Two Different Image
How To
If you don't see a video image, you need to allow the browser to ask for permission to use the camera. That is in the browser settings. Then when you are asked if this page is allowed to use the camera, you need to allow it.
To make a Two Different image, tap (or click) on the video image to “snap” it. Move the camera. Then when the watch icon disappears, tap/click on "Open snap" to view the image you just snapped. In that area, you can make some adjustments to the image, to change the colors or contrast. You can save or share the image by pressing and holding on it (or by control or right clicking on it).
If you choose the "Standard" technique, then the image will be a classic double exposure. If you choose the "Different" technique, then the image will be ... different.
