The alternative to a Timed Print, a one light is a print that has not been corrected shot by shot, but shows what all the shots look like with the same printing lights in contrast to each other. Sometimes this can be helpful to know the range of fluctuation in exposure and color. (But it is curiously common for a lab to do some timing, even on a one light print, at the change of locations, at the change of rolls, or if one shot is so drastically off from the rest and it would be practically unseeable otherwise.)thepolliofolioglossaryofcinematographyterms
