Safelight

A safelight is a light source suitable for use in a photographic darkroom. It provides illumination only from parts of the visible spectrum to which the photographic material in use is nearly, or completely, insensitive.

Design

A safelight usually consists of an ordinary light bulb in a housing closed off by a coloured filter, but sometimes a special light bulb or fluorescent tube with suitable filter material coated directly on the glass is used in an ordinary fixture.

Differently sensitised materials require different safelights. In traditional black-and-white photographic printing, photographic papers normally are handled under an amber or red safelight, as such papers typically are sensitive only to blue and green light. Orthochromatic papers and films are also sensitive to yellow light and must be used only with a deep red safelight, not with an amber one.Panchromatic films and papers, nominally sensitive to the entire spectrum, sometimes have a region of minimum in their range of sensitivity that allows the careful use of safelight confined to that part of the spectrum, e.g. Kodak Panalure panchromatic paper, tolerant of limited exposure to light filtered through a Kodak 13 Safelight Filter. Other panchromatic materials must be handled only in total darkness.

Plot

The film starts off in front of a truck stop where Vickie is getting roughed up by, Skid (Alejandro), her narcissistic pimp. Seeing this physical exchange-taking place, Charles, who had been working at the truck stop, comes outside with a bat telling Skid to leave her alone. Skid eventually drives off not taking Charles seriously due to his physical condition.

Charles (Peters) is a 17 year-old high school student who gets constantly bullied because of his physical disability, but finds solace in taking photographs. One day at school Charles’ teacher, Mr. Sullivan (Gretsch), announces that a photography contest would be taking place at the school. Intrigued, Charles takes a flyer.
