Note: For best results, photos must be frontal, like a passport picture and visually cleared - without any glasses, sunglasses, hands or locks of hair on the face!

Note: The quality of the photos will affect the results. When comparing same photos from different devices, there can be a difference of 2 to 6%.

Note: Use as recent photos as possible to get accurate results. As people change over the years, their psychological facial features change as well. It is not uncommon to get different results when comparing photos of the same person at different ages.
