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

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…

I'm going to tell your mother you said that.

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

I'm getting serious "you can build Dropbox yourself quite trivially" vibes here. I mean, people don't even turn their flash off in broad daylight…

The article is poorly written, as it only discusses the camera component. Strangely, they chose stock images of holographic and optical displays, but didn’t mention that even once. The Zeiss site is a much better read: https://www.zeiss.com/corporate/en/about-zeiss/present/newsr... In summary: 1) ZEISS unveils holographic Smart Glass at CES 2024, both for displays/projection/filtering, but also another component whic…

First, holy crap! Second, #3 is always a red flag for me. It is sometimes code for "we can do this in the lab but we have no idea how one would manufacture it." A similar analogy is "we've got this great idea for a program you can license but no one here knows how to actually code it up." Third, the impact of this going mainstream would be hard to underestimate. All those people working on transparent displays like t…

> Second, #3 is always a red flag for me.

Does Zeiss manufacture any public facing camera currently ? All their general public facing projects are collaborations with Sony or Vivo or other makers, and I think they only manufacture lenses, so nothing with a high quality chip in it.

It's probably another story on the medical side, but this doesn't fit a highly specialized, peofessional only niche with a PC doing the processor on the side.

There are already microscopic cameras that can be bought for thousandths of the price

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.

Since you can run a PI on that level of power it seems enough?

Am I alone in thinking this is cool but not inherently useful? The only use case where this might be useful is in video calls to make ‘eye contact’ more realistic but I’m sure there are software fixes (altering pupils) In most cases such as the windscreen you can just have a camera on the frame. Why does it need to utilise the glass itself?

> Why does it need to utilise the glass itself?

I think you’ll find that for a lot of people, it looks cool/elegant/stylish is a deciding factor.

For the people kinda worried: this is a highly specialized piece of glass that is extremely complicated to manufacture at present and must, due to the laws of thermodynamics, not be 100% transparent. It's not going to allow surveillance through existing glass installations in any form, just possibly new ones if there's room for the support equipment and through the use of 4-5 digit piles of cash. Any camera glass lik…

> due to the laws of thermodynamics, not be 100% transparent.

How useful is this statement though? Regular glass isn't 100% transparent either, even in just the visible spectrum. Shouldn't we be more concerned with the delta in the visible spectrum is if we're concerned about easy identification? (before mentioning that plenty of glass is purposefully tinted and dynamic tinting is an application here) And reasonably, couldn't we, theoretically, pick up a decent signal from simply capturing the reflections around the glass edge? I mean we can now do 3D reconstructions from pointing a camera at a mirrored ball. I'm sure it'd be very noisy, but there is signal. I mean to have the capability of projecting you'd have the ability to do the reverse too given that I doubt the internal structure of the glass would be (that) directionally dependent. Right? I can be missing something, it's been awhile since I've done optics.

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

It’s a bit uncanny valley though, right?

Nvidia Broadcast has a similar feature but it's really bad and completely unusable if you wear glasses. I don't have an iPhone to compare.

I'm super excited about whether something like this could be used to prevent bird strikes on windows. If anyone wants to grow the market for this technology there are likely square miles worth of glass that could have this installed to prevent birds from being killed.

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.
