Indoor sets hold a lot of interest with me, they are just tough to scope out. Usually harder to find interesting indoor places without any people around, and a lot more "you're not allowed to be here". Usually they take quite a bit longer too because of the exposure time needed for low light. They'll always be in mind when I'm taking shots for these sets, if I can find indoor places along my route.
My girlfriend's actually sharing a lot of interest since she's big on photos, most of our dates have been the two of us walking around with cameras lol.
The next destination for HDR ProSets is going to be Yosemite national park
as decided in the poll thread. I'll likely be heading out there early November or possibly sooner (I need me a vacation)!
Also, here is the image I did in the tutorial which I forgot to post. Sorry about that!
