Default eclipse. car tint vs welders mask

Thank you Jon.


I did find a multi coated UV Filter for my camera. I also have the
glasses.


A UV filter won't do much for what comes through the atmosphere
from the sun. The (eclipse) glasses will.

I am going to do some more research on it to see if there is anything
else I can do.


What kind of camera and lens? If just a small digital camera
with a lens no bigger than the maximum circle you can superimpose over
a single eclipse glasses lens, just hold it in front.

If a larger zoom lens, make an opaque sheet (aluminum would. be
nice), with a hole to match the eclipse glasses lens, and large enough
to cover the full diameter of the camera lens. Paint the aluminum side
towards the camera lens with a flat black pain.

If you have a mirror telephoto, do the same but make the hole
off-center so it is over part of the clear area of the front element of
the lens. A central hole will be blocked by the mirror mount. This
will let through less light than you would want for your camera if it
were the same sensitivity as your eyes, but most digital cameras can
automatically switch to much greater sensitivity than the daytime
sensitivity of your eyes.

A true digital SLR camera will only expose the sensor for the
very short time the shutter is open. The kind of digital camera which
uses the display as a viewfinder has the sensor exposed almost full
time, and it is more likely to be damaged if the light is not
sufficiently reduced.

If you come up with any ideas, please let me know. I'm not taking any
chances with my eyes or my equipment.


If you're thinking of using a UV filter for either the camera or
your eyes, you *are* taking chances with them.

None of this is certain, as I don't know your camera (nor your
eyes, actually).

Have a great day.
Misty


Good Luck,
DoN.
