Recently I did some research on HDR and thought I should give it a try. I used Qtpfsgui freeware. Its an easy application to use but seems a little weak on the processing and I am not very happy with the results.
Before HDR processing
I used a Raw file saving the same image with different exposure stop settings using Raw Therapee. The first at 0 which is the before picture the second at -2 and the third at +2.
