I have poison dart frogs that I love to take pictures of and post to
dart frog boards and my web site. The camera I use is a Canon PowerShot
A95 with a ring adapter and a set of macro lenses (1X, 2X, 4X, and
10X). I use a tripod to take the shots when possible, but I have a
problem with glare, either from a bounced flash or from the fluorescent
lights on their tanks. You can see what I'm talking about with the
following pic. 56K warning on the pic:

I did not use a flash for this one, as you can tell by the shadows, but
there's glare on the frog's back and legs from the light on the tank. I
can't exactly take the frogs out and stick them in an environment
that's more suitable for photography. Are there any settings or filters
I should look into to get rid of the white spots?

I guess they are just annoyed with you.
Can you try and lighten their mood up first before taking the pictures?

Perhaps a polarizing filter? If not, consult a TV makeup
technician to find out what they apply to news anchors to reduce
glare from their faces. The frogs may not appreciate it, but it's
probably less fatal than painting the backs of turtles. :)

Also, maybe you could eliminate the tank's light and either use a
diffuse light source or move the tank outdoors or near a bright
window?

That's a polarizing job. Depending on the situation you may get by with
just one on the camera or you may need to polarize the light as well.

You may place a diffuser in front of the illumination of your tank. That
should give you softer light. Or use a flash unit connected via a butterfly
bracket to your camera. For instructions on how to make such a bracket see

It is obvious that your camera lost all image information in the highlights.

I don't know if this will help (and I have no personal experience with
this product), but I have seen a filter being offered as a "ultra
contrast" filter that the description seems to fit your situation. I
recognize that if you are taking these photos in a location not under your
control (such as in a zoo display) and so making changes to lighting is
not likely. You may even have to layer filters to get rid of all the
various problems. A polarizing filter to get rid of glass reflections, and
a contrast filter to even out the contrast to reduce reflected highlights
from your subject.

One other suggestion, if you can press the front element of your lens
against the glass (and possibly use a cloth sleeve to cut out reflected
light) and then placing a flash at a distance to the side also pressed
tight against the glass. This way you can get the light bright enough on
the subject that you can close down the aperture enough to reduce blown
highlights.
