Which is going to be the better choice when using raw capture?
Setting a custom white balance using an expo disc prior to creating an image or series of images in the same lighting.
Or using the x-rite color checker in my first image and then making the corrections in lightroom?
Would it be redundant to use both?
Any help would be greatly appreciated!
Personally I think many (I've watched them) people use the expo disc incorrectly and while it still works, to use it correctly is more challenging that shooting something like the color checker (or a whi-bal card or even a simple grey card).
To use the expo disk correctly, you have to aim the camera at the light source of the scene, often requiring you to physically move the camera to the subject. This way the light hitting the expo disc is the same light hitting the subject. For some things it doesn't matter much, but it seems much easier to just hold something in front of the camera so the light reflecting off it it is the same as the light hitting the scene.
I suppose the only advantage I can think of in setting the white balance in camera if shooting raw is it might make the previews look a little better? To me it's faster to shoot a whi bal card, then set the white balance and sync that to the images in Lightroom than it is to set up a custom white balance in the camera.
