Before we criticize, before jumping to conclusions -- I just want to point out, it is a great leaf. Are we certain that the camera's decision was wrong? I mean, maybe we should consider the camera's judgement about what the best picture is. I'm not a photographer, if my camera tells me that my friend's head is best represented as a combination of sticks, leaves, and other natural objects, who am I to argue with that?…

I also don't quite understand the leap to controversy, which seems to rest on the assumption that this person does not have a pile of leaves for a head.

Right. To me the photo was set up for the retweets and likes. They got their leaf-headed friend to stand in front of some leaves and took a photo. Probably didn't even use an iPhone. This might have been some Samsung psy-op to discredit the iPhone neural processor.

Why does everyone automatically assume this explanation is correct? Based on the photo, it looks to me like a real leaf in the foreground, probably having fallen at the perfect time to create this photo. I would be curious to hear Apple's explanation on this...

Few things seem to be at play here.

1. iPhone uses face tracking to adjust focus on subject's face

2. Same face detection can end up detecting faces in arbitrary objects. Very common occurring. Here the leaf.

3. iPhone uses multiple lens to compose a single photo. 1 lens focused on the persons face while another with better focus on the face estimated the face to be within the leaves.

4. The composite photo now has picture of leaf replacing the person's face.

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 never has been accurate. Even on dumb traditional cameras, colors are more of an interpretation than a reality.

Hearing this and Steve Jobs’ critique of Microsoft, “they have no taste” is stunning. Taking the iPhone as the mass consumer computer, must mean that as a computing device the iPhone has very little taste… Which in a sense I can definitely see…

iPhones are definitely aimed at the more discerning, up-market customer. Android meanwhile is for the mass-market. iPhones have four levels of encryption designed to thwart the likes of the FBI trying to get data out of your confiscated phones. Androids have a checkbox tick that basically says "Encryption: Yes". iPhones have 1000-nit OLED HDR screens that are colour-managed and calibrated out of the box, and have Dol…

wtf is dolby-vision HDR? Sounds like cheap marketing crap like “Extra Bass Boost”

I rock an iphone because the SE is cheap and the camera is good, if I cared about privacy I wouldn’t have a phone with always on microphones and cameras…

NSO group’s Pegasus was cross-platform, so as far as I’m concerned the security point is moot, people buy iphones and androids for various reasons, and it’s easier to judge someone’s “upmarketness” by the stickerprice of their flagship, not the OS it runs…

iOS does

How do I get this? Sick of seeing oversaturated landscapes. Edit: why is this downvoted? honest question... I'm on iOS and didn't see anything in settings.

Some models of iPhones the "PROs"[1] support something they call "Pro Raw" which isn't actual RAW images: "Apple ProRAW combines the information of a standard RAW format along with iPhone image processing, which gives you more flexibility when editing the exposure, color, and white balance in your photo."

So it's better than JPEG but not as good as RAW.

Anyhow apparently Apple supports quasi raw at the system level but doesn't always get exposed to the user. but 3rd part apps can take advantage of this even for non "PRO" Apple telephones.

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

Film camera?

"Cameras" making changes to the image like this make the discussion about the image processing pipeline during the Rittenhouse trial seem a little less bizarre.

Any technically savvy person should be able to differentiate different types of upscaling algorithms.

The judge was arguing about enlarging an already recorded video, not about the merits of the original recording. This post is about image processing during the capture process.

Conflating them is disingenuous, unless we're taking very large leaps of logic

> 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. Can't replace sensor area with anything other than more sensor area. Week ago I got the perfect demo of that when I filmed a happening at around 10pm with only some dim garden…

With video you can’t “cheat”. You can’t gather up a second of frames and stack to one photo. That’s what phones to quite well. You only have 1/24s (say) to get the shot before you need to get the next one. I bet an Iphone12 would have made better stills than my aging canon 60D which I try to keep at 1600 or lower. And that’s pretty remarkable to be honest.

the iphone 12 has no depth of field so a larger sensor is anyway much better. there is no way around it. You cant hack your way to photography.
