Hello everyone. I have question for the helpful people of this forum. Lets say i have a cool white LED light(≥6000K). As many of you agree this temperature is a bit disturbing for the eye.( At least to mine.) So, my question is which filter(s) should i use for to balance it to 5200K? Thanks for your attention.
Hey everybody, My name is Mike, I am an Electric and I will be gaffing for a short film. I have to recreate late afternoon light to shine through a window. My question is do I have a strong enough light source? My main light source is an Arri Tungsten 5k. The DP wants it about 20 or so feet away from the window. We are on the second story so the light will be on a stand about 16 feet high. The DP wants afternoon light (4300k) to shine through the bathroom window. So I will gel the 5k on a 4x4 frame with 1/2 CTB (4600K). He also wants some New Hampshire Frost on it. Using Arris Photometric Calculator I calculated the Arri T5 5k light source at: 21ft. Middle flood to give me a 3914 Lux. Aperture at F13.8 ASA 800 30fps Wikepedia says Lux for a sunset/sunrise to be 400,1000 for an over cast day, 10 000 for full daylight. My 3914 Lux does not take into account my 1/2 CTB gel and Hamphire Frost. So ultimately I am asking where my light is placed right now 20ft away though 1/2CTB and Hampshire Frost, do I have enough light or Lux to recreate late afternoon sun? Yes I can lower the aperture on the camera from the 13.8. Or should I rent a 10k. Keep in mind I only have one Grip to help me. Thanks a lot for any help in advance, it is much appreciated. Cheers, Mike
Hi guys, Trying to find what works best - to dial the colour temp manually on camera or use a grey card for each lighting condition (custome balance)? I have used both approaches before, my concern is that sometimes the lighting conditions are more complex, like when using combination of tungsten and kino flos, then what temperature do you need to dial? Is it better to balance it on the grey card at the spot where you'll be shooting? Thanks for your help!
Hi everyone! Im investigating solutions on how to light a 60+ street party (people sitting by tables under a tent without walls in the middle of a suburban street) from early dusk until nighttime. My main concern is kelvin, in camera and on the lights My strategy so far is to use 1.2 and bigger HMI lights (5600k) on background housing and gardens, to give depth to the pictures of people sitting at the table. For the actual table/people-lighting, I plan on using china balls from the roof of the tent, gelled with half CTB somehow, to end up at 4300K. Other paper/lamps and globes will be left at 3200, to give warm hotspots and bokeh around the set. In camera kelvin will then be set at 4300k The set needs to be quite clean of stands and able to shoot 360. The china balls will be a part of the decoration as well as main light for people around the table. Will be shooting on 4x c300 My main concern is that my background will still be bluer than I want it. This party should have a very warm feel to it. Am I better off doing everything except practicals and decor at 5600k and in-cam? Thanks for any input! Best regards Howard
