Wind On Film: Speedlights flash, the picture is taken, the film automatically advances, the shutter is cocked, and all is in readiness for the next child in the line. Similar cameras are available which operate with 35mm film. The smaller film cuts costs a bit but naturally the contact prints are not so appealing as those from the larger film.
If your Boat is moving, that motion must be taken into account in determining the actual wind on film. What you measure or estimate (except when using the Beaufort wind on film Scale) is termed apparent wind on film; the vessel's speed and heading must be considered to determine true wind on film.
At first the processing required complex machinery and precise control and, consequently, was done exclusively by the manufacturer. To answer the demand for a film the photographer could process himself, Ansco brought out in 1942 its Ansco-Color film, which was followed by Kodak's Ektachrome film; in both of these dye-couplers were incorporated into the separate emulsions.
