3200 Kelvin without the need for filters in front of the lens or in front of the light source.. . . It can also be used. With light sources, the color temperature of its rays increases to 3350 K without the need for filters in front of the lens or the light source, as long as the final correction in the colors of the positive image will be done during printing or enlarging. The following table shows the necessary filters when using other light sources.
