The red eye is caused by the angle off the lens axis of the
flash. At 1 meter the shoe mount flash is maybe 15 degrees
off the axis, at 8 meters it is only one ot two degrees off
axis. Very much the same as using the RTF at closer
distances. In fact at longe distances you can even get red

Those sound like especially good mushrooms where did you say you found them?

Hi,
Human blood is red. Tending towards scarlet when it has oxygen
attached, tending towards crimson when deoxygenated. It is this
redness of the general tissue which gives red eye.
The reason most cats (try photographing Siameses) give green eye
is that they have an additional layer (the tape

Hi Gera
That would seem to be correct. My white calico, blue-eyed cat can get a
wicked case of red-eye.

Red in the case of Siamese cats (and, I suspect, other blue-eyed cats)

Hi Bob ...
I'm glad that you're not my doctor!
Your post is partially correct. Our blood is red. The blood that
flows in the veins id a darker red because the oxygen in the cells
has been exhausted, i.e., it's used blood. The blood in arteries is
a bright red, as it's freshly oxygenated.

Hi,
I'm no doctor (trust me), but isn't it the case that mammalian blood is
not red but blue when it's in the veins? It only turns red when it
oxidises (eg when it comes out of your veins). This would suggest that
red-eye is not a reflection off blood vessels, but off the retina
itself, which is

Which leads me to the question; do cats eyes have green blood vessels?

Ayash,
You understand that red-eye because you show the illumination of the red
blood vessels at the rear of the eyeball in your photo. You can do this at
any distance if your flash and lens are close enough. It is actually easier
to get/have red-eye with long lenses because the effective an
