Redeye is caused by larger apertures and not by relative
darkness, causing the pupil to dilatate?

I've only seen redeye in dark circumstances at 10+ meter
distance using my 550EX (in direct forward flash
configuration) --- and the photographer is much closer than
that.

As for the slightly diffuse light ... how much larger
is the diffusor over the flash's front lens?

Red eye is caused by the flash going directly to the eyes and back to
the lens. It is made worse when the pupils are larger, due to low
light.

When I photograph cats, the color of the eyes is very important. I
usually shoot inside an enclosed canopy, so low lighting is
guaranteed. I set up continuous lighting with the specific purpose of
keeping the canopy bright enough that the pupils will stay contracted,
allowing the natural color to really stand out. I use umbrellas to
keep the light soft enough that the cats do not squint (too bright is
worse than not bright enough). And then I bounce the flash to get a
well lit photo without any red eye.

That is funny!

Now I need to do one like that intentionally.
