Funny this thread should happen while I was on vacation. I just returned from a week photographing in touristy areas. However, we were at them during the week in the semi-off-season so it was possible (with patience) to get a lot of shots without people in them. Also, we have been to this area several times so we hit a lot of off the beaten path. With repeat visits, my vision of what I want to shoot has really evolved over the years, a lot closer in and intimate, sometimes more empty and abstract.
As to the postcards and calendars, I don't desire to recreate them, but they do make me want to go someplace and see what I can come up with. It was 15 years ago in one of the most photographed cities in the world, San Francisco, that the film photography bug bit me hard and I made the decision to pursue it as a serious hobby. I was working a consulting gig with nothing to do on the weekends except find the bottom of too many bottles, so I just started exploring with my camera. Then I started wondering why my results were so inconsistent and generally terrible. Yet there were people who really did know how to get consistently good results, as the postcards, calendars, and serious art-types proved.
Since then, the rabbit hole has only gotten deeper, the farther I have gone.
