I have been thinking about my absolutist and dim statements about the worth of one's photography, and I think yours is a saner philosophy of artistic practice.
I recently finished The Stranger by Camus, and it has a way of rejuvenating any latent apathy that may lurk in one's soul. Such has been the case with me.
I think after a handful of cynical threads begun by a certain
Airplane! character, your comments were taken as hostile, but I totally get what you're saying. In the end, its a hobby for 99% of us and worth keeping that in perspective.
One professor I had early in grad school very much stressed the importance of using the best archival materials and methods, and keeping every shot and detailed notes on them. When he passed away, I was invited to help in cleaning out and organizing his office and the darkroom before it got sent to the library archives.
Good god. It was a mess. The man had countless images of Seattle being built over 40 years that were a fantastic record of history, but untold thousands more of test shots, poor exposures, random strangers, and other miscellanea, not to mention entire boxes of undeveloped rolls and sheets. I ended up declining for a number of reasons, and it's all sitting in storage now; someone told me it likely never will be fully catalogued. It would take someone years full-time to get through it all.
I've spent enough time in research archives to know that sometimes various ephemera is valuable—in researching an obscure home designed by a lesser-known local architect, finding original napkin sketches illuminated both the building and architect's history—but a lot of it is useless. (The same file was almost entirely filled with appliance cut sheets) I'm sure there are plenty of unprinted shots in his archive that will be fascinating to see, but only after sorting through the crap.
More importantly, most of us are not going to be lucky enough to have our entire work catalogued and archived, let alone sought out. And so what if some shots are lost to history before they ever make it that far?
Getting back to your original statement: Camus had a profound effect on me in, cheesy enough, a freshman philosophy class. Often when I'm out shooting for my own purposes I get that sinking feeling of 'why am I even doing this? Why does it all matter?' but that could be applied to virtually anything. There's a lot of self-seriousness in this (and many other hobbies) and I try not to fall into that.
