Ultra high speed photography

[newbuckeye]

The revolver pics are really cool!

Wonderful.

What was the Camera and film speed (or digital equivalent)? I have often wondered about the sensitivity of the imaging plane.

If this was film, what film did you use?

Notice the tiny fragments of lead in the picture of the pellet leaving the barrel of the air rifle.

 

[Arkansas Paul]

That is extremely cool. I think the first pic is my favorite. Awesome!

Typically iso 800 f5.6 at 10 feet
Using a nikon d90 (aps c sized sensor)

Are the plans for the triggering mechanism on the web?

 

[Agsalaska]

Wow. Beyond awesome.

Triggering is not unlike: http://www.arduino.cc/en/Tutorial/KnockSensor

Those are some awesome pics!

Awesome!! Can't wait to see more and read about the project. I would love to set something like this up!!!

See this link for all details on the setup.

As I am suffering from a dearth of imagination and cleverness I will add my WOW!! and AWESOME! to the mix. Great job, some of the best pix I have ever seen.

I knew it was theoretically possible, however, I never took the time to set everything up to try it.

I was going to use an electronic "trigger" by placing two wires each clipped to a sheet of aluminum foil. Then, put a piece of waxed paper between the aluminum foil and shoot through the layers, in hopes that the projectile will make the two sandwiched sheets make contact with one another.

I like your microphone (adjustible) better.

Amazing Post. Very cool and interesting. Waiting for more such cool Ultra high speed photography .

That's amazing man! Is that their largest size? I'd love the colored pencils pic as my desktop, if you've got a larger version!

Here is a 3 megapixel version (2048x1360). The original is 12 megapixel and covers the same view.
All pencils were hit. so the bullet tip is actually inside the yellow pencil already:



All pencils were hit (so the bullet is acutally inside the yellow pencil).
We used the remains for a second, but poorly focussed and timed shot (where is my green pencil!?):

Thank you very much!

The shock wave on that last picture is still awesome, for a 'messed up' picture.

 

[amateurtje]

I think it is mainly gunsmoke, since the muzzle was quite close, but it still shows the bullet is coming in at a very high speed.

You might want to try setting up the flash to make the bullet cast a shadow on a plain background. The shadow graph will show the shock waves being pushed by the nose and base of the bullet. Worked for EG&G and took a summer course at MIT from Harold Edgerton in high speed photography - the shadow graph was one of the first projects we had to do.

Did you use a special point source flash?
