orthochromatic film การใช้

• In her street photography Blondeau would often use orthochromatic film to make prints.
• She experimented with color printing, multiple exposure, orthochromatic film, and contact printing.
• Orthochromatic film remained dominant until the mid-1920s due to Kodak's lack of competition in the panchromatic market.
• Under his leadership Kay's went from being a processor of orthochromatic film to a sophisticated processor of colour film.
• The top layer's colour is light-safe for orthochromatic films ( which are sensitive to blue light but insensitive to red light ).
• Orthochromatic film proved troublesome for motion pictures, rendering pink skies as perpetually overcast, blond hair as washed-out, blue eyes nearly white, and red lips nearly black.
• If the red channel is eliminated and the green and blue combined then the effect will be similar to that of orthochromatic film or the use of a cyan filter on panchromatic film.
• "Moana " is thought to be the first feature film made with panchromatic black-and-white film rather than the orthochromatic film commonly used at the time in Hollywood feature films.
• This will, however, require longer exposure ( and change the resulting image ) . ( This is only true with panchromatic black-and-white film, since orthochromatic film is already sensitive to only a limited spectrum .)
• The old orthochromatic film stock of the early days was less discriminating about a person's color, as were black and white stocks in general, permitting some African-American actors a break, as their " color " was washed out or less obvious when photographed in black and white.
• The progression of lens design for later emulsions is of practical importance when considering the use of old lenses, still often used on large-format equipment; a lens designed for orthochromatic film may have visible defects with a color emulsion; a lens for panchromatic film will be better but not as good as later designs.
• The strips would be adhered to a board, usually a stiff white paper on which the artist would draw the publication's margins and columns, either lightly in pencil or in non-photographic blue ink, a light cyan color that would be ignored by the orthochromatic film used to make printing plates in offset lithography.
