to Photograph Birds in an Acrylic Aviary (cont)
shooting through Plexiglas
are a few problems you will encounter when trying to shoot through
Plexiglas tends to produce glare or reflections that can corrupt
your photograph. Making sure there is less light outside the aviary
than inside the aviary will help reduce this effect, but will
probably make your lighting conditions worse. If your camera has
a threaded lens, you may be able to buy a compatible polarizing
filter. Polarizing filters reduce reflections in such surfaces
as glass and water. However, they also filter out some of the
light; again, making any existing problems with underexposure
even worse. For this reason, I do not use my polarizing filter
when photographing my birds.
deal with reflections and glare, when possible, I do the following:
off any unnecessary lights that reflect strongly in the area
I am shooting, pull curtains far enough to dim the reflection
in the area where I am shooting.
off my flash if I don't absolutely need it.
to shoot in a location with little-to-no glare.
the door and shoot through the open doorway or stick my head
inside and shoot from within the aviary.
shooting through Plexiglas can affect the quality of the images.
To reduce the effect as much as possible, I keep the Plexiglas
clean of dust, debris, fingerprints, and droppings. If there is
something on the glass at the time of the shooting, I avoid that
location when setting up. Using a narrow depth of field can also
throw any obstructing blemishes far enough out of focus to not
be visible. When cleaning the Plexiglas, I use a soft cloth. Using
paper towels or other paper products will scratch the Plexiglas
over time, making it difficult to shoot through. Also, make sure
you clean the Plexiglas with cleaners that are safe for the material.
Ammonia-based cleaners can cause the Plexiglas to cloud over time.
I use simple vinegar and water.
