HDR isn't a gimick, you may not like it and that's ok, that's your opinion. It is an artistic method of taking a scene that cannot be shot properly with a single exposure, and combining multiple exposures into one photograph, capturing all available detail.
I like the video, OP. Keep working on it, It's a little off, but I'm sure you can improve it with some more playing around.
what's with all the hate in this thread? people are such assholes to each other when it's relatively anonymous
