OK so I've balanced my whites and started using my new color checker but am confused about something.
When I use the checker to match a color from my still life, it looks fine on the checker but when I actually paint it on the canvas, the color looks too dark. My canvas sits on my easel at 90 degrees while the arm of the color checker is at 45 degrees when I hold it out at arm's length.
What am I missing here? (Note: when I balanced my whites, I used a wedge at 45 degrees.)
