NBC News photographer Aaron Sasson tweeted this picture this morning:

@AaronSasson: More devastation from the hospital site in #Joplin, MO. #tornado http://yfrog.com/h8w1bioj

Aaron told us via email how he made this picture and what else he is up to:

I took multiple pictures with the iPhone and used an app called Autostitch. I use it ALL the time. I made a wide angle adapter for my iphone, and use that to take pics and video. Home made...yes. I'll have to post a shot of that too.

I've been shooting vid since leaving airport last night all through the process of getting to a breaking story and will cut it on imovie for iphone today and try to post tonight.

The other gear? Packed in dry cases and been shooting stills and video while hunkered down.
