Film camera (i.e. retro camera) notes.
Aww, got the film wound up all the way inside the canister? No worries, here’s how to pull it out, without a film puller. Er, well, maybe there are worries here. You really do need to have film to stick into the canister, as that will be the only thing that gives you the necessary curl and strength to complete the pulling.

Disposable camera? What does Wikipedia have to say about this?

So, I’m wondering. What kind of lighting instrumentation is used inside of a camera flash?

Wow, I certainly didn’t know that the camera flash had a much longer history and many more intermediary technologies than I originally thought.
So it is like you thought. The flash bulbs that you were looking at in your current cameras are in fact a kind of fluorescent light. Gas-filled tube that electricity is sent through.

Oh, but one important thing that I did learn about from reading the flash article is that often times, bounce flash is very important for taking good-looking photographs. Especially with humans, the human retina reflects red light directly back in the direction of incidence, which is why there is the red-eye effect unless sophisticated umbrella bounce flash is used.
Oh yeah, and bounce flash often times results in better photographs of still objects because the ambient light gives better shadow tones and distributions, or so I am told. So, for still 2D photographs, definitely yes, but what about for 3D scans? Don’t you want straight-on flash? Well, maybe not. Maybe you want consistent flash angle, and just rotate the camera independently of the flash.
Wow, and about flash safety. 80 uF capacitor? Really dangerous, and it too can get the problem of dielectric absorption that makes CRTs perpetually dangerous without proper grounding. And the exploding flash tube problem? Without a flash cavity and shielding behind glass, use of the device requires eye and ear protection. So should I be weary of long-term use of the flash in a disposable camera? Well, I guess that is an unanswered question. Oh, and some cameras charge the flash just by being powered on or by inserting batteries? Good thing my vintage cameras are not among those types.
