A Photo Mosaic is made up of many images. These are laid down in a grid and work together with the main picture to produce a Photomosaic.
To create a photo mosaic you need one Main image and at least 200 individual photos. The more photos you have, the more detailed your mosaic will be. Best result when the number of photos is between 600 and 1000.
For the best results, use a close-up as the main picture. With a close-up or a zoomed image, the subject or the persons are as much in focus as possible for the best result possible.
