Thanks for the answers. Haha yeah not well lit in that way. But still it felt like a decent exposure when it comes to the skin. These were the settings (attached)
Yes! These conditions were extreme but it also happened when i filmed in well lit room. There was noise on a black t-shirt (see attached pic).
I really need Log because the clips are going to be graded to match other material already shot
The noise level when using C-Log on 5D mark iv is insane (in shadows, dark details)! Am I missing something here?
