Live View Overlay
|Top Previous Next|
Photo Booth Mode
An optional overlay image can be displayed over the live view images in full screen photo booth mode to add fun effects such as superimposing a body builder's body with the user's head. It can also be used to create fancy borders for the live view images to give the booth a more custom feel. It can also be used to provide alignment guides if the photo booth is being used to take passport or id photos.
The overlay image should be a PNG file with transparency information in the alpha channel and saved in the photo booth images folder.
Stills Photo Booth Mode Live View Overlay
In stills photo booth mode the overlay should be named live_view_overlay.png and have an aspect ratio of 3:2 e.g. 960x640 pixels in size. If the aspect ratio of the overlay image isn't the same as the live view images it will be stretched to fit and may appear distorted.
The live view size for most recent Canon cameras is 960x640 pixels when in photo mode.
Video Booth Mode Live View Overlay
In video photo booth mode the overlay should be named video_live_view_overlay.png and have an aspect ratio that matches the currently selected video resolution. This is normally 16:9.
If boomerang GIFs using the camera's photo mode are selected the live view will have an aspect ratio of 3:2.
Ideally the live view overlay should be the same size as the live view images (typically 960x640 pixels in photo mode or 1024x576 pixels in video mode). If the aspect ratio of the overlay image isn't the same as the live view images it will be stretched to fit and may appear distorted.
Please note: The live view overlay image only affects the live view images displayed to the user and won't appear in the printed output or the video. To overlay the images in the printed output create a copy of the live_view_overlay.png file called image_overlay.png and save it in the photo booth images folder.
Overlays can also be used in conjunction with green screen shooting to provide effects such as foregrounds or overlays to mock up a magazine cover.
