This is for all you equipment geeks who love your 10 fps motordrives!!!
I saw this story on CNN. Aparently some guy was disgusted by the photo quality of regular high-speed cameras, so he set out to do a redesign. What he came up with was a 12000 frames/sec motordrive!! I dont' understand the whole idea, but the gist is it uses a slit-shutter, and the film is moved past it at a constant rate.
At 12000 fps, a 120 frame roll that he uses lasts only 1/30. Still, the stroboscopic results he got of a water balloon popping over a guys head were truly great. I had to remind myself that this wasn't digital, but film. FREAKYYY!!!
My question is how does he know it's actually 12000 fps? Has he ran that many through it? If so Where did he get a roll of film that big? Yeah I know he can take what he did use and calculate what it would have been if he did have a roll that big, but I somehow think something would happen to alter it with a roll that big. It sounds like a gimmick to me.
This really isn't anything new. Back in about the ''50s, a scientist (forget his name) perfected the art and science of high speed photography. You've probably seen pics of his showing bullets passing thru apples, light bulbs, and playing cards. My local library has a book about him. I'll try to find his name.
I also recall seeing a pic made from a camera capable of shutter speeds of one millionth of a second. The pic was of a nuclear blast. There was a tall tower in the desert with the bomb on top of it. In the pic, the fireball of the blast had consumed about the top 1/3 of the tower, but hadn't reached the ground yet. It was pretty amazing.
Have you ever seen a TV commercial where, say, a strawberry (or some other item) falls into a bowl of milk? Or milk is just poured into a glass or bowl in what seems to be super-slow motion, with blobs of liquid surging up and down?
There's a type of high-speed motion picture camera that's been around for quite a while which is used to shoot those images. I saw a piece on TV about it some time ago. Two things that are worth noting: The camera only holds about enough film for a normal-speed run of just about 5-10 seconds. (Time such a scene next time you see one.) Secondly, the film runs through the camera so fast that it almost explodes when it reaches the end.
I wish I could remember even the channel I saw that bit on, but it was an evening when I was surfing, not paying much attention...
