camera (not wind, not home-depot) "SHEARING"

 Way down in another entry they briefly mention shearing in a camera (not home depot or a plane) 
And I can't find it.
*Maybe* it's a slanty effect... a woman sitting upon solid ground now looks like she's going up a steep hill, thanks to shearing (on purpose.)

A truck on a highway taking pictures of another truck, shows a very slanted truck.
"Slanted" is kind of impossible so I'm assuming it's another example of shearing.


"Focal Length" affects shearing, (I think), that's not saying what it is, just how it works (I think)
And a totally Modal paradigm thing explains:

People *like* shearing
and ask and present pages on how.
(and software programs emulating it)




The time-delay-shearing defect is a LOT harder to find (like the truck)

(well because, it would take a really professional photographer to see to it that nothing is just blurred...) (blurry blobs blinking is what the whole brouhaha is on about...)



"slow Readout speeds" they didn't cover that in my book yet.
shit. It's like people try very hard to make all this complicated...
Me googling "shearing" is asking too much of the AI engine, it blathers on about earthquakes and steel-beam strength, 
and narrowing it to shutter-speed makes it go all, 
"O! You want to talk shutters, well!!" 
And it launches a bombast of defects in phone-shutters.
One guy has his electronic shutter take multiple pictures and wonders about the
"warp"(?) 
"You have a shitty shutter," compared to upper-crust.

(put Some really nasty meaningless phrase here)
Beeesides,
*Mine* is 21 24mm(?) ois pdaf, grrr.


I'm still learning about "photobombs"




No, I despair finding camera-produced shear, or the reasons the (original, as-is) picture is desirable or undesirable.
It must be one of those esoteric things only known to a select few scientologists in the illuminati...
