Taking photos at night on your phone used to look terrible, but recent phones have much improved capabilities. Julian Chokkattu, reviews editor at WIRED, explains how smartphone camera technology has gotten so much better.

While I love what the technology can do to enhance photographs I have reservations on the influence machine algorithms processing have on what we -see-. Photographs were originally considered objective incontrovertible records of reality. Gradually we learned that images can be manipulated, first crudely by analog means, and increasingly with greater sophistication by digital. By going beyond what we are physically capable of discerning, we increasingly add subjective interpretation. In this case the subjectivity of the programmer/algorithm. This is fine as long as we understand it is a -hallucination- as the MIT professor stated. I think for most people however they will accept it as a new reality. This is where the danger may lie. Would we accept an augmented and highly processed night vision photograph as legal evidence? Will our real but limited visual perception be considered inferior to this new augmented reality? The augmented view, subject to subtle biases, adds to our already warped perception of reality. I think each photo should have a pop-up disclaimer: -For entertainment purposes only-. Not to used as legal evidence. May cause disorientation. Some people may experience this as a hallucination. -

The irony, for me, in any voices railing against the 'fakery' of the involvement of computing/processing - is that my Samsung phone captures the view that _I am seeing in front of me_ - it's as though it's behind my eyes. A DSLR in contrast, out-of-camera at least - is 'dumb' - & I'm stuck with the old-fashioned dilemma of choosing which areas to expose for - the sky, or the darker foreground (I thus use spot metering a lot. My own eyes & brain creates massive dynamic range - these smartphones are achieving this. So - you need all this AI to recreate the scene authentically - ironically.
I say all of this as a DSLR enthusiast!

Colour reproduction on cellphones is bad. I live in the southern hemisphere but the phones are designed in the northern hemi and they just don't capture southern hemi colours. I have friends in the northern hemi who both use real cameras and whenever they come to the southern hemi they use different film stock. They both use Kodak film in the north and change to Fuji film when visiting the southern hemi, as Fuji reproduces the greens and blues, in particular, more truly, so it can capture the real colours of our oceans and turquoise rivers that have limestone beds. You can't do that with a phone.

Part of me wants to decry all the image processing and compositing as so much digital fakery. on the other hand, I can't help but wonder if it yields something that is actually more representative of how our brains remember a scene than a single static image of one instant in time at a fixed aperture/focus/shutter speed does. the human brain is a pretty great integrator, after all.

When a smartphone can actually produce an actual optical shallow depth of field on portrait mode (blurred background) that's when I would take Phone photography as a professional. They would need to somehow break the laws of physics tho, or create a new way of capturing light instead of what we know as camera sensors.

After the iPhone 6 all the cameras on iPhones have horrible lens flare and makes taking photos in low light with any strong light source impossible, which is all of them. I can't speak for Android phones, but the last good iPhone camera was on the 6.

I appreciate my cameras ability to take photos closer to what my eyes see. But I disagree with dude, I do not want my camera to turn a foggy day into a sunny day so I can show off my perfect beautiful life. I mean vacation

Most of the consumers don-t have an ability to shot great photos and editing to look eye catching images- I don-t think it-s not an illusion like what you said it-s innovation make life easier and time saving for everyone.

Other than that, small sensors have gotten a lot more sensitive, and companies are putting faster lenses on phones. On top of that the photo app has gone full skynet in terms of computational photography.

Isn-t the processing essentially the same as fill stocks giving you different looks, color and grain? Cinematographers shoot on various stock depending on what they want the scene to feel like, no?
