Color Grading Two Cameras To Match


Recommended Posts

Hey!

I am currently editing and coloring a Christmas commercial for an e commerce business. During our shoot we used a Sony a7rii, and a Canon 5D Mark ii. Im currently trying to match the footage the best I can so I can begin to color properly. I used the sony's slog profile on the a7rii, and a neutral profile on the 5Dii. I have attached some stills of the two different cameras and their look straight out of camera. If anyone has suggestions, resources, or would like the files to mess with to try and help that'd be awesome! I should also mention I am editing everything in adobe premiere.

Canon on top, Sony on bottom

Thanks!

It looks like the two shots are matching up good now. Use the gallery wipe and scope to compare hue and luminance level. I don't think you need to complicate your node tree that much. You could do this corrections in less nodes, using the hue vs sat/hue to control the reds is an example. No need for a parallel node here.

I don't think that's the OP but I agree. All the neutral picture style really is, is a tone curve + hue/sat.

I used an slog to srgb lut, followed by an s-curve, followed by hue/sat layer in my PSD. Those should be easy to copy in any other application.

You can make matching with 3D Lut Creator https://3dlutcreator.com/ . Details in this video tutorial 

 

Unfortunately that assumes one has colorchecker references available, unless they generated the matching LUT beforehand. I believe ACES goal with camera IDTs is to solve that standardization issue.  

OP could try a couple OCIO transforms.

For instance a transform like this > followed by a balancing a adjustment > followed by a cineon to srgb/rec709 transform
