Inside Biosphere 2, Arizona is a complete ecosystem meant to keep a group of people alive for months on end. That project ended years ago but the building remains and it’s worth a visit if you’re in the area!
Just in case you didn’t see yesterday’s post, 3 hotel rooms going for free on the 25th of September if you’re going to the photowalk the following day! Just leave a comment if you can definitely go and want to be in with a chance to win.
I thought there might be a rush on this but, boy is it proving hard to give away such a good prize! I’ll just have to claim one of the rooms for myself! 
I would love if you had some photo tech info attached to these, like exposure, ISO, lens, focal length, etc.
I tried adding a plugin that showed that info, from the meta data WordPress grabs (I think) but it seemed to work only sporadically and after some time fiddling about with it I gave up.
One of these days I’ll devote an evening to sprucing up my blogs.
