This is directed at nobody in particular...why go to the trouble of taking a technically ideal image if it lacks the artistic value to hang in your living room?
I think there's many reasons, to name a few:
- learning or practicing certain techniques
- creating memories of what you've seen
- documenting subjects for others to see
- to demonstrate certain techniques for others
- for fun
Creating images for artistic value is only one of the reasons people make (technically ideal) photographs and I think artistic value usually overrated as well as based on personal taste.
