I have asked this question on other forums , but I still find it a fascinating question, so I thought I'd ask it here. I take photos as a communication. It allows me to describe things in ways that are just not possible without. My main subject is fungi, where I take still or moving pictures and I have found it very effective as a communications medium. I take lots of other photos as well, but they are all a communication. Sometimes I don't ever get around to processing them as I find that saying things with photos takes an effort and sometimes the effort seems too much. I like taking the photos and seeing that I have got some good ones, but I can't be bothered with the post processing and the showing to people part. So I generally stick to the things that I love the most and that I have channels of communication for. Some people I know love the technology and the photos are just a byproduct. They are mostly used to verify how well, or badly, the equipment is working. Not my idea of a good hobby, but they certainly help me to stay up to date with the technology. Some say they do it because they can't paint. Which of course leads to the question, "why do you want to paint?"
