You might be a photo geek if you have painted your walls 18% grey.
Or added focus targets
Or see pattern noise when you close your eyes.
If I rub my eyes, REALLY HARD, I see some cool color patterns!
If I don't then the noise is pretty random and organic and confined to luminance channel only.
Since these sensors are always stuck on live-view I don't have the software to boost in real-time to check for possible underlying patterns. It's OK tho, because in normal earthly lighting conditions they have exceptional dynamic range, resolution and the ability to identify the faintest of adjacent shade/tonal differences, probably exceeding 16 bit/color.
And with that I'm gonna go away and let that post-count sit for a little while.
