Taste. It takes time and experience to develop, and the masses on average don't have it. As in, they might have developed taste for a few products, but not most products. Hence, the mass-market products are aimed at people with no taste, because that captures the largest slice of the consumers. Random examples: - In A/B tests, the typical personal will rate louder music as better. Hence, all bars and pubs turn their…

Or they just have different tastes then you do, which is a far cry from having 'no taste'. People consistently prefer and rate headphones with more bass as more appealing, for example. That's why consumer brands are bass-heavy. It matches the taste of the market. If you need a flat audio profile where the mids and highs and bass are all at the same level you have to pick up a pair of studio monitors.

Which is what many of us do.

I wonder if this has any implications over iPhone (or cellphones in general) photos in court. This might be brought up to overturn any photo evidence from phones.

...um: https://appleinsider.com/articles/21/11/11/defense-in-kyle-r...

Regardless of the validity of the objection in this specific case, yes it's already happening.

Those of us who have been shooting large digital cameras for the past decade and are some times sad that our photos often come out unsharp in poor light compared to smartphones can at least take some joy in this “no free lunch” demonstration. If this is due to stabilization and not some background blur face detection then it’s probably not something you can (or would want to) disable. Taking a telephoto shot with a t…

Apple possibly caught a break here.

It could have been worse and people would probably have accused Apple of being bigoted or something else.

I hate how much phones lately alters the images. Of course it most of the time makes the images look better, and cameras are a big selling point on a phone. But I don't like how my photos of people suddenly have a filter applied to the faces, how a picture of leaves during fall have vibrance exaggerated, how the sky looks clearer than it really did.

You should be allowed to photograph what reality looks like if you want to.

If anyone remembers the infamous "pickles" drama in the Rittenhouse case, this is another example of why it's so important to know exactly what technology is doing to a photograph.

An aside, the judge's demonstrated understanding of pixels, despite being slimed by most media, was actually quite good. During the trial he demonstrated understanding of how an algorithm can take as input the original pixels and calculate estimated (or interpolated, whatever you want to call it generically) pixels from that input.

No free lunch, but an incredibly good value lunch. The quality that comes out of phone cameras is remarkable. And the times it messes up are so rare that it becomes a talking point worthy of hundreds of comments.

Indeed. I wish I had a list of everyone parroting the wisdom that "it's all about the size of the lens, a smartphone can never be as good as a DSLR" so as to ignore their future opinions. Camera phones now beat cameras worth thousands of dollars with better software and larger R&D budgets, at least in low light performance and color gamut.

Closely related: "It's impossible to just 'enhance' an image to make a license plate readable. Lost information ist lost". This was big due to some US TV show at the time, I guess. Here, the error was in the assumption that the information was lost: as it turns out, there's a wide space of possibilities for image quality to be too low for us to easily read some letters, but good enough to contain the clues allowing a smart algorithm to reconstruct them.

There is a big difference between color correction or exposure compensation and adding non existing objects by ML algorithm.

Modern phones take long exposures and try to make sense of it by analyzing it.

Basically, a one second really dark video can be summed up into one very blurry but bright enough photo. But if you carefully move each frame to compensate for camera movement when summing it up - you might also get a sharp picture. But then the subject moves, or a leaf moves, and the algorithm has to decide which parts of the photo should be a priority for not being blurry. And that would be faces, usually. So the camera now needs to decide what is a face and what isn’t. Just to take one single telephoto picture.

Only doing “in camera processing” like a 2015 digital camera with some sharpening, color curves etc doesn’t cut it anymore. If your phone does that, it’ll be laughed at. Phones these days need to do clever long exposure stacking with image recognition and all.

On Android you can enable a "raw" mode that will capture a dng file with much less processing. You can then adjust that raw file and render it to a jpeg according to your taste. The dng will still have things like stabilization and multi-frame merging, but without those the image will almost always look horrible as others have explained.

How can we enable raw mode? I'll looked into the settings of Camera but I found only a way to disable the scent optimizer.

The Samsung photo app offers to store RAW files (when shooting in Pro mode) as a setting. YMMV on others.

I’ve never owned Bose nor Beats specifically but more generally I find bassiness is a desirable feature rather than a gimmick for dumb consumers. With room sized speakers it’s not a problem because you’ll have multiple cones dedicated to the low end and usually some subs too. Thus it’s easy to have a rich low end without sacrificing the fidelity of the higher end. But with headphones that’s much harder to pull off. S…

> I find bassiness is a desirable feature rather than a gimmick for dumb consumers It's perfectly reasonable to find bass a desirable quality. Depending on my mood I'll listen to music with lots of bass, or with little bass. However, I've zero desire to intentionally alter the frequency response so I'm hearing something different than the musicians and mixing engineer intended. Instead I'll just listen to appropriate…

> However, I've zero desire to intentionally alter the frequency response so I'm hearing something different than the musicians and mixing engineer intended.

I’ve done a lot of research on this as a recording artist myself and what you’re saying here is a misunderstood meme.

Eg Half the records released before 80s have been remastered to sound different to what the musicians originally recorded.

Plus any medium adds colour, vinyl adds warmth to the playback, digital formats (unless you’re using lossless, which most people don’t) add artifecting, etc. Songs are often written for their preferred medium.

So there isn’t really an exact “as intended” but rather a broader “Goldilocks zone” (for want a better term). This is especially true if you listen to a broad variety of genres.

You’ll also find that most songs record in the last 20 years will be compressed to hell and back so they sound good regardless of how shitty the sound systems are in peoples homes and cars. This isn’t an artistic decision, it’s what producers and sound engineers do to make records sound good for the lowest common denominator. It’s also part of the reason why live music sound better (if the gig or club has a half decent sound engineer anyway).

> Intentionally having a non-flat frequency response is equivalent to adjusting the colour space / colour grading of your monitor to not accurately represent colours.

Some content is actually deficient in some spectrums due to the limitations of the media or technologies of the era. Those limitations were intended to be compensated by speakers that added that colour. There’s a reason why studio monitors with zero frequency curve are less common to for rock fans than acoustic speakers (for example).

Lastly it’s also worth noting that not everyone’s ears hear spectrums equally. Our ears don’t have a zero frequency curve and that curve will differ from person to person. Which is why some of the best headphones out there are ones that profile your hearing and then perform post processing on the music based on your hearing profile.
