ABSTRACT

Varicon A camera accessory used toJmh and reduce film image contrast; it accomplishes the same purpose as laboratory post-fogging but with greater consistency and predictability. The Varicon, manufactured by Arriflex, represents a significant advance over the bulky Lightjlex, which was the first such apparatus to find wide use. It sits in front of the lens, mounted on the rods of the camera’s matte box, and consists of a clear glass plate encircled by eight 6 volt halogen lamps. The lamps are powered by two 12 volt batteries or by a 12 volt uc/dc power supply. The lamps emit light onto the glass flat, called the emitterplate, causing it to glow evenly. It brings up the light level in small enough amounts to bring up only the low-exposure areas of the picture, effectively flashing the film while the image is being recorded.
