  1. Ya I understand how variables effect the impact of different lights' outputs. Thanks On which factors to decide the baseline value (WB)?..for single source it may be easier to decide. But mostly I guess you are always using more than one light source, so whether day or night what are the factors to evaluate the decision of what to set as WB? and are there any common tried tested go to preferred values for shooting day and night scenes?
  2. Aperture balancing to certain value is called changing stops, but changing certain color temperature from one value to other value cant be called changing color stops?
  3. What would be the technical term to say changing color temperature values?
  4. Why not white balance 1 or 2 stop over to save the extra step of adding half CTO?
  5. May you please explain it more. CTO is the orange gel, so it will throw orange tiint..isnt it? so how will it show blue moonlight? Do you white balance your camera for night shots at 3200? and 5600 only for day shots? Also, if camera is white balanced at 3200, wouldnt HMIs will show blue light without help of any gel?
  6. Till now I have found 2 technical reasons to opt for 1.85 if one has to; 1. To fit the max size of cinema screens (i.e. if this is the ground reality that screens are of mostly 1.85 ratio..are they? 2. To use the max film negative area to avoid degradation of quality as one of the contributor mentioned in the comments. (Though with such High Tech DI services available nowadays would resolution even matter when image resolutions are already too high to worry about any kind of degradation cause of not using full area of film negative?
  7. It would be better to compare same scenes/compositions in different ratios
  8. So we can say that 1.85 is shot to fit the extreme size of most of the cinema screens without pillar boxing and letter boxing? Aint cinema screens mostly in 2.39 aspect ratio?
  9. I guess it was the other way around isn't it? 1.85 existed before 2.00:1, 1.85 wasnt wide and 2.39 was too wide, so Vittoria came up with 2:1
  10. Based on your given technical reasoning, may you please elaborate; 1. Why 1.85 is easy for Film Projection'? and 2.00:1 and 2.39 are not 2. Even if some directors likes to shoot on film, those films are later Projected in Cinemas Digitally, so what is the hindrance in shooting 2.00:1 or 2.39:1 to get the desired wider aspect which 1.78 does not provides, and makes hardly any difference in 1.85 so why not just opt for 1.78 if does not want as wide as 2.00:1 or 2.39? > This happens to be my original posted query to know the specific Technical or Creative reasoning to shoot in 1.8
  11. You mean the cinema screen sizes are 1.85 and that is why still movies are shot in 1.85 cause 1.78 will not fit the cinema screen size?
  12. That was the original question too, when it is already too close to 1.78 then what is the need to shoot for 1.85 for current age films
  13. Hi, 1.85:1 ratio is almost 16:9, so whats the need of shooting 1.85:1 rather simply shooting 16:9 ? Regards
  14. Hi, What are the Native Aspect Ratio of 35/70/Imax film negatives? Also, I read that 35mm negative aspect ratio is 2.39:1, so how does some old films have the ratio of 1.37:1? (which gives almost 4:3 image on 16:9 screen with pillar boxing but not sure if that's exactly 4:3) Regards
  15. Thank you, your DP pic is Florescent light on the background wall and LED or HMI at 5600 white balance camera? or is it tungsten white balanced camera with HMI in BG and tungsten on your face?
  16. Got it!!..so for most of the scenerios and to make it a habit, using Gels seems more appropriate.
  17. So what is the correct way?..use CTB on HMI or white balance your Digital camera on Tungsten?
  18. Ok thanks Phil, so if all HMIs are nearly 5600K that is white day light, then how does in most of the Hollywood movies in night shots blue light is shown by the use of HMI...is that cz of the use of CTB? is this possible for any HMI to generate blue light without CTB?
  19. Thank you Stuart for replying. Yes you are right about the Brute..I was asking something like that but bigger in size. Regarding color temp of HMI of different powers, are they all 5600??
