If you like HDR photography, you've more than likely seen the work of Trey Ratcliff (aka Stuck in Customs). He is more than willing to share his insights and the process behind his photos. If you want to learn how to take HDR photos, you should definitely check out his free HDR tutorial. If you like these, make sure to check out more of them on Flickr.
Some beautiful shots of bridges and cities by New York City based photographer Andrew Mace. He sure has a way of making everything seem beautiful and interesting. Make sure to check out his website to see some cool information about his photos and things he's learned along the way.
Wow. That is the word that comes to mind when I see Mikko Lagerstedt's photos. Mikko is an incredibly talented, self taught, photographer who only started taking photos in December of 2008. I wish I could share every photo he has taken because they are all that good. Each one is well composed, has an amazing atmosphere, and incredible lighting. You could get lost for hours browsing his photostream.
