Are used to reduce the light intensity to prevent over exposure

can be carried out in trays, tank, or mechanized equipment

refers to films and papers that are composed of emulsion containing SILVER HALIDE crystals suspended in gelatin and coated on a transparent or reflective support

Designed to hold back the light and prevents halation.

Support the emulsion

it is the process of making a positive prints by projecting the negative images onto photosensitive paper.

are used to control the relative tone values in which colors are rendered by the photographic process, to lighten or darkened particular colors or to obtain color separation records for color photography works.

a photographic material exposed to such filtered radiation will receive a small amount of light than one without any filter.

you can change the appearance of the image by use of diffusers or patterns between the lens and paper.

Objects are distinguished from their surroundings by the contrast, which may be the result of a difference in brightness or color.

are similar in design and operation

an alteration in the spectral response of a photographic material brought about by a change in the spectral distribution of energy in the light source used for exposure is a difference in a relative brightness in which different colors are reproduced by the photographic materials

has a diffusing medium between the light source and the negative to spread the light evenly over the entire surface of the negative.

Also known as Printing in.

blocking a portion of the light when printing a photograph so that an area of the print will be made lighter.

are designed to show by direct observation the relative values in which color will be reproduced by a particular type of sensitized without or with a given filter.

is the deivice used to hold the paper during exposure.

contains silver bromide emulsion.Light sensitivity of this type is faster than the silver chloride paper.

is defined as the product of illumination and time.

made of gelatins or glass, are used in front of a camera lens to alter the color balance of light to change contrast or brightness, to minimize haze, or create special effects.

is the process of making positive prints by placing a sheet of printing paper in direct contact with the negative, emulsion to emulsion.

are used primarily to control light reflected from highly polished surfaces, metallic objects and others

A transparent Cellulose nitrate or cellulose acetate composition made in thin, flexible strips or sheets and coated with a light-sensitive emulsion for taking photographs

is the term used to describe the process of making positive images from negatives (and in some instances from film positives

conbines the contrast ranges in one paper, it uses a special Chlorobromide emulsion that produce varying contrast responses upon exposure to different colored light.

is made by passing light through the negative onto a piece of paper that is coated with a light-sensitive emulsion very similar to film

basically composed of a light-sensitive coating (emulsion) on a paper base or support .

removal of parts of an image in order to improve the image's composition.

this allows you to apply local exposure control to bring out more details in the highlight and shadow areas.

Part of the film or photographic paper which contains the silver grains that is sensitive to light.

the result of photography in its final form is the photograph

contains silver chloride emulsion, grained and produce deep black images, used for contact printing.

it has a set of condensing a lenses between the printing light and the negative.
