Glass

A question for the more experienced,
How do I go about shooting through glass windows? as my local zoo has alot of reptiles etc behind glass.
Any help please..
Thanks

Install a cheap rubber screw on lens hood and press it right against the glass. The closer you can get the glass to the lens (without touching the lens glass) the better of you will be. This will help eliminate any glare and also keep the window in a range where it will likely be out of focus and therefore show less detail/dirt in the image.

I have had good luck with a rolled up piece of black construction paper. It does the same thing. Roll it into a tube just a bit longer than the lens. The paper sits against the glass shielding all the reflections.

If you can't get to the glass to block reflections, you can use a polarizer.

Another trick is to bring a friend in a black/very dark shirt. You can position the friend so that the only reflection is the dark shirt. This is usually much less apparent than any form of bright or light-colored reflection.
