Your bemusement about people not being interested in the format choice leads me to think that you expect the viewer to see it and comment on it? Why? Validation. Why do you want validation about your materials? Because they cost. Are you uncomfortable with the cost? Yes. Is that the viewer's problem? No. What is the viewer's problem? Lack of visual stimulation and enlightenment about the world, which you're not interested in showing them in front of the lens.
not at all. it was actually a burtynsky that elicited the non reaction! anything beyond the resolution of an ipad gets automatically downsampled in peoples' brains it seems.
