Hi Benjamin,
thank you!
Would be interesting, to do another one with RC to 700 as well, from the original of course.
Because to be honest right now I like the RC one better - the detail seems to be crisper.
And ZB doesn’t seem to have so much fewer on the cushions either.
I wonder if the differnece is the structured vs chaotic distribution.
If you look for example at the edge of the seat, the difference between flat and carved (tiny nobs) areas is really pronounced, whereas ZB has more or less the same density…
Nevertheless, they are both really good - how many images if I may ask?
And honestly, if you need to downscale them even further to 1/10, I really don’t think we need to talk about normal or high anymore, but rather preview or normal… :lol:
Because in the end the main difference between the three is the resolution: 1:1 in high 1:2 in normal and 1:4 (I believe) in preview. So as long as there aren’t any other corners that are being cut, that is it. And if, like in your case, you start with an incredible resulution, you can very well deal with a little bit less… 
Could you add a preview shot to the selection?
