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.
Set up the lighting
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 Peekaboo mode on Triggertrap Mobile
Once everything is set up, it’s time to set up the triggering. First open up the Peekaboo mode on the app. When you open the mode, you can set the number of faces using the dial next to the big red button.
Set up Triggertrap Mobile
Now the app is all set up, you need to plug everything in. Connect your camera connection cable to your camera, then to the Triggertrap Mobile Dongle. Finally plug the Dongle into the headphone socket of your smart device. You may want to test everything is connected properly; the easiest way to do this is by going into the Simple Cable Release mode and tapping the button. If the camera fires, everything is set up perfectly! Be sure to switch back to Peekaboo once you have tested that it’s connected.
It’s crucial that the device is pointing at your background so that the camera in the device can easily spot the faces of your subjects. The X-Grip from Tripod Clamps is absolutely perfect for this. Simply clamp the X-Grip onto the tripod then drop your device into it’s grip. Make sure the camera on the device is aimed at roughly eye level to your background to ensure it can see the faces. Alternatively, the Triggertrap Phonetrap is perfect for holding the iOS device on to your hotshoe.
