Omkar Bandiwadekar Posted August 26, 2018 Share Posted August 26, 2018 (edited) Hi,I had an opportunity to shoot a body builder for a short documentary/story.This was a guerilla and i was just packing 2 - 1x1 leds. I wanted to underexpose the shots to get that cut light to shape the muscles. The shots picked up a lot of grain in shadows losing detail This was shot with cine4 gamma black gamma range wide level +4 black level +2 color mode pro shot at 200-400 iso with canon 16-35 and 24-70mm on HFR mode. The editor was like these shots cannot be used. https://ibb.co/dTb5v9https://ibb.co/h5ab2phttps://ibb.co/fRpfTUhttps://ibb.co/h7C0TUhttps://ibb.co/cbBuoUhttps://ibb.co/jeAXa9https://ibb.co/fvo2a9https://ibb.co/iV5ha9 Do I need to expose the image normally and then bring it down in post? What am I doing wrong ? What do i Do if I have to underexpose properly in future. Edited August 26, 2018 by Omkar Bandiwadekar Link to comment Share on other sites More sharing options...
Stuart Brereton Posted August 26, 2018 Share Posted August 26, 2018 Some of the shots are a little noisy in the shadows, but that can easily be fixed in color timing. I'd say the editor doesn't know what he is talking about. Link to comment Share on other sites More sharing options...
Omkar Bandiwadekar Posted August 27, 2018 Author Share Posted August 27, 2018 Thanks for the reply.But these are the people I am dealing with.He also told me the detail is lost there and cannot be recovered(small patches of noise) Any advice as to how I can avoid it in future? Over expose then bring it down in post? or change my blacks?choose a different profile. Is this the same with ARRI and REDs? Link to comment Share on other sites More sharing options...
Premium Member Phil Rhodes Posted August 27, 2018 Premium Member Share Posted August 27, 2018 There's nothing terribly wrong with what you've shot. Silhouetting the subject against a bright window as you have in a couple of shots means you are quite dependent on shadow detail which is where the noise is most visible, but it's not the end of the world. One question worth asking is what sort of grading you would expect to be done on this material. Your camera setup suggests that you're going for a low-contrast original. I'm not sure if you're doing this because you want a low-contrast result or if you expect the material to be graded. Either is fine, of course, but be aware that the internal recording on the A7S2 is quite low bitrate and does not stand grading very well. If your editor is not expecting to do any grading or finishing work, you might want to ensure you're sending the pictures in a way that won't need further grading. Certainly the A7S2 is not a noisy camera at 200 or 400 ISO. It's just not a very good recording. P Link to comment Share on other sites More sharing options...
Premium Member David Mullen ASC Posted August 27, 2018 Premium Member Share Posted August 27, 2018 The problem is they are trying to dig up shadow detail when you lit and exposed it to not bring up shadow detail, so this is more of a creative control issue rather than a technical issue.

P The production house told me that material to be graded so i shot it accordingly,but talking with DI doesnt seem to be that experienced. The look I wanted was to just highlight the tone and shape of the muscles ,I lacked floppies and neg so i underexposed it. Link to comment Share on other sites More sharing options...

Yes Sir,but I wanted cleans shadows (shot it at 200 iso and HFR -100fps)it picked up lot of noise. So in future if I have to under expose with a A7s2(or any other camera) for such shots how do i go about it..expose it normally or +1 and bring it down in post or make some changes to the profile. Thank you for your responses *namaste Link to comment Share on other sites More sharing options...
