People tweeting stuff. We allow tweets from anyone.

RULES:

  1. Mark NSFW content.
  2. No doxxing people.
  3. Must be a pic of the tweet or similar. No direct links to the tweet.
  4. No bullying or international politcs
  5. Be excellent to each other.
  6. Provide an archived link to the tweet (or similar) being shown if it's a major celebrity, figure or any politician. If you replace the "x" at their site with xcancel (so it beomes xcancel.com), and you're not on mobile, it will save video. https://web.archive.org/save is another great option. Archive.is is no longer recommended because they remove/alter content.

Would the grain show up in digital pictures as well or only on film? I know why it appears on film but the gnomes that work my cell phone camera won't give me a straight answer.

I don't think it would look the same, if it was a CMOS sensor, I think you'd see lots of bright white pixels

IIRC radiation would cause grain on a cell phone camers.

Pretty much, but highly dependent on the energy of the ionizing radiation. Lower would come out as a dull grain, higher would show up as bright spots. Neither would look like this post though lol

Not exactly the same, but an electron beam puts a lot of noise in the image: https://youtu.be/Uf4Ux4SlyT4

Also I've heard the international space station gets a lot of dead pixels on their cameras from cosmic radiation.
