Olivier Metzler Posted January 24, 2021 Share Posted January 24, 2021 Hello everyone, I have a question about a BTS shot that I saw for a music video (here's the music video: https://www.youtube.com/watch?v=vlBKCwydtPY) The cinematographer was shooting at: 23.976 fps 180 shutter T/2.0 EI 800 ND 1.2 Now, my question is regarding the use of the ND 1.2. I understand the use of NDs in exterior locations or when trying to balance an interior with an overexposed exterior, but in this case, the music video was shot on a stage. And so I'm wondering why the cinematographer decided to use an ND 1.2 and shoot at T/2.0, instead of say, have the lighting set for a T/2.0 exposure without the need to use the ND 1.2. Thanks!

Then they just have to pull the ND out to be ready to shoot, rather than having to add more lights. Much faster, and makes the director and AD happy. 1 Link to comment Share on other sites More sharing options...
Olivier Metzler Posted January 25, 2021 Author Share Posted January 25, 2021 I hadn’t even thought of that, but that makes a lot of sense! Thank you! Would you foresee any other reasons why a DP would overlight then use ND to lower open up again, other than planning to shoot high-speed overcranked shots?

Sure, although most would involve changing the ISO/EI or shutter speed, or shooting on location. 1. Perhaps they are trying overpower the natural ambience or practicals in a location they can’t fully control. Say you want a contrasty look with dark shadows, but you’re getting ambient spill from a large skylight that you can’t black out or flag off. The spill is filling your shadows, so you overlight and ND down to increase the ratio between key and ambient fill. 2. Similarly, you’re shooting with fire fx and you don’t want the flames to clip, so you light up everything else to be within the same exposure range. ND just lets you maintain a shallower depth of field at higher light levels. 3. You want to cut the shutter to eliminate motion blur in a later sequence. Same idea as over-cranking, saves time re-lighting. 4. You want the artist’s eye color to pop, so you overlight to get their pupils to stop down. 5. It’s cold inside the studio, and you’re trying to keep everyone warm by turning on all the big tungsten lamps?

Olivier Metzler Posted January 26, 2021 Author Share Posted January 26, 2021 Thank you for sharing your insight on all this! And I'm sure it's been done before for those same reasons, but that last one made me laugh! Link to comment Share on other sites More sharing options...
Premium Member Satsuki Murashige Posted January 26, 2021 Premium Member Share Posted January 26, 2021 In film school, my cinematography professor ordered a few pizzas for the class and kept them warm with 2K fresnels. I always remember that! Link to comment Share on other sites More sharing options...
Olivier Metzler Posted January 26, 2021 Author Share Posted January 26, 2021 I wish I could upload this picture, because I literally did the same thing with a 2k Blonde during a night shoot a few days ago haha Link to comment Share on other sites More sharing options...
