Depth of field using 35mm lenses

December 3, 2005 | Photos | By: Mark VandeWettering

This is kind of a crazy Rube Goldberg project for budding videographers: a scheme for creating depth of field using 35mm lenses. Most digital video cameras have very limited depth of field because of their relatively small optics and imagers. So what’s a person to do? Well, basically create a telecine like setup that uses a conventional 35mm lens which casts an image onto a ground glass screen, and then use the DV cam to video that directly with a macro lens. The ground glass in this setup is actually implemented using one of those plastic spacer cds and an old CD player (the moving screen hides scratches and blems in the “ground glass”). Kind of a neat project.
