comment Are full-frame cameras less forgiving with respect to camera shake?
You seem to be using "APS" to mean "35mm full-frame", but that's not correct. APS was a film format that allowed a variety of aspect-ratio crops (APS-H, APS-C, APS-P), but they were all smaller than the 24x36mm frame size of 35mm film. en.wikipedia.org/wiki/Advanced_Photo_System

comment Can I ask Lightroom to delete copied photos from the SD card?
"Move" is not available for me when importing from SD card (unlocked), USB flash drive, or iPhone 5. Using Lr 5.3, Windows 7.

comment How do I identify unknown thread mounts?
Followup: I bought the bellows back then (for two whole dollars) and it sat on my shelf since then. But I recently bought a few M42 cameras and lenses at the same thrift store, and they fit, so it was an M42 bellows. M42 adapters for my cameras are on the slow boat from Hong Kong as we speak.

comment How do I convert focal length to maximum distance?
"How far away can it see?" is a weirdly common question about binoculars, telescopes, lenses, etc. I usually point out that your unaided eye can see as far away as other galaxies.

comment What are the challenges of creating a pinhole camera with short focal length?
@ysap Pinhole cameras suffer from "natural vignetting" (the cos^4 law) no matter how thin the material is. You get two powers of cos(theta) from the inverse square law (as the OP points out), one power from the light illuminating a larger film area off-axis, and one power from the hole "looking" smaller off-axis. cartage.org.lb/en/themes/arts/photography/photproces/…

comment What causes faint circles in astrophotography images?
If that is the cause, a light-pollution filter should help by blocking sodium and other common emission lines.
