Starting Point for Grading in DaVinci Resolve

In a prior post about Resolve, I wrote about my quick fix to get rid of magenta in the shadows and I mentioned it’s only one of several ways to get rid of it. All you want is a good starting point for your grading.

It’s in the grading that lies the power of the uncompressed raw CinemaDNG of course. That’s why you bought or use the camera in the first place.  As Ikonoskop has always mentioned: the dII does the capturing, your computer does the processing afterwards. There’s no processing of the image in camera. No curves, no rolloff, no LUT. There are many things you have to be aware of to get the most out of your Ikonoskop footage. After all, it’s all about luminance and chrominance. And with the dII, it’s you who’s in control, not the camera. You not only need to be maybe the director, DP, editor and colorist, you’re also the guy or girl in the lab developing your film.

That doesn’t make it easy to get quick results at first of course. It needs studying and a lot of trial and error. But after a while you get better at it, you’ll make your own presets and LUT’s you can trust and most of all, you will have control over your images like you’ve never had before.

So if you see footage out there with whites that aren’t really white, with harsh highlights, with a magenta or green or blue or whatever cast in the shadows, and it’s difficult to assume it was an artistic choice, don’t go blaming the camera or the sensor. They’re quite alright actually. It’s all in the hands of the one who’s responsible for the grading.

Just watch this to see how nice Ikonoskop footage can look:

But anyhow, I started out by mentioning those other ways to get a good starting point in Resolve, in addition to my IkonoVinci.lut. Apparently not everyone finds it so easy to install this LUT. And I really suck at making tutorials.

So I’ll leave the making of tutorials to people more capable and this leads me, quite seamlessly, to another way to get a good starting point without magenta in the shadows. It’s written buy a new Ikonoskop owner, Jesse Borkowski, and it’s a great tutorial. I’m not quite sure about using the Linear Gamma setting, but that’s just my opinion. 

The third possibility I’d like to share with you is something you might like if you’re used to working with LOG style footage. Like ARRI’s LOG C or Sony’s S-Log. Set the color space, in the Camera Raw settings (see video above) to BMD Film and be amazed by the details you’ll see in highlights and shadows without any strange color casts, but with the all familiar washed out LOG type ‘look’. Now drop your familiar LUT’s on your footage, and I’m guessing you’ll find that the result will be pretty close to what you’re getting with other LOG footage.

Getting rid of Magenta in DaVinci Resolve

UPDATE: obsolete as of firmware 1.27 (March 2013)

There’s a lot of magenta in the shadows of Ikonoskop footage in DaVinci Resolve. I don’t think it has always been that way, but it definitely is the case in Resolve 9 lite.

There are several ways to get rid of it. I offer you one solution here that’s very quick and easy. In my opinion you have to fix it before you do any Color Correction in the Color Tab. That’s why I’ve created an input LUT that fixes the magenta issue: IkonoVinci. Well it will fix it untill Blackmagic changes something on the decoder side and/or Ikonoskop change something on the encoder side. Then I’d might have to make a new one ;-)

This means you don’t have to fiddle about in the CinemaDNG settings (Camera Raw tab) in Resolve. So leave the White Balance, Color Space, Gamma settings and use the Camera Metadata to do the Decoding. 

Unpack the zip and copy the folder into the LUT directory of DaVince Resolve. On OSX this would be: Library>Application Support>Blackmagic Design>DaVinci Resolve>LUT.

Now go to your Project Settings image. Select Look Up Tables and select under 3D Input Lookup Table the IkonoVinci.ilut.

Then hit image

Now in your MEDIA tab image you’ll still see the magenta. But when you go to the COLOR tab image, you’ll see it’s gone. Now you can start grading.
