Nick Centera Posted January 27, 2012 Share Posted January 27, 2012 Hey, I am going to be shooting an outdoor, on location, night scene. I will be shooting on 35 tungsten and was wanting to use HMI's to help with gaining most of the moonlight and also for the higher output of light. I do not want the scene to be completely blue so I was thinking of putting a slight CTO, maybe a 1/4 to help reduce the blue. I have read that it is pretty inefficient to CTO HMI's but I am not someone who likes to "fix it in post." Please let me know your thoughts. Thank you Nick Link to comment Share on other sites More sharing options...
M Joel W Posted January 27, 2012 Share Posted January 27, 2012 (edited) 1/4 CTO should eat almost no light. I think 3/4 CTO (which brings HMIs to 3200K) eats maybe 2/3 stop? Way less than CTB. If you're lighting ONLY with HMIs, this seems like something you could do in post very easily. There are other colors you could use, too. I forget what they used in Pan's Labyrinth but I think it was some sort of green/teal gel? Could be totally wrong but that looked great. HMIs vary pretty significantly in color temperature so you could easily have one at 6000K+ and another around 5000K. So some might need more CTO (and possibly some minus green) than others.
