I’m going through Mark’s on-line class step-by-step but can’t get past shooting a still-life photo I’m happy with. I’ve chosen to paint from a photo due to work schedule and wanting to paint perishables. I’ve set up MANY still lives and every time I think I am happy with one, I follow Mark’s instructions on processing the image and print it out actual size, tile it together, sit down to draw it and STOP. I always find something in the image I don’t like…something is not in focus, a shadow running across an object that obscures what is unique about it, or the composition could be better. I know I will be spending a lot of time mixing paint and painting this first piece and I don’t want to start on something I won’t like in the end. How do you all get past critiquing your still-life photo and getting on with it? What am I doing wrong?
