I’m sure you’ve heard how soft, northern light (or southern, if you’re on the other side of the equator) in your studio is critical. But it’s all too easily an excuse, another aspect of Never Moving Beyond Liking the Idea of Being Creative. Work around what light you’ve got; your paintings aren’t going to be hung in unchanging light anyway.
This photo shows sunlight blazing through the northwest-facing window near my easel (and sunlight isn’t as rare on Skye as many believe!). Yes, I could moderate it with a blind, but that would not only shut out the view over the sea, but upset studio cat who enjoys lying on the wide windowsill.
