Easy accurate colour with Chronos 2.1 and Davinci resolve
« on: July 25, 2024, 10:43:08 PM »
After 4 years of fighting to get really great color out of my Chronos 2.1 I just found a youtube video that fixed all my problems.  I've been doing it wrong.
I'm a stills photographer, so this is not my area of expertise, but a few times a year my clients ask for something that needs the Chronos.

I use Davinci Resolve, and shoot DNG raw files.  I'm sure many experienced video color graders worked this out when the Chronos first came out, but I didn't....
I have been opening the Raw files incorrectly, and Resolve's automatic settings will not fix it.

This is the video that explains how to open the raw DNG files , by Sergio Russo https://www.youtube.com/watch?v=XkRvU2FpAI0

The settings that worked for me are
decode color space: Blackmagic Design
input color space: Blackmagic Design Film Gen 1
Gamma Blackmagic Design Film

You must set up the project settings as he describes and the node structure allows for easy adjustment of the image.  But what is amazing is how great the colors are with little or no adjustments.
Thanks Sergio!

Yes, I've been using the same method as well and it works great! Could you post some of your DNG samples? Would like to see how the 2.1 compares to the 1.4.

Here's a few DNG files of a color chart for the 2.1  Xrite Classic Legacy.
Exposure was just starting to show zebras on the white patch.

Thanks! I was thinking more of real-world footage shot in DNG. Only if you can though.

This is what I'm working on today,  unfortunately only one colour featured and the client wants a white background which makes it kind of monotone.
I've also put a graded sequence in the link to show how I used it.  Hope it helps?
