A collage is a group of separate images that are positioned together artistically into a single image. The images may be cropped first before positioning. Images can be blended into the background so that the final image shows seamless combination of photos. Images can also be "cut out" from their original background and placed in an attractive composition onto a graphical background.

Images can benefit from enhancements to improve the overall image quality. Examples of parts of an image than be improved include: See Image Adjustments for more information.

The choice of cropping for an image can dramatically alter the impact of an image. Examples of ways to crop include: Remove portions of the background that don't contribute Emphasize the main subject which is small in the overall image Position main subject within the overall image for more a more dramatic look Achieve a specific ratio of width to height so that prints can be positioned properly within an album or frame.
