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

Your 500 euros DSLR sucks compared to my 1500 euros phone for gaming. Do you carry your DSLR in your pocket every time you leave the house? These is obviously a matter of specialized vs general use.

Wonder how long intelligence agencies have had this.

They'd probably put it in lightbulbs (to get a long lasting power source and good viewing angle).

They'd probably pay a contractor $60 million to develop it for the military and not actually wind up with anything of use

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.

Which versions of iphones do this?

Years ago I was able to visit Zeiss in Oberkochen. They had a fantastic headquarters with a few older lithographs. I think a couple of the instruments were 80 millions dollars or so. There’s a facility across from the Autobahn that was so sensitive trucks going by would throw off their machines. They had to put padding on the autobahn to prevent it. This was after they put the foundation on some kind of suspension. M…

Feels like it would be easier to buy land not next to a highway :-)

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 regularly use my DSLR and print photos with my own canon photoprinter. i bought a 70mm-300mm lens for a bronyconvention (galacon) and it is simply impossible to get images of that quality with a phone.

and the 50mm f1.8 is really great considering the low price.

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 GPS and google maps, play, read articles, watch videos and allows an immediate editing of my photos in raw and created a shared album right away … it’s a no brainer anymore

It's a reverse light guide. We've been beam forming for a long time, it's unsurprising that the reverse is possible (imaging through a light pipe). The principal issue will be gathering enough energy. A well lit source like a bathroom mirror (mirror behind the light guide) could work pretty well I'd wager. If the light guide is too efficient then it will appear opaque, so there is a trade-off. I find "turns any windo…

jiminy christmas!!!

I lit (pun) came to gripe about light pipes...

However here is you solution:

3D print lenses in a header for threads to be arbitrarily placed in a [COMPOUND] lens and pull that feed with AI spatial mapping (yes these are easy now)... EYE

And you can make these in many increments - micro even... "Hey NSa, super simple optical prince Rupert drops on a composite eye" (self destrucing fiber lens when discovered)

Nah, this will only be good enough for sensor-level power (like 5W from a whole window). Only useful in very limited circumstances. It's not going to replace normal solar power.

but like, thats enough for the camera to power itself. pretty cool no? we can deploy this tech without plugging it in.

>deploy this tech without plugging it in

you mean because it can also power a wireless transmitter or a large memory array storage? cuz a hologram that's not "plugged into something" might turn out to not be that useful.
