No one is blaming the JPEG format for ugly images.


Those are his words not mine. He put user options as part of the jpeg conversion.

You are wrong and misreading what I wrote. "JPEG processing options" does not refer to the JPEG compression algorithm. It is common to refer to all of the camera's picture control options as "JPEG options" because they apply to the JPEG images the cameras create and not to raw data. That's not a reference to the JPEG compression process.

There is nothing in the JPEG compression algorithm that address a clarity adjustment. Clarity in the Fuji cameras I was talking about is one of the camera's picture controls that applies to JPEGs the camera creates -- one of the JPEG focused adjustment options in the camera.

I have never suggested that the JPEG compression algorithm is responsible for the IQ problems I identified. I explained in each instance what was causing the problems I identified and never did I say it had anything to do with the JPEG format or JPEG compression. When I demonstrated poor noise suppression in Nikon cameras I didn't say it was because of the JPEG format. When I showed the loss of fine detail in the Fuji JPEGs I noted it was due to demosaicing -- not JPEG compression. Just read what I posted.

I fyou dont mean those then OK i agree with the other explanation.

I still believe that camera processing speed has nothing to do with getting the best image. They can have all the time they want, because everything is already in the buffer. If one gets a bad photo, the problem lies somewhere else.

You really want to admit that you were dim enough to think that when I explained how my Z7 did a comparatively poor job of noise filtering that I was conflating that with JPEG compression?

"The camera makers compromise the in-camera processing in deference to the need for speed. Fuji recently experimented with this problem and added some JPEG processing options into their cameras with a caveat that they would slow processing -- clarity is one."

Not admitting to something i never did. But your being an idiot not notice im not commenting on the Z7

Same applies; you were really dim enough to think I was conflating a clarity adjustment with JPEG compression?

Your words are bright as day:

You're clearly wrong about that. I gave you an obvious example with the Fuji cameras here: https://www.uglyhedgehog.com/t-787932-38.html#14392494 Fuji adds an option to apply a clarity adjustment in their cameras but takes the option away if the camera is set to burst mode. Why disable the option in burst mode?

How about you show us then. You have a D610. Take a low-light photo with the ISO set to 6400 or above. Use the in-camera noise filtering and post the SOOC JPEG along with the raw file. Do as good job with that in-camera noise filtering as I'll do with your raw file.

Why should I do that? Low light is low light. Only stupid persons or those who have no options will shoot at low light.
That is your main problem, you are pushing the tool beyond its limit and blaming it for not achieving your expectation.

You are limiting your options.
For many years I shot events. Mostly indoors, where adequate lighting was rare. The ability to shoot at high ISO and deal with noise in post expanded my options significantly. I started with a D200, which was noisy above ISO 800, then moved to a D3 which could handle ISO 12K or more with similar results.

No sir. I shoot as I please, and I shoot as want.

I was just telling how it is. Comparing the JPEG SOOC to editing a RAW image in a lopesided test is a stupid argument, and no one in his right mind should even think about it.

I don't understand what the confusion is about.

The discussion is about having the camera render a bitmap from the raw data, or using a parametric editor on your computer to render a bitmap from the raw data.

"User options" are part of that process either way.

That doesn't make any sense. Comparing the JPEG SOOC to editing a raw file (not a "RAW image") is a valuable exercise and it is exactly what the OP was asking, although the question was not sincere and it was initially not phrased honestly.

Oops sorry, kind of assumed you knew how to use your camera. That's OK I can do it for you. The folks at Imaging Resources have thoroughly tested the D610. Here's a link to their ISO 6400 studio test shot in which they set the high ISO noise filtering to Normal: https://www.imaging-resource.com/PRODS/nikon-d610/D610hSLI06400NR2D.NEF.HTM You can donwload both the SOOC JPEG as well as the raw file.

The high ISO noise filtering in the SOOC JPEG is really bad and it just plain sucks by any comparison with modern noise filtering tools. Here's a side by side look at 100% between the SOOC JPEG and the raw file processed in PL-7 with PL-7's prime noise filtering set to default. Look at the yellow fabric in the top of the frame and how badly the SOOC JPEG has lost the fabric's texture and detail and the back wall is still noisy. The noise filtering is eating up the sharpness in the image and not doing too well removing the noise.

And that's your camera demonstrating that you're wrong. The problem with this bad SOOC JEPG does not lie with the user or the user's choice of camera settings. It lies with the crappy algorithm in the camera that the JPEG shooter is forced to use and that's there because the Nikon engineers had no option to use something better because something better would slow the camera too much.
