Thanks, Opsec. No, never considered turning pro, but I have taken some of my better pix and had them printed, then framed them myself, to sell at fundraising auctions associated with kids' school.
And I have considered selling them, complete with a watermark(!), as downloads to someone willing to print and frame their own, for cheap/quick apartment art. I could send you some for that purpose for free, if you like.
I shoot my pictures on higher-end "prosumer" point-and-shoot types. Easier for me than trying to lug around a bunch of lenses and filters. But I keep wishing I had a polarizing lens for dealing with glare on sunny days. I used to make sure my point and shoots had filter threads, but almost none of them do anymore, being considered superfluous (OK, so where is my auto polarization feature?).
"Digital darkrooms" make some optical accessories somewhat superfluous by giving more total control over the picture. For example, suppose you were taking pix of 16-year-old sweathearts, and you wanted to soften the girl's complexion, which is flattering to young women. Using a soft-focus lens would soften both their faces, making both of them including the boy look softer and more feminine. What I would do is select just the skin of the girl's face, avoiding edges that define her face, do a slight gaussian blur, and fade it onto the original.
One thing I would like, is a tiny pocket-sized camera to bring with me all the time, so that whenever a "Kodak Moment" hits, I would always be able to capture it if I chose. While lacking in as many features as the bigger cameras, they can still take some remarkable pictures if you know how.
