Laser

Low power green laser photographed head on through an aperture of about f/175 (pinhole/no lens).

Exclaimer: Take care with lasers and never view them through the camera view finder, always use the LCD screen. You don't want any laser no matter how low powered to shine directly in your eyes.

No, indeed!
Very inventive and cool!

That is truly extraordinary. I don't know if it's just my screen but the green seems to pulse in and out of itself.

Laser! I tried a laser pen shot the other day. It was really rubbish though. This I like.
