Timing Lights or Printing Lights
These are the lamps of the contact printer at the lab. Their brightness can be controlled, which is measured in a scale of 1 to 50, 1 being the darkest and 50 the brightest. In color there are three lights used together: Red – Green – Blue. When working with negative it is worth remembering that the values are reversed: the brighter the light, the darker the print will be.
