Yes, this is a big claim.
Allow me to explain how I came to this conclusion, and prove it to you.
First off, the evidence. This is a video containing 5 compositions that were each shot with either 2K, 2K (and processed in post), or 4K.
It should be easy to tell the difference - so see if you can tell!
Not so obvious is it....
In the video I encourage you to download the video and pixel peep, please do.
I have pixel peeped the shots directly on the timel
