Upload & Sell: Off
I wasn't judging, asking a simple question. If you are a reasonably good photographer, the process is seeing. Once you know what you are doing, that is everything. Actually pushing the button doesn't yield any surprises, so why push the button at all?
Actually, I am an artist and a writer, not a photographer in the strictest sense, and when I've been in periods of not caring about producing prints or showing photography I have left my camera and just seen photos and not taken them.
Not keeping paintings... well, painting is different than photography.
This almost begs the question, "why even bother shooting the photo?"
If you can previsualize it, why not just appreciate the photo that you could have taken or printed if you had chosen to?
Is it a camera fetish?
I won't speak for Makten, but I can imagine other possibilities. I know plenty of hobbyists who have no interest in retaining/displaying/selling their final product. My best example of this is a choreographer who paints as a hobby. She paints over the canvasses and reuses them as long as she can, then she throws them out and stretches a new canvas over the frame. She's passionate about it, constantly playing with new surfaces, paints, brushes, etc. From what little I've seen, she's very talented, but she rejects the notion of keeping even her best work, much less showing it. She's pretty funny about it, too. Her typical response is, "Oh, sure, I could get a show at a gallery and watch my career explode and become a painter celebrated the world over, but then what do I do for a hobby? Choreograph one-woman shows in my spare bedroom?"
For some people, I think the process is the point, and not just a means to an end. If that process includes expensive gear, and they're not robbing convenience stores or swindling little old ladys to finance it, then why judge?
