The camera bump on a cell phone is a first world problem.

Heck, I don't even know what a camera bump is.

>>Jeff Lundeen: People lug around large cameras with huge telephoto lenses.

Large cameras (especially film) have larger capture.

And not all lenses are the same.

You can have a “versitile” lens but a dedicated high performance lens (for low light, for distance, etc.) can be more suitable. Depends on the task.

I heard a millennial talk radio host joking about the “old tech” of the camera used by the astronauts on the moon. “So big like something from the 40s”. They weren’t going to have much opportunity to go back and get more high definition captures ergo use a camera with a larger negative. Probably also needed to keep moon dust out of the camera.

The article is vague on what a ‘spaceplate’ is. I suspect it is a Metamaterial with a negative index of refraction. Last I heard that had been achieved with microwaves but not yet with optical light.

I can’t quite discern if this is an improved GRIN (GRaded INdex) lens, a nano-Fresnel lens a combination of them or what?

That being said I do have an immediate application for a sheet of paper thick microscope...

Camera bumps and being misgendered. What a terrible country we live in.

I want to see a square mile telescope or, what the heck, a ten square mile one. Weight won't be an issue anymore, just the price of land.

I remember those lunar cameras, they were Hasselblads. They took large-format roll film. You could get great low-light shots with Tri-X-Pan film.

What's cool about the cameras in modern phones is the sensitivity of the CMOS camera element is so great that the f-stop of the lens is high enough that you get a pinhole-camera effect and things can stay in very sharp focus even in fairly low-light.

Something various countries German scientists pioneered back in the 60s except with film emulsions?

I guess I ought to sell my GH 4 and related since I never turn it on anymore. Ditto the GoPro as well. It’s been a couple of years since there’s been any real reason.

Photography and videography used to be enjoyable plus I made a little extra money sometimes.

My two cents: their explanation is atrocious. Before they release this thing they need to hire some marketers who can explain what they did.

I think what they are saying is that a normal lens takes a beam of light, and depending on its location (near the edge, near the middle) bends it to land on the right spot on the sensor. The problem is that you can only bend it so much, so you’re going to need a good distance for the bent beam to travel before it arrives at the right place.

This lens seems to take a particular beam of light regardless where it hits the lens — only just considering the angle it’s coming in at and moves it over to land on a particular spot on the sensor.

Such a telescope located at the Lagrange point between Earth and moon would be very cool :-)

When I got married back in 02, my ceremony was the last film job our photographers did. They moved to digital rather grudgingly. Old school film artists who did beautiful work.

They were eventually crushed in the time of the win like many and to find other lines of work.

My Samsung doesn’t have a bump. Should it?
