Premium Member Charles MacDonald Posted September 6, 2007 Premium Member Share Posted September 6, 2007 can anyone please tell me what 'printing lights' means and how it is done? Short form, it is a way to express the exposure that the lab whould use to print your negative on a B&H Printer. Selecting the right "lights" is called "Timing" The lights are expressed as a whole number for each of the three printing colours. like 25 25 25.

Brian Pritchard Posted September 6, 2007 Share Posted September 6, 2007 Short form, it is a way to express the exposure that the lab would use to print your negative on a B&H Printer. Selecting the right "lights" is called "Timing" The lights are expressed as a whole number for each of the three printing colours. like 25 25 25. The numbers are obtained from a VCA, Video colour Analyser, and the numbers are fed to the printing machine by a punch tape, floppy disc or by a direct computer link. The three numbers send signals to the light valves in the lamp house telling them how much to open. You will find details of punch tapes and B&H lamp house on my website. http://www.brianpritchard.com/Model%20C.htm and http://www.brianpritchard.com/Punch%20Tape.htm I did post one of these links a week or so ago and apologise for doing it again. A well exposed negative should print at around 25 - 25 -25 although many labs have a setup that is slightly different from this. Brian Link to comment Share on other sites More sharing options...

Thanks for the kind compliments. I am always happy to help, I have been in the motion picture business for 45 years so if I don't know the answer I can usually find someone who does.
