RGB to CMYK
When in Krakow I visited the Museum of Illusion, where I was delighted to encounter this "optical illusion". On the left are three lights in red, blue and green. On the right, shadows are cast where one of the lights doesn't reach the wall: and so the shadows are cyan, magenta and yellow.  |

Interesting Steve. Why does this happen? And why is that big watermark outside the window? |

Re: RGB to CMYK
Makes sense. Where one of the three colours is missing because it is shadowed, the resultant shadow area is lit by a mix of the remaining two colours. Obviously you don't need telling that, so I am not sure if you are simply pointing us at a rather neat demonstration or testing us? _________________ The subtlety and conviction of any Photoshop effect is invariably inversely proportional to the number of knobs on it ....... |

Re: RGB to CMYK
Thats interesting. It makes total sense but never actually realised it would work in reality. _________________ The grass is greener on the other side of the fence because there is more $hit there. |
