You can also just drag it to the right.

This is an extra step PIA. CMD-OPT-H hides all the windows and there's the desktop. My desktop is clean AF, so I know which icon it is. I open it in photoshop or preview, or I just drag it into the email I'm about to send.

If the metal bits are floppy enough it should add quite a bit of noise

poor PTZ mount :(

Video showcasing ISO noise behavior of a few different cameras: https://youtu.be/iiMfAmWbWSg?t=94s

Excellent presentation and explanation. I agree with ~90% of it except the small part at 4m54s where he tries to give an answer about the existence of noise. Yes, sensor readout noise and A/D quantization noise exist, but he forgot the big elephant in the room: photon shot noise ( https://en.wikipedia.org/wiki/Shot_noise ). Light is inherently quantum mechanical, and the lower the brightness of a scene, the more that the discrete nature of light shows up in captured images.

Lately I've been researching cameras for astronomy, especially for deep-sky objects (DSOs) like nebulae that require hours of exposure time. The marketing material for these cameras go into a lot of detail: quantum efficiency (the percent chance that a photon converts into an electron), dark noise at different temperatures (fractions of electrons per second), readout noise (usually around 1 electron), and well depth (usually around 10k electrons). Compared to general photography, the astro community much more motivated to explain and keep track of all the sources of noise.

That's a pretty good demo!

Very limited camera choices, though.

Yeah, it would be interesting and useful to see this across many more cameras.

dpreview is good for that. They shoot a test image of every camera on the market, and you can compare specific iso values on the same subject side by side.

Some of the new Nikon cameras have excellent high-ISO performance. Also, they now own RED, so we should see some interesting stuff, down the road.

Changing the ISO appears to scale the noise differently from the rest of the image.

Yep, just like a real camera.

True, but Google shouldn't be allowing obvious malware advertisements on their platform.

You could just send raw 802.11 data frames and then receive them with monitor mode on the other end.

If I had just re-read Neal Stephenson's Cryptonomicon recently, which I have, I'd say that I'd set up a link using WEP-encrypted 802.11b and hammer data across it with odd little bits here and there designed to generate maximum spy interest.

But then the actual message would be encoded by very slightly favouring the high or low end of the spread spectrum map as a kind of terribly slow FSK.

It seems that sometimes it fails to load the height map, try reloading the page. You should see terrain shading if it's loaded properly.

  "There are no 6K TVs available for sale to consumers"

This seems to be incorrect. What about the Samsung TQ65QN900FTXXC, which is claimed to have a resolution of 7680 x 4320 (8K)?

I think the point the article wants to make is that specifically 6K isn't used by consumers, whereas indeed 4K and 8K are.

How's this supposed to work for all the printers running tiny AVRs?
