Found this on a site that put all kinds of things under the microscope. This is actually a tungsten filament from a traditional incandescent bulb. No idea why it's so colorful but thought it was interesting! 

Interesting. I've seen plenty of filament closeups but this one is very 'colourful' as you say 

Isn't it "just" a colorized thermal image?

Could well be, yes. Still a rather pretty photo, though 

That is a really nice photo.

The colors could also be that the bulb is on and the camera is seeing some of the IR light from the filament.

Isn't it "just" a colorized thermal image?

What's the difference it's still a really good picture.
Why do people get so critical around here sometimes??

Neat effect, It probably make a nice phone screen wallpaper or a computer wallpaper.

I know for those technically minded think it's a rather trivial image but I think those making comments like that should read the room before commenting on posts like these IMO.

Sadly, it's my experience that too many people open their mouths before engaging their brains, hey, I do it sometimes, but such is life
