Change Primaries or RAW value?

Hi,
lets assume that you are playing with R3D file.

And camera metadata is 800.

But it seems picture is little dark. You need you brighten the picture.

Which way is right?

1-Go to RED RAW value (in Resolve) and change ISO to 1000,1200 etc (or play with RED RAW parameters, including FLUX, brightness etc)
2-Keep RED value 800 and change Resolve Primaries

It seems solution 1 is more proper since it just "shift" the dynamic range.

am i wrong?

They're each slightly different in the underlying math/algorithms that they're using to get the job done. But they each get the job done and the exact set of images you're tweaking will determine which is better. It's a case by case thing. There isn't a 100% blanket answer. I'm sure an experienced colorist could get the same result by starting with each method.

Your Resolve primaries are being applied on top of the de-bayered image. So if something is being crushed/clipped/tinted because of the raw settings, your not going to be able to recover it with LGG. So in some instances, you will need to use the raw controls first and then LGG on top of that.

Hi Paul
i am totally agree with you. this is what i am thinking.

I typically will conform an R3D sequence in Resolve and then scan thru the timeline to see if everything is within the best RAW exposure and tint range possible before I start coloring. I will adjust ISO, color temp and tint if I see any problem clips (usually saving a preset and using it over multiple clips). Takes a couple of minutes, but it will save you time later.
