  1. Have been busy with shooting but thank you for the responses! In the end I did shoot it in red and I tried keeping in mind not going by false color. It wasn't a very significant scene but I really liked the results so thank you for input!
  2. Thank you very much for sharing! Needless to say we didn't have the resources to do anything like that. The scene from Joker was a big inspiration for a scene in our student shortfilm and we shot the scene yesterday! In the end we gelled our 4000k white flourescents with two layers of half plus green and one layer of full CTB. The other lights in the shot at 2100k. Camera set at 4000K. I was really happy with the results, thank you very much for the inspiration!
  3. I've geled the practical lamp in the shot and then boosting with a Skypanel out of frame. I'll be shooting on the Alexa Mini, ProRes 444, C-Log. It's the grading part I find most daunting. I'm not that experienced with grading so I don't know what I would need to so to shift the image to red in post.
  4. Would it be beneficial to shoot at daylight perhaps?
  5. But if I'm turning the green and blue values into red, will the information from the blue and green channels be retained? Will it not essentially be the same as just shooting red? I guess what I'm confused about is if I'm shifting it to red in grade then I'm taking out the green and blue values, so what would be the point in shooting it without the red color? Or am I misunderstanding how the camera shoots the image?
  6. I figure that was what I was doing already. The false color image from the viewfinder doesn't know that I'm shooting only in red, it just measures proper exposure. So if I was lighting with normal strength from the lights the false color would be showing a lack of exposure because I'm starving it from the blue and green channels. But because I've used false color for my exposure I've boosted the strength in the lights in order for the red channel to compensate for the lack of green and blue in the image, meaning the red has proper exposure.
  7. I don't like leaving decisions for later. I want red in the scene. Perhaps I could film it without the red gels, but what would a red LUT be doing exactly? How would I film it and how would I alter it in post to retain the color information of the blue and green channels while only promoting the red channel?
  8. By the way, those are mock-up sets. We are not done yet haha!
  9. Next week I'll be filming a short film and one of the scenes will be taking place in a corridor at a night club. We've been working with the idea of having one light at the end of the corridor makes all these silhouettes and then there's a small encounter happening in the middle of the corridor. (Drunk girl falls over, guy picks her up. Her friends come over and help her away.) I know red is a color that can look pretty blurry sometimes, so I was considering adding another light. Although, any light I tried to add didn't feel justified or ruined the look of the silhouettes which I quite liked. I also like to keep it quite dark, however in false color the skin doesn't even go green. Maybe I'm overthinking things but I was wondering if that was going to be too low. Anyways, I'm just posting hoping to get some general feedback! https://imgur.com/a/yzphd2G
  10. With any strength of the light? I was wondering what lumen value I should be looking for.
  11. Think I'll be shooting at 800 ISO at 2.8. Alexa Mini with Zeiss CP.2.
  12. I'm going to be lighting a bathroom scene with LED tubes over the bathroom mirrors. I will be buying these practicals but I don't know how to make sure I'll be getting enough light for them. The coolest tubes I could find was 4000K. I want them to give off a cyan look so I will be white balancing at around 4000K, then I will be gelling these practicals with a 1/2 CTB and a Half Plus Green. (I'll also be using some orange practicals so that's why I'm not white balancing at 3200K) Now seeing as I'm gelling these tubes with two layers I'm unsure I'll be getting a lot of light. 1/2 CTB has a transmission of 52% I think, and Half Plus Green has a transmission of 82%. I want the bathroom to be pretty dark but these fixtures will be the keylight. Not sure what stop I'll be using but possible I'll be around 2.8 so that I'm getting enough light. I don't know enough about lumens to know how to calculate how strong I need these lights to be (keeping the loss of light from the gels in mind). Could I have a hand working that out maybe?
  13. We've built the lamp and it works but the focus tube that goes through the umbrella moves freely. Meaning we couldn't find a way to lock it in place in the slot which obviously is a problem because when you tilt the lamp the whole tube and light house slides down. Does anyone know how to lock it in place, are we missing something obvious? https://imgur.com/a/kk8c7c0
  14. https://imgur.com/a/cTQon5n It's a mix of a warm color and green right? Realistically, if I were to film for this look, should I white balance so that the lights lean towards a orange-y hue and then increase the green in grade later? How would you go about achieving this look?
  15. Yeah I figure I could do it that way, but at the same time I want to learn how to use the tools of the trade. We're handed a budget (this is a film school project) so in kind of don't want to do DIY solutions if I can avoid it. Those solutions I can save for private projects! Thanks for the suggestion though. Meanwhile, just a curiosity. Does color shift if it's bounced off a white surface? Or will a white surface, being neutral, not affect the color of the light?
  16. Ahh that sounds reasonable. Do you know what strength I'd need for the plus green gel? We don't really have the budget to buy multiple rolls and we don't live near any place that sell them over the counter so there's no way for me to actually see it in person.
  17. Ohh hey, thanks for helping! Would be great hearing it from the source haha
  18. https://imgur.com/a/ydSrwOt I want the green of the bathroom with the warmth of the outside lights. If I white balance at 5600K and put the warm lights at 2900K or 3200K. Then I put a gel on 5600K lamps that shift them towards green. Would that do the trick? What kind of gel would I need then?
  19. I'm planning on shooting a scene where I cover the lens in a half plus green gel to achieve the look I want. What is the difference between doing that and changing the tint value of the camera to get a more green image?
  20. https://imgur.com/a/XWC16im Here are the pictures. Yeah, I'll try ordering 1/4 gels then.
  21. Apologies, wrote it in a rush. Basically I'm uncertain which gel I should buy to accomplish the look. The lamps in the garage have a temperature of 3600K. I figure that I'll need to white balance for a colder temperature so that the 3600K lamps in the garage appear warmer but I don't know which gel to buy to achieve that yellow/green tint from the lighting.
  22. I'm filming a scene in a garage and I want the lighting to have this kind of green/yellow quality. The lamps in the garage have a temperature of 3600k. I figure I need to make the lamps warm and then give them a green tint. So I'll try white balancing the camera at something like 4500k-5000k. Then I'll put a green filter in front of the camera. I was wondering if I should just for the 3600k filter or if there be some consideration to buying some other gel? I have this gel test sheet.
  23. I'm writing an essay in school about white balancing in digital cameras and white balancing with color filters. We want to establish why digital cameras have a native white balance and why a camera with a native WB of 5600k has more noise in the image when balanced for 3200k. I figured that we're talking about spectral sensitivity and that in general CMOS sensors are less sensitive to blue light. So when filming in daylight situations the sensor doesn't have to compensate the gain for the blue channel and thus not getting as much noise. Is that correct? Does anyone have a good source through which I can back these claims up, or if I'm wrong, what does control the native white balance?
  24. And that would create this kind of quality to the light? If I have som Kino Flos with 5500K tubes, could I combine gels to create that look as well? And if I were to buy practicals what would I need to think about? Because I'd prefer to have some in the frame. I live in Sweden so light frequencies can vary between Europe and the US from what I know. We usually film things in 25fps here with 180 shutter angle (what I've heard is that with European frequencies we need to use 172,8 shutter when we use 24fps). There's so many light tubes to choose from and many of them are LEDs now adays. I don't know what features I should be looking after to get the green- and cyan-tinted tubes.
