Here is an HDR photo I did for Photoshop class. We had to take a photo(s) and make sure they were good enough for a client to buy. I think this turned out well, but I will be editing a few things on my 2nd draft.
This was taken at Natural Falls state park in Oklahoma, just off of Highway 412 on your way towards Arkansas.
