All my keepers are printed 30"x40" and ..... just kidding.
A little of this a little of that.....
About 50% spread across several photo hosting sites. The other half printed 8"x10". A couple of fairly large prints, mounted and laminated hanging somewhere. The 8x10s are in books at the shop categorized by location to help sell trips. I hand out slide show CD's to all my students. A couple large prints were hanging in a someone's booth at DEMA. I've licensed a whopping 8 images. Haven't attempted to peddle any more.
I've been urged to do more on a professional level, but I don't have the time or inclination. I've been urged to enter competitions, but I don't like competitions. I'm so critical of my own work, I'd go insane. Mostly I just try to share.
My goal is to collect a dozen underwater shots that I think are great, get them blown up, framed and hung in my personal gallery. So far I have a lot of empty walls. I'm trying to do the same thing on land, although I'm working on other projects like photo essays, again for my own edification and sharing, not personal financial gain.
