During a discussion about red-eye a while back, someone posted they
experienced "yellow-eye" in photographs of humans ("yellow-eye" is the
common risk in canine photographs). As I had never seen it before in
photographs of humans, I kept wondering what caused it.
In researching the structure of the eye for writing a tutorial about
reducing red-eye risk I looked at a cross-section of the eye. The diagram
shows a "yellow spot" above the retina at the back of the eye. I'm
suspecting the human "yellow-eye" is a reflection from this spot at the
back of the eye. This would be similar to what produces "red-eye" which is
a reflection from the blood in high concentration of capillaries in the
nearby retina.
Anyone steeped in knowledge about the human eye want to comment on
this? Is this the source of it?
