What are similar photos?

Generally, similar photos are photos that have a relatively high degree of visual similarity. They are similar but different.

There are various kinds of similar images.

• Visually identical photos different in resolutions or file sizes
• Visually identical photos in different formats, for example, one in HEIC and the other in JPG
• Photos taken in burst mode, which look alike
• Visually similar pictures of the same subject captured from slightly different angles, distances or exposures
• Certain edited (e.g. rotated, cropped or watermarked) versions of the same photo
• Other visually alike images
