Green screen should I shoot Tungsten or Daylight?

[Finner]

There are so many factors that you ignore but you're a god to yourself so you must be right.

Funny, your wife calls me "Oh, my God!" also.

Can we please keep the gods, wives and Doges out of this. I know it's fun but the topic at hand is dynamic range not domestic free range.

 

[Jason Sinclair]

Getting back on subject *cough*; Now with dynamic range all we can do is compare chart tests with 35mm chart tests if we are to compare and then the numbers matter. So if someone says the dynamic range is between 8 and 9 then what is films by the same argumentation of particularities? Is it 5 stops difference in people opinions or something less because my eyes are seeing something less.

Chill out you two!

You're both actually right. In general 9 stops is what I've found to be the usable range while keeping the shadow noise level in check at ISO 320. That does not mean there isn't any more range down there just that if you decide to use it you must trade off a greater amount of noise. This is less of an issue in daylight than tungsten, but I have shot a music video at ISO 640 that definitely had 10 stops of visible (Real world) range but was also much more gritty/grainy than I think Finner would accept. Theses are the trade offs currently. I will usually shoot at 400 ISO myself because a little texture doesn't bother me as much as a blown highlight.

I agree.

The two bickering children are both right.

I test both ways. I do controlled tests with charts. And I take it out in the field.

Both methods teach you something and are valid...

And BTW, the thread was about daylight vs. tungsten. I was going to suggest that if you're on a tungsten-lit stage, and you need some stop, then an 80D is a nice compromise. It only takes 2/3 stop away, and it's a -56 (I think) Mired shift which gets you from 3200 to 4000. If you can afford a quarter blue on all your lights then that helps too. But I've done two tungsten-lit greenscreen jobs so far with my Red, and the 80D seemed fine from a blue channel noise point of view.
Cheers,
Harry

Other than that, I have nothing to contribute... I'm just here for the take-away.
