It is amazing what you can do with a little vision, even if you are pretty tied by budgetary constraints. Nate Powers and his team of students pushed their budget, and skills to the edge to create a low end (though high value) dancers bullet time shots. The challenges and work frame on this project were quite different from the ones described on a previous crowdfunded bullet time shoot, so I asked Nate to share a bit about the project.
Taking a 360 degrees panorama is a cool thing on its own, but taking a video-lapse takes it to a new level.
Hugo Baptista created an interesting clip they call a panolapse. It is a combination between a timelapse and a panorama done by mounting a camera on a motorized Meade controller and taking a host every 5 minutes as the mount rotates for 90 minutes.
Here is how Hugo describes it:
"A 360+ degree panoramic time-lapse. The camera shot one picture every 5 seconds while the motorized mount slowly rotated. I then I assembled the images into this panoramic movie, in which each "pane" is actually the same movie, slightly offset in time" #
I've seen some crazy setups for high speed photography utilizing all sorts of weird parts. There is even a system that will turn the lights off for you, if you so please. But, this is the first time I am seeing such a huge overkill in term of components used to gain some control over the circuit.
Our buddy Destin from Smarter Every Day is about to have a new baby, but seconds before rushing to the hospital, he shares a neat slo-mo (or high-speed, depending on your take) video of a Canon 60D shutter going through the a full exposure cycle.
You can see the four stages of the exposure:
- The mirror flips
- The first curtain goes down to expose the sensor
- Second curtain covers the sensor to end the exposure
- And finally the mirror jumps back up
Now, here is a question for extra credit, can you calculate the exposure time?
If you are like me and like this kind of random science, you can register to Smarter Every Day Youtube channel here.

Eeeeveryboy loves Bullet Time. Bullet Time is that magical moment in a movie when everything freezes and the camera makes a circle or a semi circle around an object. I guess it is called bullet time cuz the camera moves at the speed of a bullet.
By now, you probably know that this effect is achieved with a battery of stills camera that will set you back a small house. To achieve Bullet Time, the photographers (or Bullet time specialist) places cameras in a circle and use both a green screen and clever triggering software.
The big number of cameras are used to maintain smooth motion as the point of view moves from one camera to another.
The Triggering mechanism is used to trigger the camera one after the other in very close succession, so it would seem like time is still flowing while the POV changes.
And the green screens is used to eliminate any interference and gain control over the set.
Or..... You could crowd source it all. Click to continue ›
On our last post we built and used a sound trigger to shoot a crossbow shoots an egg, today we add a photo gate trigger and shoot things falling.
After using the original trigger circuits for quite a while, I decided to make some improvements and to amalgamate the various devices into one, and to finally "hard wire" the whole lot. My excuse was that while I was incorporating the improvements I could rationalize the kit, but to be honest this was a bit of a vanity project. The finished control box is better, and much more versatile, and has enough knobs and switches to impress the unwary, but functionally the quick-and-easy separate circuits are just as good!
So, you can treat this post as a bit of a vanity project too, and skip it completely unless you are a inveterate tinkerer yourself! Click to continue ›
On our last post we saw what high speed triggers are available, on this post we will build our first trigger and and take the very first high speed photo.
I started doing high-speed photography after being wowed by images I saw on the Filckr. Images made by hobbyists like me. As a very experimental (purely for fun) activity, I wasn't about to commit large amounts of money to it. Click to continue ›
