FS7: 100 or 109 IRE gamma ?

[Lenilenapi]

If you don't even have time to check zebras on skin tones you're moving too fast for your own good and bound to make mistakes that are not fixable well in post. I actually can't imagine working that fast, though sometimes yes you have to wing it but by then you should have looked at zebras on face tones enough to know you are in the ballpark with your VF. HG7 or 8 would be fine for what you're describing.

I am curious about what people think the best gamma would be in a shooting situation similar to news shooting ie no time to pull out gray cards, no time for zebraying skin tones, etc, but where you would have all the time you need to color correct in post. For example if you would do a documentary on some war front, or covering some riots, or whatever. .

Choosing a gamma mode should not be based on how sloppy you're going to be with exposure. In other words, no matter which gamma you choose . . . exposure always matters! But with that said, Hypergammas that go to 109%, S-LOG 3, S-LOG2, and RAW allow the most flexibility for correcting exposure mistakes in post -- in that order. The standard gammas and hypergammas that clip at 100% are the worst possible choices for fast-moving shooting and require extreme accuracy. And besides that, setting an accurate exposure with with any of the gamma modes ought to bb fast and easy in almost any situation if you know how to use zebras properly, so the speed of the shoot should not make difference in the technique used or the chosen gamma.

I'll ignore the really bad advice about exposing for skin tones until another thread.

Listen to Doug on this one. You can tie yourself up in knots 'researching' and using other posts on other places about methodologies, but if you just want to shoot and get it right what Doug has just posted above is about as solid a piece of advice as you'll get on the subject.

Yesterday night, partly because I wanted to get out of my head a mental association, coming from nowhere I know, between the name "Doug Jensen" and the image of poker player Doyle Brunson, I typed "Doug Jensen" in google images and landed on Doug Jensen's site. I liked very much the animal shots from the newsreel.

I really would like to know what a good way to expose quickly and correctly with hypergammas would be. I guess Doug might know because he shots animals and sometimes I guess you're unaware of how long they'll stick around.

In those situations, shooting in Rec 709, I usually use the in-camera WFM and expose as "high" as possible while not clipping anything and then check how the picture looks like. If, let's say, because of very high contrast, as in backlight scenes, the main subjects look really dark, I raise exposure until they look acceptable, and I forget about not clipping highlights.

I'd really like to know what you would recommend with HG's.

Edit : I found some info in this thread.
