This just sent me down such a rabbit hole. Photo-light and graphs-drawing, like, at the risk of sounding like a stoned teenager : i was extrapolating from your comment in my head to like isn’t everything from our skin tone to the natural colors where we live in a sense photography. A very nice brain vacation on a Saturday morning quarantined on a grey rainy day

Related, there likely is a forgotten structure somewhere that worked as camera obscura for decades; perhaps a dark room with a single bullet hole in the wall, forgotten since World War 2.

Would be interesting if we ever found such a case where a discernible image got burned on the wall.

This reminded me of the “nuclear silhouettes” or “human shadow of death”:

I'm pretty sure I've seen some examples of this but I can't find them now. Besides the better-known pinhole photography, there is also pinspeck photography, and some random object standing in front of the wall could perform the function of the pinspeck.

Then how can you see and reply to my post?

Because I vouched for it first (requires some amount of karma I think).

Is this a normal thing for new accounts?

I really can't think of what I did to deserve a shadow ban.

From what I gather, there are some anti-abuse filters that can sometimes affect otherwise good accounts. When this happens, the best thing to do is vouch for the comments you think are good and contact the mods using the Contact link in the footer.
