Definition
A photomosaic is an image composed of many smaller photographs or tiles, arranged to create a larger, recognizable image. Think of it as a picture made up of lots of tiny pictures. Each small photograph contributes to the overall appearance of the larger image. Unlike a regular photo, a photomosaic reveals a new level of detail when viewed up close. They're often used for artistic purposes or to commemorate special events. The individual images are chosen based on their color and tone to contribute to the final composite.
