DNG files information - Photoshop vs Davinci Resolve
« on: June 27, 2014, 04:50:08 PM »
Hello!

If anyone can help me:

I don't see the same amount of video information in the DNG files in Photoshop vs Davinci Resolve 10.

I have alot more information to work with in Photoshop than in Davinci, and the problem is i want to use Davinci for Color grading.

Here is an example of where i can go with Photoshop and Davinci:


Original Image:

Photoshop (lowest possible exposure without loosing quality):

Davinci (lowest possible exposure without loosing quality):

It might only be a setting in Davinci Resolve, but wich one.

If you have any idea/tips don't hesitate!

Let me know,

Thanks,
Will

Try it in Resolve 11.

Choose CinemaDNG. BMD Film color space and gamma. Check Highlight Recovery. Try auto color, then use the highlight and shadow controls in the Raw panel.

If still struggling try changing the Color Science from Davinci YRGB to Davinci ACES.

Can you upload the DNG so some of us can have a go and see if we can improve on it, then publish the method?

I had a crack at your DNG in Resolve 11.  After a few tweaks I came up with this:




Very similar approach to one taken with ACR.

Here are the project settings:




And here are the Color Tab Camera Raw settings:



I did Auto Color (Alt or Option A) on the first node to take the image out of its initial log appearance due to using the BMD Film color space and gamma.

Quite a bit of flexibility.  I'm sure others could do an even better job.  I'm looking into using LAB color space in a separate node to blur the color channels to remove noise, but not 100% sure about that yet.

This is also a great example of how powerful the Highlight Recovery option is.  Together with the Highlights slider in the Raw controls, and the soft clip adjustment in the Curves section, it is possible to perform some serious rescue to Raw footage if necessary.
