Hello. I was wondering if 18% car tint would be the same as using a
welders mask to use with my camera. I was thinking about putting it
on my sun roof and having my camera under it. Do you think that
would protect my camera from being damaged? Any suggestions would be
appreciated.

Thank you
Not a chance. 18% transmission vs recommended less than 1%
2 #9 welding filters stacked gets close - I can JUST see the LED
light
on my blackberry through them. A 9 and a 10 together are dark enough
to be safe.Not sure how much you will see through them.

The #5 + #10 I have makes the sun appear about as bright as the full
moon.

I checked both 5+9 and 5+10, both are totally inadequate. A 9+10 looks
pretty good.

BTW auto-darkening helmets won't stay dark without the flicker of an
arc. I check if my Jackman is on by aiming it toward the sun and
waving my glove in front of it. It only darkens momentarily.
