Before
After HDR techniques
After HDR techniques. This photo does not have the depth of change that you have seen with the others, this is because the sun is to the left and is already providing a good coverage of light. HOWEVER you can see by the large tree it have significant detail compared to the previous photo.
This photo was taken by "Marjorie J. Clarke" You can reach her at mclarke@hunter.cuny.edu. This was completed after some HDR techniques.
