iPhones solve the camera angle by changing the position of the pupil in software instead.

Which versions of iphones do this?

Any model newer than iPhone X (XR/XS and up).

It's a Facetime exclusive, though - no API so other videoconferencing apps can't use that.

I never understood bigger and more numerous camera bumps until I used optical zoom and took photos at night. Image quality with thick lenses is incomparably superior to that of thin lenses and 3 image sensors collect 3x as many photons as 1 so you don't have to hold the phone still for such a long time. Ideally the entire backside of my phone would be lenses

and your 1500€ phone still sucks compared to my 500€ DSLR, lol

The best camera is the one you have in your pocket when you need to take a picture.

Yes but I have my iPhone everywhere and the pictures the 15 pro max takes are beyond ‘good enough’. Even the zoom is pretty good nowadays. Often the choice isn’t iPhone photo or DSLR photo it’s iPhone or no photo at all. It’s a right faff getting the DSLR out and carrying it around. I brought mine to NYC over Xmas and ended up using my phone mostly. Also no one I know prints photos out, they look at them on their pho…

I tried to go on holidays with my dslr… what a pain. So heavy (unless you buy a $3000 mirrorless) for photos I never print and the times I print them no one ever take the time to look at them. They stay in a closet until thrown out. The quality from my iPhone is not that great as a 4K monitor wallpaper compared to my DSLR. But given the fact that it weights nothing and on holidays the iPhone allows me to text, use GP…

Just buy a used mirrorless camera, it’ll set you back a couple hundred, not 3k.

New technology is fun and all, but even decade old digital cameras are more than good enough for good holiday snaps that you might want to crop and print.

For the everyday needs of the average non-enthusiast consumer, I'd argue that an iPhone is simply better than a DSLR or mirrorless - not just more portable or more convenient, but capable of producing reliably better images. Sure, the DSLR is the obvious choice if you're a serious photographer, but most people aren't serious photographers. If they buy a DSLR or mirrorless camera, they're going to use the kit lens and…

So we should call those shots snapshots when made on a phone. Well, the only thing you need to know when shooting with dslrs is to move the dial to Auto/P. If you want to play with DOF, move it to Av. If you want to shoot the dog, move it to Tv and 1/500. If you want to shoot an airshow move it to 1/1200 or higher. Is that too much? :D

Buy any compact camera with a 30x optical zoom and it will take better pictures than a smartphone. Maybe not all of them, but you can zoom on details from a distance, take pictures of animals that would flee if you try to get close, etc. The last one I bought about 10 years ago was about 300 Euro, maybe 200. It has wifi to backup pictures to my phone.

Yeah it sounds like a great option to place a camera invisibly in the middle top half of your screen so you can actually look a person in the eye when videoconferencing. No more weirdly looking down or to the side for everyone. I'm sure it can be used for creepiness as well but I see the benefits too.

iPhones solve the camera angle by changing the position of the pupil in software instead.

Having the screen be the camera 1) removes the need for the holepunch as well as magic island workaround 2) could clearly be used in tandem to improve the effect, even potentially reducing the required computation. Sure, Google also fixes images in post, but that's still not a substitute for better cameras. You're always information limited.

This looks really cool. Could you put a polarizer on this and have that filler out the other side of the display, so a smart window is one way visible? That could make smart glasses and headsets much better.

I doubt you'd even need to. The fact that it's not a uniform grey blob means they're already controlling how the light leaves the device. I suspect it's already directional.

I agree with everything you said, but the example on the CES floor does not have an apparent tint.

I assure you it is semi opaque. A one way mirror is a primitive example of this. You can make the reflection increasingly transparent but it will be tinted up until the point it doesn't reflect anything. It may not be noticeably visible to the human eye under most lighting conditions, though.

>> but the example on the CES floor does not have an __apparent__ tint.

I'm not sure you two are disagreeing. Seems like you're just reinforcing their point. I mean if someone said glass is opaque and their evidence is that you can't see through glass and your evidence is to point at UV light... well... you'd be technically correct but you're talking from a different ballpark.
