8k… is it worth it?

If 4k is just becoming mainstream, why is 8k important?  Because it’s not about sharpness. Timur Civan has the following to say:

There has been a lot of argument last couple days about the 8K monstro, what that means, Vs 4K, Vs 6K, vs Helium, Vs Alexa Vs Sony Vs Panasonic.

I think many people haven’t had a chance to try 8K, and see what that actually does to your image.

Here is what 8K means. It’s not about a sharper picture. Actually, its about a softer more organic picture. Think of it like this. The Apple Retina displays whether on Iphone, Ipad, Imac, Macbook etc… Displays more resolution than your eye can see. There by making the image seem softer and more organic and frankly easier to look at. The edges of text, hard lines, and high contrast edges are rendered sub visual acuity. Thereby making it appear more natural and lifelike.

The 8K Helium and 8K monstro is the same idea, but in the photographic sense. When i started shooting 8K, what blew me away wasn’t the sharpness…. it was the softness. IT stopped looking sharp and harsh, and looked gentle. You can see and FEEL the lenses in the image. All their flaws, as well as their strengths rendered accurately. Minute CA, which in the past, would fall on 1-4 pixels of a 1080-4K sensor, and the processor will have to calculate this unexpected color which will taint all those pixels in that region. On 8K it falls on 20 or so pixels. The gradations of the C/A and chroma flaws becomes rendered so they become less pronounced and saturated. The most fun i’ve had is shooting older vintage lenses on 8K and letting the sensor soak up all the character. Small subtle blooms, smeared edges, smeared highlights, etc are not just flaws, but now a fully rendered part of the image. Like I said before… you now FEEL the lenses….. lenses become more important than anything.

Again, if your pixels are so small they can’t be “seen” you can’t see their noise either. The sample of Monstro Jarred Land posted yesterday, you had to push in 400% before the noise even on the Dragon Chip was bad enough to be objectionable. The magic of downscaling, cleans up an image significantly. Even for a 1080P output, shooting 8K means your get 2 extra stops of noise protection. With the 6400ISO noise performance of the Monstro, i can see for a 1080 Finish to commercial or broadcast, shooting 25,600 safely…. if you need it, that is. If not, shoot 800 and have a perfect image.

8K means being able to do your basic post corrections in a bigger space. Whether thats Color, post zooms, crops, VFX or stabilization, getting all the image degrading work done in the “big space” of 8K means, your 4K output will still be super sampled. With even more freedom in the 1080 output space.

See this example: this is 3200 ISO 8KHD then downscaled to 1080 on S35 Helium. Definitely useable. And this is just pointing out a hotel window in LA with no supplemental lighting.

The point is this, the resolution at this point isn’t about resolution anymore. The effective pixels are so small, and so good, that they act more like paint… and less like digital dots.
