What is Halation?
Halation refers to the spread of light around bright areas in the picture, usually in the photo. The term is sometimes used in the context of movies and television. As a result of the repository, the overall image has blurred essential quality. This phenomenon can be very unpleasant for photographers when it is not desirable, although some intentionally try to achieve a certain appearance. A number of things can be used to create accidental or deliberate drive. When the emulsion is revealed sensitive to the lights, the light passes through the emulsion and then bounces back and creates a blurred halo around the areas of special brightness. Many film companies fought that later in its film it includes antihalace to avoid this scattering of light. When the film is processed, this layer is washed out so that the film develops normally.
Some amateur photographers with Otice with halalage when they have their film developed as a Quickie Laboratory, or using disposable cameras. In spite of the temptation to blame the laboratory staff for the problemM is actually caused by a film, not a staff. Other problems such as scratches or fogging film can be safely accused of photo laboratory, because these are indicators that the film was poorly treated with how it was processed.
When a photographer intentionally wants to create Halation, it is often done through the tricks of lighting. This can also be achieved in the Dark Chamber, through special handling of the film and developing paper. When Halation is truly desirable, the photographer can control the effect and create a softened and blurred look that is often popular for photos. Experimental photographers also play with Halalaca. The deliberate introduction of harassment in the picture can often be a quite striking unforgettable scene.
The film package will usually indicate whether the film has an anti -altitude layer in the area with general technical specifications of the film. Photographers,who want to explore this phenomenon can buy a film without this protective layer, even if they may want to experiment with several different brands and compare them. Many films manufacturers create lines of film with this layer and without this layer, because there is a popular demand for both styles. Of course, photographers who fought with Halation should choose a film that includes this layer.
