How to use color control patches?
I have a photo of a painting that was taken with Kodak color checker patches on one corner. It looks like I need to adjust the colors in Photoshop. I want to use the color checker as a reference to correct the overall image color and contrast. However, I don't know how to use it as I have never worked with color checker patches before. Can any one guide me how to color correct the image on photoshop?
I am attaching a cropped sample image. The original image is in RGB. The colors on the Kodak patch as follows: Blue, Cyan, Gree, Yellow, Red, Magenta, White, 3/Color, Black.
