View Full Version : avoiding red eye when photographing owls

Anyone using fill flash on large owls and *not* getting red-eye? I've
found the early AM pet roosting spot for a Great Horned Owl and two of
its large chicks but it's almost directly back-lit from the only spot I
can shoot from, so I need fill flash. I can get them full frame with
700 mm (equiv to about 900 mm with the digital body I'm using) so
probably about 20 yards distance.

The problem is that I get red-eye when they're lQQking my direction and
they're not very interesting when looking to the side. I'm using a
Canon 550EX flash off-camera at - 1.67 stops with a Better Beamer
extender on a 500 mm lens and have the flash mounted several inches
above the lens with a Wimberley flash bracket. I've never had a
problem with red eye in birds before with this setup but with these
larger birds with huge eyes at this distance it's a problem.

I also tried removing the flash from the bracket and holding it to one
side about 2 ft from the body (about as far as the cord will stretch)
but still get some red-eye, so I was wondering how people avoid it. I
have a wireless flash controller (ST-E2) so I could move the flash even
further and still fire it in E-TTL mode but it's a hassle to do this.

I know how to 'fix' red-eye in Photoshop but I prefer to get it right
in the camera, partly because I may need to send in the RAW file at
some point and partly because I just prefer getting it right in-camera.

Anyone know how far off-camera the flash needs to be for this type
situation? I can post a few sample shots if anyone wants to see the
problem.

any way you can get the flash about 1 foot off/above the camera? if you
can move the flash higher that the lens it should eliminate the redeye
your getting. (or green eye in most animals)

Regarding the red eye problem, angle off axis is pretty much
the only solution. The red eye problem is a reflection off
the back of the eyeball. When the angle is large, that reflection
does not make it out of the eye, hitting the inside of the eye.
A pre-flash helps a little on humans; I don't know about owls.

I've seen a lot of "white eye" with flash on birds. I've never seen
red eye, but then I've never used a flash on an owl.
