I think what Maier left behind for what ever reason is a great gift for everyone, like finding a time capsule or unearthing a historical artifact. Everyone can make up their own mind what a artist is and whether she was one or not. But what I will say what makes the difference between successful artist and a less sucessful artist is who works the hardest. I would say she stayed pretty active with her photography. Now for what ever reason she didn't print most of her negatives, but she still kept shooting film, so we know she was always thinking about her work. I know from my own experience sometimes it is just fun to walk around a find compositions and enjoy what I found even though know one else will ever know what I saw and kept to myself. Maybe that is what Maier did, she just enjoyed the visualization of her compositions and she was happy with that and did not need to have prints made.
