The first step is to set up your backdrop. Remember to try and give yourself a fair bit of distance between the camera and the background. If you aim to give yourself between 12-18ft you’ll have plenty of room to get your subjects away from the background.
Once your background is set, use some gaffer tape to mark a spot a few feet from the background to show people where to stand. This is particularly helpful for keeping things in focus! Proper gaffer tape is always your best bet for this.
Set up the camera
Set your camera securely on the tripod and then extend the legs so that the camera is roughly at eye level. You might need to think a little about what focal length to use on your camera, there’s a great resource here showing how focal length changes the appearance of people’s faces.
Set the camera on manual exposure with a reasonably large aperture (f/8-f/11) to ensure a good depth of field.
Next, set the camera to manual focus. Try and get someone to stand on your marked spot so you can set your focus accurately, otherwise, tilt the camera down and focus on the tape you’ve marked the spot with.
How you light the photo booth is really down to you. To keep it really simple, if you have a white ceiling, make the most of it! Put the flash on the camera and aim it up at about 45 degrees. The light from the flash will hit the ceiling and bounce back, lighting your subjects in a much nicer way than pointing the flash directly at them would achieve.
If you want to take this further and set up off-camera lighting, there are loads of options available. David Hobby at Strobist has created an amazing resource for learning off camera lighting, be sure to check out Strobist 101 here.
Set up the sound sensor
Connect Triggertrap Mobile to your camera and mount it securely to your tripod. Open the Triggertrap app and enter Sound sensor.
Adjust the threshold to be quite high (we want people to shout!) and above the ambient noise of the room. If you are using an Android device, you might also want to turn the sensitivity down. Press the red button so that your device is listening for sound, and you should be ready to go!
If you find that the microphone is still too sensitive, try taping a piece of gaffer tape over the microphone.
