photography material.
		All my shot negatives had taken at least a week to process, ten days to two weeks in average, sometimes as long as six weeks; certainly, it was kept refrigerated in the meantime as far as I know.
		We are talking about a slow loss of the latent image which manifests as a loss of density.

	Basic Photography Tutorials. Latent image.
		The latent image is not visible, even under a microscope so the only way to tell if it is present is to chemically develop the film to reveal the image.
		During development the developing agent supplies electrons to the latent image thus attracting and neutralising silver ions to produce metallic silver which will eventually form a visible image.
		The latent image acts as a catalyst encouraging development to take place faster in exposed areas.

	A History of Photography, by Robert Leggat: LATENT IMAGE, The (Site not responding. Last check: 2007-11-07)
		The earliest exposures were very long indeed, and photographers would peer into the camera to inspect the image as it appeared.
		At the time it had been assumed that if the image did not appear, no change had occurred.
		Fox Talbot both independently and, it seems, accidentally, discovered that whilst short exposures produced no visible image, if one were to treat exposed plates with the fumes of heated mercury, an image would start to appear.

	The Daguerreotype and Development of the Latent Image: “Une Analogie Remarquable”
		There exists between these two results a remarkable analogy”. The relevance of this analogy made in 1839 is discussed with regard to nutgall gallic acid being the prototype developer of the latent image in photography established through the calotype technique of 1841.
		After 4 to 10 minutes, according to the period of the day, according to the season, and to the intensity of light, the image of immobile objects from which the lens receives the light, becomes perfectly imprinted on the plate, although this image is yet invisible and only latent [“seulement latente”].
		But this image, that is yet, so to say in a state of an unformed chrysalis, what consequently comes to reveal it out of its swaddling clothes? It is the vapour of mercury, from mercury heated to 60° Réaumur.

		For charged particle stimulation, OD would remain constant over the range of I. The process of development transforms the latent image into a visible image by reducing silver ions into twisted strands of metallic silver.
		The reaction is catalyzed by the latent image centers, and can be accelerated by the agents metol or phenidone.
		After developmment, the image is fixed with a thiosulfate solution, which forms complexes with undeveloped silver halide and hardens the gelatin within the photographic emulsion.
