The Physics Of Projection Fails
The commenter just discovered the fascinating physics of light projection! When text on a transparent visor is read from the outside, it appears normal. But when that same text casts a shadow through the visor onto a surface (in this case, skin), it follows optical projection principles—creating a reversed, flipped image. It's like a mini camera obscura effect happening right on someone's chest. The person's scientific observation is spot-on—the projected "Espresso" shadow should indeed be upside down and backwards according to basic optics. Someone skipped their physics homework when designing this photoshoot!
