Montgomery County Animal Shelter is in need of
photographers to volunteer their time on Sundays
to photograph rescue dogs. Volunteers at the
shelter try to take better pictures of the animals
than their original intake picture so it can be
posted on the shelters Facebook page to hopefully
to help get them adopted. The shelter has over 64k
followers who see these pictures and have come to
love seeing the animals dressed up.

interested in volunteering their time on Sunday’s

take pictures at the shelter and they can’t always
be there so they are looking for more volunteers

The Science of
Lens Filters – To Use of Not to
by Andy Howard ---
are several questions that will divide the
opinions of photographers. One I have seen
recently is “Should I use a filter on my lens?”
The question isn’t about “special effects” filters
like star, polarizing, neutral density, etc.
Attach them to the lens as you need them. No, the
question with diverse opinions is “Should I use a
UV filter on my lens?
quick, “scientific” answer is “no”. That is, in
the days of film, photographers used
“ultra-violet” blocking filters to protect the
film, which was extremely sensitive to UV light.
Digital camera sensors are not sensitive to UV
light, so you don’t need the filters for that
reason. Further discussion involves personal
preference, with a few things to be aware of.
a filter to protect the lens glass from scratches,
smudges, sand, spray, fingerprints, etc. Filters
are easier to clean than lens glass. The more
glass you put in front of the lens, the more
chances for reflections, flare, and reduced
sharpness. If you do use a filter, pay the money
for a good-quality one. If you have a large size
lens mount (e.g., 67 mm), be prepared to pay a
“large size” of money.
a filter to protect it from hits – a filter is
cheaper/easier to replace than lens glass. But
remember, a filter is a filter, not a lens
protector; it is not designed to be impact
resistant or super strong. If a hit is hard enough
to damage a filter, most likely the lens will be
damaged as well. (Personal story to the contrary:
I dropped a camera with the end of the lens
hitting first. The lens cap was jammed into the
filter, which was dented and the filter glass
shattered. A pair of pliers [figuring the lens was
toast anyway] extricated the cap and unscrewed the
filter frame. The lens itself was fine but I would
not recommend routinely making this test!).
screw mount for filters extends further out than
the lens and will help avoid bumps. Sure, there
are lenses where the front glass is curved out but
filters aren’t made for them anyway. A lens hood
can help protect the lens but can also “attract”
bumps due to the length of the camera/lens/hood
summary, while a digital camera sensor is not
sensitive to UV light and a UV lens filter is not
needed, it is the photographer’s preference to
decide whether to use a filter or not. Have fun
shooting in the new year!
