Re: Nikon makes firmware for astronauts to block cosmic rays in photos
#2digital cameras carried on planes in the early days had cosmic ray issues too. So they sent them by boat. Hell. The ones today do. This is a weird article though. A lot of cameras compensate for dead pixels and cosmic rays.
It should also have been designed in every camera to have unique file names. It’s ridiculous they all don’t.

If you use a Sony A7 series camera, every month, the camera will take a picture upon shutting it off, which it uses to remove dead pixels/hot pixels - you can hear it, actually.
If ever you have a pixel die or get stuck, you can also manually set the date a couple months ahead and turn it off - it will most likely be fixed when it turns back on.

So THAT is that mysterious click-clack of the shutter that randomly appears on my A7S2. I've been putting off sending it in for repair, but now I can completely avoid that. Many thanks!
Do you happen to have a link to some documentation for it?

#5It’s a poorly written and badly explained article. The first comment does a great job of explaining why, and how the new “firmware” actually works

As far as I know, there's no official documentation for it, but people noticed that it happened every month and that it would fix dead pixels (for example: https://www.4kshooters.net/2015/12/01/an-easy-trick-to-fix-d...)
I personally used this trick twice to fix dead pixels on my camera, so I can attest to that.
For cameras without a mechanical shutter, there is instead an option to do it in the menu, for example : (https://helpguide.sony.net/ilc/2010/v1/en/contents/TP0003229...)

A manual sensor clean in most cameras does this. If mirrorless, leave the cap on
Re: Nikon makes firmware for astronauts to block cosmic rays in photos
#8The noise reduction they're referring to is dark frame subtraction used for thermal noise and defective hot pixel removal (the latter is what the ISS has to worry about.) Numerous cameras from other companies allow for forcing that on at any speed via menu options, not just slower shutter speeds.
I had this feature available on an early 2010's Olympus. They called it "Noise Reduction" (not "noise filter", that's different) and it could be set to off, normal, or "on." On makes it behave like this "special" Nikon firmware, always performing the dark frame subtraction. "Normal" applies some logic based on shutter speed and ISO, and off turns it off completely. Manual dark-frame calibration was also available via the menus.
I'm not sure why Nikon is tooting their horn so loudly about adding (only for people in the ISS) what's been available to earthbound users of other camera systems via a menu item for a decade?

Many cameras have a menu option to trigger a dark frame calibration. Been a thing for a long, long time.

It's not about dust on the sensor, it's actually software that maps dead pixels to fill them in every time you take a picture (as well as dark frame offsetting, presumably)
