Being a realist, I have trouble finding subjects that have not been brought to a canvas before. I may have done it once, when I did a portrait of Jordan working on a laptop computer. I have yet to see a painting with a laptop done before I did mine. How many artist out there look for things that haven't been portrayed before? For me, looking for such things has always occupied my mind.
I settle, these days, for what I put together in a painting. My window series is a way for me to mix still-life setups with landscapes. White daisies against a dark stormy sky is one of my latest. I collect photos of skies and other things that one finds in the landscape. Painting the still-life, direct from life, I may add a landscape from a photo or from a plein air painting. Trying new combinations keeps painting interesting.
