The iris is the coloured part of the eye and it is (pretty) not affected by the red eyes problem. The red eye is a reflection of the light passing through the pupil and reaching the retina. The retina has many capillary vessels and what is red is the blood in these capilaries under a strong direct light. ____________________________________________________________________________ > darktable user mailing list to unsubscribe send a mail to > [email protected] > ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
