Very nice Bill! To clarify for the peanut gallery, what does the x-axis refer to?

If it looks like a duck and quacks like a duck ...

Thanks for that John, interesting that they do it in one direction only vs Sony's OCL 2x2 arrangement. I am also curious about the potential effect of light/e- crosstalk between the two ...

Right. Could your printer print better in one direction than the other? DPAF pixels are quite sparse, 5940 out of 45MP, unless they are all concentrated near the one edge I think they would be lost ...

Hi Frans, what's an LVT target?

Hello Bigger, Valid question, given those MTF shapes. I am eyeballing first null for the R5 at about 162 lp/mm. If the R5 has 4.39um pixel pitch that would be 162/1000*4.39 ≈ 0.71 c/p, right around ...

We are in agreement, Ken. I welcome hardware measurements by dedicated sites precisely because they inform us of the compromises manufacturers are making when designing a particular piece of ...
-
Yes John, my point is that all these functions (linear conversion, compression, adaptation to output medium and viewing environment, making an image more pleasing) should be treated separately. ...
-
Yes Jason, but that tends to mix the quantitative world of photons in and out with human perception, and my current feeling is that the two should be kept separate at least until an output medium ...

Yes, as mentioned elsewhere my HDR10 display with maximum brightness of around 250 cd/m^2 shows less than a stop in the yellow HDR histogram range. I assumed the monitor profile instructed the ...

Those were the compromises necessary to hit a certain size, weight and price point. One gets what one pays for, one hopes. Or do they? And what were the compromises? Head to a relevant testing ...

Hi Mario, I am putting forward the photographer's perspective, as opposed to video/game. It seems to me that in your link they suggest, as I do, that the system transfer function should be linear ...
-
From a photographer's perspective, I would prefer the system OOTF to be assumed to be linear - then leave it up to me to introduce emphasis here or there if I so wished. Those however would be ...
-
Yes, this was a strategy originally implemented by Micro Four Thirds manufacturers in order to make cheaper, lighter, smaller lenses. It makes sense for lens sites and enthusiasts to measure how ...
-
The BBC paper did interesting psychovisual testing suggesting that - for their HDR display setups - system gamma (OOTF) should be used to compensate for viewing environment brightness. I tend to ...
-
I would agree that with the current state of technology curves are all about compression, whether SDR or HDR. Depending on the application this can result in lower bandwidth, power and memory ...

I also thought perspective was a product of the Renaissance - until one day I visited Pompeii in Italy, and there they were, 2000+ year old Roman murals that employed different forms of the ...

Makes sense Jules. Effective Quantum Efficiency with a Bayer CFA has tended to be around 20-25% in the working range recently. I don't know what the Spectral Sensitivity curve of the Monochrome ...
