  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Just foolin' around. Background T32, face in covered, heavily shaded doorway T1.7 (ISO 400).

1st one is not worked much... nothing clipped and nothing crushed pure black. This test is the "hard way"... putting the subject as the darkest object in a high range scene. We are not debating whether or not the details or noise in the shadows of the trees are good enough or not.

2nd one is worked with highlight recovery only to show that the info is really there. Not as a grading option.

Metered with Sekonic Cine.

This is Build 16. Build 15 will do this as well, just won't look quite as good... :-)

This is more about grading technique and not throwing away info.

I can see that there is information there in the second image, but I have to say that it looks terrible. It's not an acceptable image. I'm not trying to jump on you, but it doesn't seem like a very good grade. Is this how the new noise looks?

Maybe I should delete that 2nd one? It is not a useable grade. It is just hyper-extended to show the info is there. Or were you kidding?

Jim
 
The noise looks much better. Far less patterning, I'll need to hold out to see it in motion though.
 
I'm not kidding. I would take the second one off. Do you have a different grade, something in the middle? I think that the second one just makes the camera look noisy.
 
i think you should leave it. I agree that it's "unacceptable" but it shows the literal range. I think there's too much discrepancy between literal dynamic range and the more loose "usable" range.

I don't know much about film, but it seems everyone continuously throws out 13 stops all the time for film, just as a given, its a rule, film has 13 stops, this is apparently common knowledge everyone knows (whether they've ever shot a frame of film or not). But then ppl test RED and go, "eww, well you get detail but its not usable, i mean really, you can use about 7.5 stops..."

I'd like to see both literal and usable DR tests from all the major players to really get an idea of whats what. RED ONE, Vision2, F23, F900, Genesis, 16mm, even DVX100 so I can compare with what I've shot a lot with.

Obviously I'm not capable of providing these test, and who knows if we'll ever see them, but i think put an end to a lot of the confusion.

Just consider that the 2nd one is a good 3 stops open from meter. So that's what a 12 1/2 stop grade looks like.

It's not a cosmetics commercial, it's a look at an extreme contrast situation. Thanks, Jim.

forgive my ignorance: why do you call it 9.5 stops in the title, but then say its a 12.5 stop grade?
 
I know it's not a cosmetics commercial First light. I'm just saying that it might not go over so well with the Red skeptics. I'm leaving it at that.
 
so what does 9.5 stops refer too?
 
T32 -1.7
To pull out anything like that is to my calculations 9 stops under exposed and hold that much detail while the background stays almost the same. Damn. I have been to hundreds of telecine sessions and that would be a good grade in anyones book. Obviously this is showing a more docu situation but if you have some fill you are golden. This blows my socks off. I have seen Jim grade images before and I don't think most people understand what he knows... Curves. To anyone who thinks that the second image should be deleted I wonder how many times you forgot your light meter and needed to have a colorists save your .... project. If this was a docu and not a larger project with more money for fill etc. I would be really pleased.
 
same here. Very impressive given those extreme circumstances. Film is going to have a hard time there as well (not that I'm comparing) How many people would choose to shoot in those circumstances even if they were doing a doco? Not many when you could just move subject and camera around 30 degrees.
