I noticed that the Nikon D5100 has an in camera HDR mode so I wanted to give it a try since I am not that good at HDR.
I know this doesn't relate to DSLR video, but I think HDR is helpful in learning about shadow and highlights so that is why I included this tutorial on HDR.
Since I have Photomatix Pro I also compared it to that as well.
To be honest since I am not that good at HDR yet, I kinda think that the in camera HDR did a better job than I did.
