Q: Low Ambient Lighting Help...

like previous post, bounce the flash.. and if you don't have a ceiling or its very high.. lay a white sheet across the top of the cage, will help keep the light you want in the cage and help to keep the natural colors of the animal cause if you bounce your flash and the wall is brown or red.. you will get that big of color in your animal.

Yes bounce it or shoot with it with a slower shutter speed. Ambient light but using the flash as fill. I use this for outside wedding shots.
