I am not sure what you are trying to say here. They definitely did not ask for their face to be replaced by leaves either. Is it either unmodified, or leaves? Is not there a middle ground?

This is the "smart HDR" option on an iPhone, described as "In difficult lighting, the best parts of multiple exposures are combined into a single image". So there is the middle ground of disabling this. Or, alternatively, just not caring about such an error once in a million shots. (as an aside, I'm pretty sure the structure of the leaves is responsible for this error, as it's an area with usually many strong edges i…

Yeah. If I tap "Selfie" on my stock Android 11, I can see my face being smoothed out. I can tell that it is modified. If I have an issue with it, I can disable it. :)

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.

Reality isn’t good enough in the time of Instagram. People want perfect pictures to reflect their mind’s eye. In a way this is the way in for a metaverse. Reality isn’t what they seek. They seek an alternate state that is a mix of reality and fantasy.

Hypermediocrity in the flesh. I expect the depressing outcome for most is to discover that despite having traded our flawed execution for that of a computer, most of us can't even conceive of an existence masterful enough to be worthy of accumulating the abnormally high social status we seem wired to crave.

They asked for their phone to make a best effort to stack many pictures into one, cleverly aligning objects as well as possible. And the camera failed. The alternatives would have been an extremely dark picture of a person without a leaf-face, or an extremely blurry picture of a person without a leaf-face.

If that truly is the case, then.. woah. It definitely failed.

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…

I’d be curious to see this, could you link to some examples? Cheers.

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.

It’s what you desire your skin to be.

Yes, yes really. When real resolution is being substituted with the best guess of a completely closed source image processor, the court should be made aware of it.

This sounds like a weird rationalization for an absurd case of technical ignorance. Like when people defended nuking hurricanes or using UV lights as a Covid therapy.

If a camera can replace a head with a leaf nothing taken with that camera can be trusted, especially in court, ever. Any changes to photos or videos should be avoided. This is the norm in court cases. You should read a proper article about it instead of the click baity ones.

I don't understand, why is this ruled out? Assuming that phones reach a point where this is computationally cheap, what would be so hard about having a sliding window for each frame in the video?

The camera moving?

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

I don't know if digital camera emulation is a thing, but this thread is making me thirsty for a way to emulate my old 2MP Olympus.

I have some software that has "digital film" emulations (DXO FP), I suppose that is what they mean, emulating old cameras.
