High Speed Photography - Let Arduino turn The Lights Off For You
If you're reading DIYP for a while you probably know that High Speed Photography is not about high shutter speeds. Au contraire. It is about shooting very long exposures in bulb mode, and using a strobe to freeze the action with a split second light.
This means that once you have a setup read to go, you turn off the lights. go back to your setup and pop the balloon / break the glass / shoot the bullet. Kinda messy and uncomfortable. Ask Edward Horsford, the exploding balloons magician.
Photographer Matt Richardson came up with a better to do it. Matt was already Using an Arduino as the triggering device for the strobe. It only made sense to Let the Arduino turn off the lights and open the camera shutter once the setup was ready.
In the video after the jump, Matt explains this concept, and shared the circuit to make this magic happen.
This is the circuit to get the camera and room lights hooked up into the Arduino board.
Lastly, the source code for the project can be found here.

Really cool, but I would make
Really cool, but I would make one change. Add a delay in from button press to "lights out" so that you can be all setup/possed before the lights go out.
thats terrific tip
You are one hell of a powerhouse Edward! Superb setup and whatta cool idea implimented so well and so easily! really nice man! Thankyou soo much for sharing this!
Need more info
I saw the breadboard diagram, ut i Need more information about optorelay (Part nuber and etc)/ And You don`t describe the element of powerswitch....
I think that all need more links about it. Like these... http://www.glacialwanderer.com/hobbyrobotics/?p=9
Wery simple and intresting project... You are like magician... It`s soo simple... but give us full datashit of details not photo of breadboard. I am loking many time the videofilm but don`t understand the type of optical triger. Help me and my eyes.
Mat it be RELAY, PHOTOVOLTAIC; Voltage, Load RMS Max:300V ac; Voltage, Load RMS Min:0V ac; Base Number:3054; Case Style:DIL-8; Current, Control DC Nom:5mA; Current, Load:40mA; Current, Load AC Max:40mA; Current, Load DC Max:40mA; Logic Function ...
That was my idea! Just
That was my idea!
Just kidding! I already build a prototype of long exposure timer using an arduino with LCD feedback.
on my to-do list there is a menu to the system, time laps trigger, and high speed photo trigger to add.
Mabe one day when I finish the thing I'll try to document it and release it if people are interested.
tutorial?
Is there a tutorial on how to make this arduino sound flash trigger please?
DIYphotography.net should be all about diy and i can't seem to find a decent tutorial on how to do this for us non electrical minded people.
showing a board diagram is not even helpful - you might as well post instructions in latin :o(
thanks
Patrick
re: tutorial?
Hi patrick,
Thanks for highlighting the point that not everyone has the same level at electronics. There are some great and very details Arduino projects that can help you slip in easily over at Make.
As much As I;d love to cover everything, the span and focus of DIYP simply wont allow it. If you dont have good arduino know-how than there are bought alternatives like CameraAxe and Photodrino, which so a lot o the work for you.
Might be interesting here...
Perhaps Photoduino might be interesting here...
Dear comrad , you can find
Dear comrad , you can find more information for non elctrician man here http://www.glacialwanderer.com/hobbyrobotics/?p=11
"'Triggering a Camera’s Flash with Sound and Light'' , the issue is more helpfull for understanding.
These sheme is intresting too.... Looks great ! But we need a list of partnumbers....
Arduino is very simple the most hard thing is the sheme of components and the program for the microcontrolers
Audio triggers for Flash
Very cool video. Been thinking of doing some high speed shots and this gives me some food for thought. I used to visit Edger's lab in MIT 35 years ago...
1> Is there any reasonably priced trigger that comes preassembled in a stable package?
2> I need something where I can reliably set the trigger volume and delay...
3> Why did your setup need software?
Thanks.
Arduino camer controller (photoduino)
Photoduino is an open source camera controller based on the Arduino platform. Its main purpose is to serve as technical support for taking photographs of various techniques such as: Timelapses, High Speed Photography, Photography of insects and animals, storms Photography or HDR Photography among others.
