I know, I know. Last "Photo of the Day" was a shot of the city, but I just couldn't resist. We've had a couple monster storms come through Chicago over the past week, and the last one really provided some amazing scenes. As crazy as this photo is, you really had to be there. Imagine hearing a tornado siren (think off-tune nuclear siren - really spooky), watching a full double-rainbow appear, and seeing the sky light up with multiple lightening bolts - all at once!

*UPDATE: Insane HD video of this storm... must see!

Bonus picture and photo description after the break:

Camera: Nikon D90
Lens: Tamron 11-16mm F/2.8
Focal Length: 11mm
F-stop: 3.5
This shot is actually comprised of three shots in bracketing mode and then combined using Photoshop CS5's HDR Pro tool. The outside lightening bolts are from the first of the three shots, and the middle bolt was from the last. After playing with the HDR settings, the photo was then re-edited in Photoshop and iPhoto.
