This one never works for me. It’s always face up the whole time

It never works for me because there is not really a reference point. All I see is schrodinger’s plates.

No, they’re face-down in the thumbnail, but face-up in the full-sized image.
Edit: NVM the ones in the thumbnail flipped

Perhaps it would help some people to imagine where the light is coming from first? If the light is to the left, they’re face-down; if the light is right, then the plates are upright.

Once you see the shadow on the middle left flat big plate the light must be coming from the right (curve of the shadow is wrong for it to be it’s own shadow), so the plates are upright.
