Exploring Optical Phenomena on iPad

[bloby]

Hello.
I played with my new, first ipad yesterday. I inverted sceen colors and activated the cam.
How comes there is an image of me reflected in my eyes with NORMAL colors?

The screen view of yourself is inverted.
The reflexion of your screen view in your eyes is captured by the camera, and it is also inverted.
Therefore this image is yourself inverted twice, therefore with the same colors.

Everything the camera sees will get colour- inverted. So a double inversion is just what you'd expect. Having said that, though, I imagine what you saw made you wonder . . . . . . A nice experience when things like that turn up.
You get a similar effect (but spatially) when you use two mirrors to view writing. It becomes laterally inverted twice i.e. back to normal.

Simple and nice. Thanks.

Hello, it is fascinating to hear that you have been exploring optical phenomena on your new iPad. The phenomenon you have observed, where the image of yourself reflected in your eyes appears with normal colors despite the inverted screen colors, is known as the Purkinje effect. This is a phenomenon where the colors perceived by the eye shift when the lighting conditions change. In this case, the inverted screen colors create a different lighting condition, causing the colors to appear different in the reflected image. This is a well-documented phenomenon and is often used in photography and art to create unique and interesting effects. I encourage you to continue exploring and discovering the many optical phenomena that can be observed on your iPad.
