In theory what prevents me from using a huge lens and sensor on a DSLR or a mirrorless camera and then using the same advanced software but now running on a desktop computer or a server that is many times more powerful than a smartphone to do advanced post processing?

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…

But that CPU shouldn't really do anything other than shoveling raw sensor data to flash as fast as possible. All the processing can happen on your workstation (or an iPad or whatever).

Well it’s in telephoto and 1/121 exposure so the photographer was probably wobbling around like mad when it was taken and the overlay and computational image stuff got confused. I’m fine with this. I use a mini tripod with my 13 pro on telephoto. Back in the old days this would just look like ass instead.

I would rate any camera that does this as 1/100. It cannot possibly be a worse camera. How anyone that have an interest in photography can see swapping a head with a leaf as just fine is beyond me. It's no better than using Snapchat like filters and calling it raw. It's is utterly broken and should be removed ASAP from all iPhones.

I’ve taken about 8000 photos from iPhone 6 to 13pro and sifted through them all manually within a day or so of taking them and haven’t seen any anomalous things yet.

The error margin is tiny and the benefits to the output are huge. My brain has more trouble accurately portraying things. This is not much of a problem.

Reality is really transient and inconsistent anyway.

You can set Apple's devices to shoot RAW, and it's usually pretty great, without the painting-like qualities of its default image processing.

How raw is “raw”? If you take a long exposure in a dark room with a recent iPhone you can see the long exposure shake being removed and the picture coming out a lot sharper than it should. Would a “raw” version of that photo be a traditional long exposure or would it be the clever stacked image but with less post sharpening etc? Or is the raw even a short video sequence? (that would actually make the most sense) I ha…

If you use a third-party app like Camera+ to shoot RAW, then it is the raw, completely unprocessed sensor data as a DNG file, like any DSLR. Shooting RAW on the ultra-wide camera in a dark environment results in a completely unusable image.

If you use the iOS camera on an iPhone 12 or newer and enable the "ProRAW" option (which is shown as just "RAW" in the camera), you get a processed image, but with the data used as a base for the processing intact for re-processing when you edit it.

I recently got a Pixel and was disappointed to see that the stock camera app has no way to control the focus manually. I guess Google is so impressed with their post-processing they think users won't need any control. Turns out, their software isn't that great at focusing in many of the photos I take, so I need a different camera app. My only requirements are: 1. Manual focus 2. Wide angle lens support I thought a re…

Does Open Camera not show the switch multi-camera button on your phone? From https://opencamera.org.uk/help.html

Switch multi-camera icon - This icon only shows on devices with more than one front and/or back cameras, and allows you to switch between those cameras. For example, a device might have two back cameras, one standard and one ultra-wide, this icon will switch between the standard and ultra-wide camera. If Settings/On screen GUI/"Multiple cameras icon" is disabled, then this icon will not show; instead the "Switch camera" icon can by used to cycle through all the cameras. Note that some devices do not allow third party applications to access their multiple cameras, in which case Open Camera isn't able to use them.

The camera moving?

Then increase the rate at which frames get captured since the video is destined to be ≈24-30 fps anyway?

But the higher the framerate, the less time you have for exposure on each frame.

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

It’s what you desire your skin to be .

That might be good for myself, or if I’m honest even my wife, but my daughter looks perfect to me and I only want to see her in reality.

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

You guys are conflating 'adjusting light levels and sharness' with 'replacing whole objects in one area of scene with other objects from the scene' I think this particular big demonstrates a massive gap in what people think photoprocessing is, and what it has very recently become

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.

The "hard requirement" is just multi-frame noise reduction, which has been around for a lot longer than the AI/ML hype wave, and has always had a risk of producing similar artifacts to this one.

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…

> It's impossible to just 'enhance' an image to make a license plate readable. Well, a phone can reconstruct this license plate, and in fact any license plate in lieu of this one! And invent a new one! Which is worrisome for justice. Presenting proof, that was uploaded to servers, horodated and geostamped, won’t be enough in a court of law. Anyone can answer: “What if the iPhone recreated and inferred the presence of…

That has always been the case for photographs from every device that has ever been capable of recording images.

This reminds me of Huawei camera app detecting pictures of the moon and superimposing a clear stock photo into your picture: https://www.androidauthority.com/huawei-p30-pro-moon-mode-co...

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.
