The purpose of the test being to test the ability of each camera’s images to be manipulated after exposure. I have graded each output to try to get it back to neutral using Gamma and density’s chart. As you can see the Alexa responds very well where as the 7d footage fails in highlight exposure detail and it’s codec compromises it’s ability to be pulled up in the darker regions. It’s interesting and telling and goes part way to explaining the more than substantial price difference.
If you want a full res version of this, it helps to see the differences more clearly and you can really see the noise increase then donload the quicktime from the link below, it full 1920 * 1080 be careful to right click and download and not left click and run as its 1.5Gb
