Some more UV fun :
Left and right ones are modern glasses while the green is an old one (before 1950 for the least). Of course they are all neutral white glasses and don't have any special color under visible light.
Exposures have been adjusted, with bare eye the green and blue are very bright, while the rosy is very shy
The pale rosy tint doesn't come very well on the picture (a bit too much on the violet side) but at least i tried
I use the single uv emitter on my X80 to see just how much synthetic fiber is on my house walls as my wife doesn't believe in cotton anything. I think she was more shocked than I was when I lit the wall. It's almost scary that we breath in so much of that stuff on a daily basis.
Do you like fruits ?
Mmmm looks tasty !
UV (black) magic :
Still want some ? ;-)
No pictures of your bathroom? 
You don't really want to see that ... and neither do i :p
