Hey everyone!
I'm having some trouble with Glare getting on my color checker.
so here's how my studio is set up.
I have my shadow box 4 feet away from me
I have fabric blocking glare from the light source on my Shadowbox
I set my light up at 35 degree's from my canvas to get no glare on my Canvas.
I have black fabric behind my light as seen in the attached pictures as well as a darkly painted room so I get no glare from behind me.
so my light and studio is set up perfectly where there is no glare on my canvas.
Unfortunately I'm,getting a real nasty glare on my color checker.
Watching Draw Mix Paint's videos he mentions that glare on a color checker comes from what's above and beyond the Color checker.
I've held up cardboard. hung black fabric from the ceiling and I cant seems to get rid of the Glare on the color checker.
As seen in the attached pictures I get rid of the Glare on the color checker by tilting it away from the light towards the wall.
so my question is how can I get rid of the glare on my color checker and still have a perfect studio lighting for my canvas?

Welcome to the Forum.
Great setup and great photography of the problem.
This is not glare. The reflection off the black paint on the colour checker could be described as specular highlights. This is natural and expected from a well lit, glossy but uneven surface.
Suggestions:
* Attend to the side spill from the ceiling light units reflecting off the white ceiling paint. ( Why are these diffusers so unevenly illuminated? Are these LEDs?).
* Use a lower viscosity paint i.e. thinner paint so it levels out.
* The angle of incidence equals the angle of reflection. As you discovered by tilting the checker to the side. Anything you can do to adjust the colour sample arm angle eg bend slightly up or down will help.
* Try colour checking from a position closer to the still life, then from a point further away than usual.

A degree or two change in the sample value arm may be enough.

Have a look at this setup as an example. Three or four bright LEDs shoud be enough.

Don't over-think it.
Good thought, but a light shade will just introduce dissimilar light between the shadow box, colour checker, palette and canvas. The aim is to be able to read, mix, adjust and match hue and value so that the subject is replicated on the canvas.

you can adjust the temperature and brightness via remote control to get it exactly as you like, and reposition them easily as they are on stands. CRI is 95+
I might replace mine as they are bulb with the big cumbersome hood/shade and take up too much of the little space i have.
That is about one third of the recommended detail and fine discrimination light levels.
Below that expected of a decent desk lamp.
Six of these units will do the trick.
