AF100 Latitude

[jgardner]

I searched and couldn't find this. Any one shoot charts and figure out a general range of latitude?

During "A Verse Before Dying" we measured about 10.5 stops.

would be awesome to get something like what Technicolor is doing with Cinestyle for the 5D in our beloved AF100's.

The Single Chip Camera Evaluation pegged it at 10.2, using a different chart than we used. So somewhere in the range of 10+ stops.

What exactly is that?

Something in regards to compressing the entire range of the sensor before it records the image. I'm not too entirely clear on what it does however. Seems to be some control of the curve pre recording.

It is a picture style, much like Standard or Vivid, that you can load onto the camera. Supposedly shooting with it is the closest you can get to getting a Log-based signal from the camera. Here is a video from NAB on it:

EDIT: actually you are supposed to get a TRUE log signal, which is ridiculously awesome.

Seems to me like something similar might be achievable on the AF100?

I would guess so. That would be pretty cool!!

Log isn't very fun on the acquisition side of production .. and unnecessary (IMHO) if you're
not mixing and matching media / cameras.

If they did provide log, i would hope they would allow monitoring with it off ..

The closest you can get to LOG on the AF is shooting in Cine D and low chroma. But I would like the ability to do a custom curve on the AF.

Recording log in 8bits @ that kind of compression is asking for trouble.

Log would be great on the af100, but again, 8bits. Shoot cineD as suggested.

what if an avcintra version comes out.. would that work?

Can't disagree with you there, however the 5D that they were using, was that not being recorded as 8 bit?

based on what ive watched from interviews, the technicolor doesnt really increase anything... it just makes it easier to grade

I'm guessing it's something like the superflat picture profile with adjustments in the Red Green and Blue curves as well as a fancy name??

thats how im seeing it too

It applies a logarithmic curve to the luminance value resulting in a super-lo contrast
image. Sort of like dynamic-range-stretch on steroids. It makes the luminance
values uniform throughout the range.

This allows the post guys to have a uniform luminance space where they can shape
the contrast identically (or nearly so) without worrying about where the media
came from.

Easy on them .. PITA for everybody else
