just like to ask: how to shoot zoo animals (or anything) through glass ?
some websites seem to suggest shooing with the lens at 90 degrees to glass while others say that the lens should be placed at 45 degrees to glass surface....
then also read that circular polariser can cut reflections...
1. circular polariser must be placed at 45 degrees to glass surface for it to work, is that true? was told that if polariser placed perpendicular to glass surface, then NOT effective....
2. is it good practice to placed lens 90 degrees to glass surface and shoot through the glass? (tried that with hood on glass surface... found that can shoot flash without the reflections getting into the camera.... compared to activating the flash at 45 degrees, camera will capture the reflection of the flash on the glass)
3. which is the best way? are there any other ways?
