I love this conversation! I have found that as more time passes my clients ARE buying my more artistic shots. My last two large canvases were done with the tilt/shift.
Whether that is because I'm getting better at finding my target market, my work is improving, or because I have a lot of those samples hanging in my studio ( or all or none!) I'm not sure.
I have also found that what Julie says about outdoor shooting tends to be true- I'm more likely to sell a book or large piece from an outside session.
Great topic!
