There are companies which release products that enable your camera to capture raw uncompressed data at a 4:4:4 color space, as well as increase of dynamic range ( Reel Stream Andromeda ) but they cost a hefty penny. Now there are 2 and 4K cameras coming to the market ( Red One ) which have a great dynamic range, and resolution equivalent to 35mm film, but the range is not quite there yet. Give it a few more years, and we'll be there.
