Have we reached ‘peak’ image quality?

Perusing some very sharp images from my D810/D850 I cant imagine that anyone would want/need better iq nor could ‘better’ be easily perceived/resolved by the human eye.

Whilst af fine tuning my D850 today with a 70-200 I had to go to 300% to see the difference it was making.

Whilst a computer maybe able to split hairs amongst the best lenses the human eye simply isn’t that good.

So have we reached ‘peak’ image quality?

That really depends on the final use of the image... there is nothing saying that an image may not be viewed at 600% or even more.

And "percent view" doesn't really mean anything in itself... i.e. is your monitor resolution set to 72ppi, 160ppi, or something else?
And what is 100% when printed? If for some dumb reason we say it is 300ppi; that means a 100% print would only be ~ 27" long edge for a D850 image. But what if I want to make a fine art gallery print at 60"?

You seem to be equating image quality with resolution. Most of image quality has nothing to do with the camera. Lighting is entirely independent of the camera as is composition. So is colour rendition. Tonal range is partially related to the camera but also to the skill of the photographer.

To suggest we are at a "Peak" suggests that it's going downhill from here...

Very unlikely, but just like breaking records, future improvements are going to get progressively smaller.

I’m more thinking pure raw technical iq, rather than composition or other qualities a person can bring in photographic terms.

Maybe I got carried away with the term peak! Perhaps I should have said as good as it gets!

I understand where you’re coming from, but you can’t consider image quality in isolation. It needs to be considered alongside the many other pieces of the jigsaw which make up how we see the image - printer quality, paper quality, viewing distance, screen resolution, processing algorithms, viewing distance, eyesight, especially aided. I doubt we will ever reach peak perceived image quality.

I don’t know.... when I shot with film I was never bowled over when stood by the enlarger!!
There can be a huge difference between what a good pre press tech can pull out of a large format trannie using a drum scammer and what someone can get out of an enlarger.

When I had my Canon 5D I thought I'd never want or need a better camera.

I'm sure I read somewhere that someone at Sony said they were aiming to equal the human eye, so there's a target but I'd have thought that the processing that goes on behind the eye is perhaps more important and a more difficult task to better, but maybe one day. I suppose one day blown highlights will be a thing of the past too, so there's that to look forward to.

Other than image quality other stuff would be lovely to have, a global shutter will possibly come pretty soon too and who knows what else will come along.

I do suspect we haven't seen the peak yet.

That a low for ambitions. The human eye is very poor in resolving power but the processing software behind does a hell of a job making up for it.

You might be able to find something on that if you google. Maybe they were talking DR.

I did think it a bit odd but I assume people saying these things know more than I do. With my relatively old now Sony A7 I can often after processing see things that I couldn't see by eye because I was being blinded by the sun and that's a good thing but I'm quietly confident we're not at a point yet at which things can't get any better.

I’m sure we’re not. Even if the improvements are small there are new cameras every year that get better. Im not it’ll happen but we might get to a point when medium format sensors are pretty normal.
ive wondered what to stop someone from making a large format sensor. Might well be overkill but I imagine landscape photographers would love it. Some are prepared to lug around 8x10 cameras after all

I'm sure I read somewhere that it may be possible to empty a well and fill it again and count how many times it's been done. That could be one way of doing it. Maybe. There may be other ways too such as some new sensor tech. I'm pretty sure it'll happen.

Camera manufactures will always say the newest model is the best yet, they have to, so they can sell them. Usually it is only a few tweeks here and there that are different.

That's because they have to be, there are incremental updates but there are also leaps, especially in the case of milc.

Most cameras are probably already better than the human eye, you can often see far more detail in a frame later than we can see just looking - and that's the whole scene not one little area we might focus on and do reasonably well.

There are tweaks yes but I’d say those numbers are within the realms of testing error and you’ve gone to an extreme iso to show a difference.
No chance are those numbers within realms of testing error, the A7iii is a much better performer, like I said, I have used both extensively. An extreme ISO? Plenty of people shoot at ISOs that high.

Heres another sample if you think thats an extreme difference, 1 stop cleaner.

Well your quoting me one website and I’m quoting you another. The dxo testing is well within margin of error. I don’t trust dpreview. Ymmv.
Im using multiple sources to prove the same thing. Everybody in the Sony thread will confirm the A7iii IQ is way better than the original A7 (if theyve used both). So you dont trust a huge difference in measured differences from DXO or dpreview or what anybody says, have you used these cameras alongside?

Still a long way to go yet . And while modern stuff is good it’s not perfect .a perfect design of camera would/ should incorporate a automatic exposure compensation control so you never have to worry about highlights and shadows again ,plus a built in grenade launcher to clear unwanted people from your composition

The grenade launcher is a good idea (particularly for that large chap who always sees me about to take a shot so stands right in front of me to get it very slowly himself) but I really do not want my camera making many decisions for me - highlight and shadow control is too important artistically to not do it myself.
