Red Updates

This embeds only what is captured by the exposure (10-12stops latitude) into a RAW frame? (The levels of which get adjusted in post) Not boost detector gain then encode?

So basically we don't push ISO/detector sensivity at all we're just doing basic image manipulation.

roughly yes, as I understand it. Someone said, think of this system more in tune with a still camera and it's ability to shoot Raw files. If you shoot raw for stills, you do all the manipulation in the post with Adobe or whatever. I'm very much an amateur on Digital Stills but the general agreement with a semi-professional camera like the Nikon D200 seems to be you shoot as flat as possible and then manipulate later because with Raw you've got so much more latitude. Certainly that extends to contrast, saturation etc. I would think the Red post with Raw might even have noise reduction abilities in the same fashion as working with Stills apps? Of course, all these processes come with compromises in image quality, not matter what format you shoot.

With RED we have a fixed sensitivity detector yes/no?


JohnF

Every camera has a fixed sensitivity detector. You add gain to the output of the detector by amplifying the signal. Red simply takes the output of the detector (RAW) and adds the gain in software instead of in the camera.

Let's say we're really trying to pull some picture info from dark picture/blacks and we "push" the ISO. How much picture info survives being compressed by REDCODE? (Maybe this is a question for Gabby's test on #8!)

I'm just trying to figure out the signal path!

JohnF

Yes Gibby - please make this part of the tests...comparing the in camera gain controls to post work on the Raw files!

Of this I am aware. What is interesting me is the issue that when using REDCODE RAW we are adding gain post compression.

Hopefully this won't be a problem - only testing will show.

So many questions to ask and tests I want to run on this camera...

REDCODE RAW v's RGB

REDCODE RAW v's RGB

If you record REDCODE RGB then any Gain selected is applied prior to compression i.e its already affecting the RGB image the camera records. If you record REDCODE RAW, then Gain is just stored as metadata, and it is then used (or not, as its your choice) in the conversion of 12 bit RAW to 10 bit or 8 bit RGB / 4:2:2 in post production.
