Either increase it, or decrease it in…the cool, warm, midtones, brights, darks.…Any part of the picture you want.…Watch what happens when I adjust the cool.…Keep in mind that that umbrella is kind of a cool color,…as far a color temperature goes.…Now, moving it to the right means…I am pulling out more blue.…I am increasing the amount of spill suppression.…Moving it to the left, I am reducing…the amount of spill suppression, so it turns more blue.…
