I've probably checked out half this thread by now and there's a load of really nice pictures (as well as some pretty crappy ones that look like haggis, but let's not dwell on that). Being a bit interested in photography myself I'm really curious as to what camera was used for the photos and if any artificial light was added. I bet the iPhone is by far the most common, but it would be interesting to see how its pictures holds up to those, if any, that are shot with a point and shoot or even an slr.
For the next poster, would you mind indicate what hardware you use? maybe we can get a new custom going...
