But these are all clearly right side up...

Is this an illusion post or a troll post? Genuine question.

The plates are all right side up. The main light is located off the right side of the scene. It casts a highlight on the right outside edge, and on the left edge of all internal edges. If one of the plates were upside down the highlights would appear on the opposite internal edges, but all of the highlights are the same.

Also the right edge of some of the plates casts a shadow inside of the dish. The edge of an upside down dish does not cause a self-shadow in the middle. Only concave shapes will do this.

They all look right side up to me, I'm pretty sure the shadows make it so it can't look upside down, I can't get it even to appear that way at all. I'm curious OP, with the famous dress, did you see black and blue or white and gold?

I've come across this image several times over the last years, but it only worked the very first time I saw it.

The shadows and perspective make absolutely no sense if they're upside down.

I feel like I've been bamboozled

How do I change them back?

Hmmm.

This sort of implies that our immediate understanding of sight is inaccurate until we analyze it more?

Fascinating

The shadows only work when right side up. I know this works for some shapes, but not these plates.

Which one isn't upside down? They all look like that to me.

That kind of worked, but they’re trays, not plates.

With some effort I'm now able to swap at will. The light part is the top, or bottom amd focusing on it allows me tp imagine the swap then excecute

I had to double check this was not a gif

omg my brain took so long to understand this picture X3 at first I had no idea what I was looking at until I read the text, then I had no idea y the hell upside-down plates would look like that and had no idea what material they could be made of or anything, then after like 15 minutes I FINALLY saw them upside-up (looking at the comments didnt help btw) and the image finally makes sense

all of these plates are upside down except for one that's actually a chiclets
