Loving this custom Picture Style for the Canon DSLR's. This is quite a nice improvement in the dynamic range category which out of the box, is pretty much horse s^#*. This custom curve isn't going to buy you 10 stops but it might help make you forget you're shooting video with a stills camera.
This gentleman, Luka Crnkovic-Dodig, was kind enough to create a tutorial on how to install Superflat01 and what it does to your images. This is really fantastic. Thanks, Luka!
Here is the Superflat01 Picture Style. Follow the instructions in the tutorial to upload it to your 7D, 5D Mk II, or 1D Mk IV.
