The New Digital Bolex 16mm 12bit Raw CDNG's

[reddeercity]

Hey everyone the new New Digital Bolex 16mm Raw Camera is out,
it Record to 12bit CDNG's in 2k , Philip Bloom has one I guess and he
made some cdng's available for download.
I loaded them up in Premiere Pro, and had no issue viewing there. Color was bang on.
They claim there is 12 stop DR. It has a 16mm sized CCD sensor with a global shutter.
I Zipped up a shot of 56--2k frames and if you like you can download them and check them out
from my dropbox link:  the file  is 117.96 MB

Very, Very, Very Interesting your intrest in The New Digital Bolex 16mm. What is it the CCD sensor with global shutter for control of Alising and Moire or the Vintage look? 12 stop DR? If I'm not mistaking I the Magic Lantern team is workin on 12 stop, but I could be wrong. Just wanted to know what your intrest in The New Digital Bolex 16mm was? I've gain a lot of workflow techniques and RAW understanding from you research so thanks anyway.

short sight via Premiere CC7.1. looks generally fine, but has pink highlights. doin some tests next hours - it seems, ml_raw/mlv will look ok as well with 12bitlog, but then we have to investigate further because of the pink highlights..

[edit] its 12bit without any linearization-table. blacklevel 0 whitelevel 4095

@chmee, I hope the cdng metadata from the bolex  will help with the problem in  Premiere Pro CC 

@dariSSight,  will I do like the 16mm look that it has, I can see I lot of uses for that camera.
first I like the fact it has a global shutter, so no more problems in paning & quick camera movements,
Its records 12bit raw to a  SSD , XLR in and out, full size hdmi connector , 2k resolution
It would be great in events, or documentaries, studio camera etc...
the price is very good around $3200, about the same price as 5D3.


Hear a quick look at the spec of the camera, from there website

I could never work out if the digitalbolex was open source or not.

One thing that disappointed me from the start when I saw this project is the max fps at 2K is 32fps
Couldn't this have at least been pushed to 48?

I mean it's good to see that there are somewhat affordable raw cameras coming out, but I do wonder.

Most likely a limitation of the Kodak image sensor.

Hi,

Newbie, be gentle.

I've been looking at a range of DNG files, all of them claim 12 bit, however if i use dng_validate to output the pre-linearisation pass (so i get a 16 bit compressed tif file pre debayer too) then i only see values from 0-2048 which to my mind is 11bit. I'm using files that have clipping in, so i know the sensor is maxed out.

After the linersation pass with the DNG processing this is expanded to 16 bit using the black/whitepoint and a linearisation table if available.

So someone confirm whether dng_validate is correct or not?

Are these files internally really 12 bit, because it doesn't look like it...

thanks
Paul
