Generally, if you treat your camera
filters, whether it is glass or plastics filters, the same way as you
treat your camera lens, then you should be alright.
Cleaning the camera filters
-
Make sure that you use lens-cleaning
tissue that is specially made for optical surfaces.
-
If you find that there are dirty
particles and dust on the surface of the camera filters, try to blow
away the particles and dust by using an air blower or commercial canned
air product expressly made for the purpose.
-
When working in an extremely dusty
climate, try to bring along in a tiny battery-powered micro-vacuum.
-
When using the camera filters in a high
humidity area, try to use special edge-sealed filters instead.
-
To check the condition of a lens or
filter surface, tilt it in various directions so reflections from the
surface don't obscure your examination.
-
Do not apply alcohol to the camera
filters! Do not apply the cleaning solution directly to the lens
surface; rather, place a small drop on the tissue and use the moistened
tissue to clean the glass surface. After applying the fluid to a ragged
edge of the tissue, clean in a gentle circular motion until there is no
visible trace of the cleaner, dirt, or grease.
-
Avoid using water to clean filters or
lenses as some filters are made by a laminating process and water can
cause dye spotting, swelling, and strains in the glass.
-
The key to effective cleaning lies in
maintaining a soft touch. Bear in mind that the cleaning fluid is a
mild solvent so it will do its job with little physical effort from
you.
Storing the camera filters
-
If a filter is to remain on the lens, use
a lens cap.
-
If not, return it to its storage box or
pouch immediately after it is removed.
