Choose an image from the Camera Roll/Gallery and it automatically gets overlaid on top of the first picture. The app will confirm the tool selection and now you should tap on the image+ icon at the bottom-left.
The icon depicts two overlapping circles and its also at the bottom of the menu. Launch the app, hit the large plus-button, and choose an image from your Gallery/Camera Roll. Here is a quick guide that can help you avoid trial and error. It might take some practice before you nail just the right look. The final result you get with this tool is similar to the dreamy analog photography double exposures. Not only that but there’s a hack to make a collage. This allows you to create artsy images that are bound to attract likes. To be exact, the 2017 update introduced the Double Exposure tool which lets you merge two images. There is still no option to create a collage, but the app allows for some combining of images. However, Snapseed has long missed the feature to combine photos or put them in a collage. Snapseed is a true powerhouse of a photo editing app, and the tools it offers can only be rivaled by Lightroom (the mobile app).
