History

• Ektachrome was one of the best-selling slide films made by Kodak. The film has three emulsion layers: yellow, cyan and magenta. As time goes by and the slides are exposed to light from natural exposure or from projectors, the colors shift and the layers degrade.
  
  

Use

• This film is used by photographers who want to project their images on a screen. Prints can be made from the slides. The film is only manufactured for 35 mm film cameras. Film speeds are measured by ISO. As of October 2010, Ektachrome is available at 100 and 200 ISO. Higher film speeds have lower grain density, but react faster to light when exposed.
  
  

Considerations

• When shooting with Ektachrome, photographers can ask the lab who develops the film to make a CD of the frames, so that over the years, viewers can have digital copies of the slides that will not fade. Keeping the slides in the cases or boxes in closets or drawers will slow the aging of the film.
