HIGH CONTRAST - An image that is high in contrast (as opposed to a "flat" image), wherein the negative, slide or print contains a wide density range. HIGH KEY - An image that is mainly made up of light tones, which relatively few mid-tones or shadows.

High Contrast Highlights Small, very bright part of image or object. Highlights should generally be pure white, although the term is sometimes used to describe the lightest tones of a picture, which, in that case, may need to contain some detail.

High contrast images have a lot of black or white in them; low-contrast images have a lot of similar shades of grey. Film is generally able to record a greater contrast range (dynamic range) than paper on the whole.

High contrast developer - solutions used to produce high contrast images. High key - photograph which contains large areas of light tones, with few middle tomes or shadows.

For high contrast scenes having a 2-stop and 3-stop ND filter allows me to fit the dynamic range of the scene into a single image. They scratch more easily than I'd like, but I don't know of any better ND filters than these. Flash Cards ...

Lith film Very high contrast film, which gives pure blacks and whites and no grays. Lith paper is a very high contrast paper, though it does normally give some grays with all but the most contrasty negatives.

If you are in a high contrast situation with wide differences in lighting, you many find that not everything can be recorded the way you'd like to be able to, ...

As you can see a high contrast is in fact often more important than high resoltion because "washed out" colors are usually much less acceptable.

Compromising with High Contrast Light In this situation, the camera is not able to record adequate detail in both the brightly lit background and in the shadows.

Fuji NPZ is said to be better on high contrast lighting because of it's low contrast (portrait film), so you should try it. Warning: When underexposed 1 stop (1600) it gets grainy and difficult to color correct. Has 4th color layer.

Ambient light lowers contrast in brightly lit rooms so you need a very high contrast ratio for those settings. Brightness is specified by an ANSI lumens rating, with higher numbers being brighter and better for photos.

Low Key Low key pictures emphasize the black or darker tones, mostly with hard high contrast lighting being used. To create contrast, a relatively small areas are usually brightly lit. Jump to Top    Back to Previous Page M ...

A place along the edge, that has very high contrast, has been chosen. On the petal side of the edge, the tone is almost pure white. While the background side of the leaf is almost pure black.

High contrast indicates a large range of subject brightnesses. 2. Of film: the rate at which density builds up with increasing exposure over the mid portion of the film/development combination. 3.

Type 51, ISO 640 print, ISO 80 negative, black and white (very high contrast print, reusable negative) Type 52, ISO 400 black and white (wide tonal range) Type 53, ISO 800 black and white Type 54, ISO 100 black and white ...

Slow film has fine grain (and hence high definition), high contrast but low latitude. (Latitude is the amount by which a film can be over or underexposed and still produce a reasonable image).

In this procedure, devised by Berry27 and rediscovered by Rees,199 one soaks high contrast paper in developer and then exposes it under the enlarger.

The most noticeable thing about FromEx was the high contrast and saturation. Only a slight Cyan cast comparable to EZPrints and the Kodak reference print. The Auto Exposure test images looked fine.

High contrast ratios of 1000:1 and up in DLPs and LCOSs deliver accurate detail and render saturated blacks, while a ratio of 400:1 is standard for LCD technology and also can deliver the same attributes as a DLP's higher number.

Low contrast originals won't need flashing, but high contrast images will be produced too contrasty unless you fog the film to some degree. Slide duplicators are the most expensive method of getting duplicates.

With high contrast, change in the line width is minimized, even when illumination output energy varies, which typically leads to error, or exposure is uneven on a wafer.

A high contrast image has a narrow range of relative brightness values. As you increase contrast in an image editing software, the dark colors become darker and the light colors become lighter.

High contrast involves not only an extreme Brightness Ratio but also few gray tones. Low contrast has an expanded range of intermediate tones with limited pure blacks and whites.

A measure of the rate of change of brightness in an image; high contrast suggests content consisting of dark blacks and bright whites; medium contrast implies a good spread from black to white; ...

Purists state that exposure must be determined from the highlight area but if that was to be the case, in high contrast situations, the overall transparency would be dense and possibly unusable.

Low contrast images will have a narrow basis with many pixels stacked together in the midtone area, while a high contrast image will have high levels of black and white and fewer grays. RGB images have a separate histogram for each color.

-Posterization - photographic technique using a number of tone separated negatives which are printed on high contrast material. A master negative is made by printing these in register.

The disposable digital has the disadvantages of some digital cameras, including reduced dynamic range resulting in poor ability to handle high contrast situations, a small and overly sharpened image file, and increased expense.

Can be a complex subject! In simplest terms high contrast = high gamma and low contrast = low gamma, but there's a lot more to gamma than this. Gamma Correction ...

Condenser Enlarger An enlarger with a sharp, undiffused light that produces high contrast and high definition in a print. Scratches and blemishes in the negative are emphasized.

Use a low-numbered or soft paper with a high contrast negative to get a print that most closely resembles the original scene. Use a high-numbered or a hard paper with a low-contrast negative to obtain a normal contrast print. (see Multigrade) ...

Purple Fringing In digital photography terminology, purple fringing is an undesirable purple "rim" that surrounds areas of high contrast in a digital image. It's very obvious when photographing people against a bright (but not deep blue) sky.

This angle could result in high contrast images with short, dark vertical shadows. It is wise to not rule out top light for all situations. There are times when it is useful such as when capturing abstract patterns and repetition in nature.

I guess the picture was clearly over-processed to show the result in the small size capture. HDR can be usefull in some tricky situation (like high contrast) and can lead to pretty natural results far from the hyper tragical ugly pictures.

Light in photography may be diffuse or direct. Direct light, such as light from the noon sun, hits the subject from one direction. If you're looking for high contrast between light and shadows, direct light is a good choice.

Gamma . Measure of the amount of contrast in an image according to the properties of a gradation curve. High contrast = High Gamma and Low = Low.

Contact Screen: a photographically-made halftone screen having a dot structure of a graded density, used in a vacuum contact situation with a high contrast (litho) frame. Contiguous: Placed adjacently; one after another.

Gamma - A measure of the amount of contrast found in an image according to the properties of a gradation curve. High contrast has high gamma and low contrast low gamma.

Notice that the eye on the shadow side of the face has just a little bit of light on it. The silver umbrella has produced a relatively high contrast light, which has a wide spread reaching across the model and background.

The apparent difference in brightness between lightest and darkest areas of an image. Usually refers to the gradation between black and white. Fewer gray values are described as "high contrast." Many shades of gray is low contrast.

Once you have opened your photograph, use the magic wand tool (or your other favorite selection tool), to select the area you wish to spot color. This may take some fine tuning if your image is not high contrast.

Contrast The range of difference in the light to dark areas of a negative, print, or slide (also called density); the brightness range of a subject or the scene lighting. See also Density, High Contrast.

want more contrast, you can slide it past where the histogram starts, as I have done here. What happens then, is that some of the details in the dark areas of the image are lost, and it just becomes black. Which gives an illusion of high contrast.

disadvantage of composite RGB filters is that resolution is diminished: three or four elements of the array are used to capture one pixel. Software interpolation has to be used to fill in the gaps, resulting in coloured fringes around high contrast ...

The chromatic aberration tool set comes in quite handy when you have color fringing in adjoining areas of high contrast. The vignette control tool allows you to compensate for light falloff in the corners of your image.
