Photo guidelines eyes

Lighting conditions

The image shows a shaded and a well-lit image.

The image should not be too dark so that all details can be seen.

Quality

One image is pixelated and the other is of good quality.

Please do not upload pixelated images. Photos taken with a smartphone are perfectly sufficient.

distance

Image of a person who is far away and image of a person up close.

The person should not be too far away. Zooming in is not always effective with moderately high-quality images, as the quality decreases with zoom.
