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…

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.

It's important to note that recent iPhones contain the same M1 chip as last year's MacBooks. They are not limited by processing power. DSLR and mirrorless cameras have better optical properties. But they are held back by starting too late and being much worse when it comes to software. These cameras also are limited by their CPUs, which are a decade behind, and by their batteries, which are much smaller but expected…

> It's important to note that recent iPhones contain the same M1 chip as last year's MacBooks. They are not limited by processing power. Correct me if I'm wrong but there's still a huge issue with silicon processing capabilities/power when it comes to image sensors (which is why camera sensors buffer images between shots). I unfortunately don't remember the context but it said something that it was (very far) from po…

iphones come with a15 not m1

Simply adjusting light levels and sharpness wouldn't produce this good/clear of a photo in the conditions presented - AI/ML image post-processing is a hard requirement for sensors like these.

But it’s also just weird. That’s not my daughter’s skin in the photo, it’s 1000 other people’s skin blended together and textured in.

No imaging system reproduces reality. You're always getting a compromised result.

Yeah, even your eyes don't reproduce reality perfectly but at that point it's just semantics. He means he wants to see his daughter the same way through the camera that he sees her through his eyes, in real life, otherwise known to him as "reality". I don't think it's unreasonable to allow context of the statement to allow us to disregard "reality" as it pertains to quantum wave functions, in favor of something more…

As far as I understand the goal of using ML augmentation in camera phones is to capture what the eye sees. It's to compensate for the limitations of the hardware which on its own is not able to produce a true-to-eye result. You seem to be implying that the goal is to improve the photo to be better than reality but I don't think that's the case.

Assuming you don't have a sampling error here, of course.

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.

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.

RAW is not quite what they want (I think). It's HDR+ that they need to disable. The latter takes multiple frames at different exposures and smartly merged them into a single photo, then applies extra color corrections on top. Taking RAW skips the last step, but you still get a merging of multiple frames. Disabling HDR+ will, I believe, take a single frame. Of course on a small phone sensor, the quality will be quite bad.

That‘s hilarious. The way AI is developing we are turned into children full of magical thinking like „I made a great moonshot with my amazing device!“ when it‘s actually 99% AI handholding.

And I’m going to take thousands of pictures and never look at them.

Don’t worry I can now sync them to music and have other humanoids look at them instead while bored out of their minds.

I’ve got nearly the same CPU in my iPad, MacBook and iPhone. I can do the processing on any device…

You don't have the same heatsink on all three, and not necessarily the same number of cores.

This.

My Corsair H150i Pro AIO water cooler and decent airflow case (Define 7 W/Corsair ML140s) allows me to run my Ryzen 3900XT at 4.4ghz constantly, all cores, for any kind of real life workload.

Good luck trying that with a laptop.

I sometimes hang out on mountainbike forums. A user posts that despite a new chain and setting up their rear derailleur according to instructions gear-changes are clunky or the chain skips when applying power on the pedals. The usual reply from the forum members is then to send a photo of the cassette since excessive wear there leads to these problems. This used to clearly show that the user needed to replace their w…

They need to offer an option for a "raw" image as they used to be called --which were minimally processed and were not compressed.

iOS does
