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 |

Ok I was just trying to figure out a way to take pics without killing my camera.
I did just pick up a UV filter lens for it. Would that help? I just don't want to take chances. Thank you |

Thank you Jon.
I did find a multi coated UV Filter for my camera. I also have the glasses. I am going to do some more research on it to see if there is anything else I can do. If you come up with any ideas, please let me know. I'm not taking any chances with my eyes or my equipment. Have a great day. Misty |

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.

It only darkens momentarily. -jsw |

Walk around wearing a welding helmet and propellor beanie and tell people they protect you against dangerous rays from outer space. |

Have a great day. Misty Turn on your damn TV. Or login to any number of websites. You'll find eclipse pictures better than you can take. And you won't blow out your eyes setting up your camera. I can't understand why people who are concerned about damaging their camera are willing to risk their eyesight on possibly the most risky situation they'll ever encounter. Are two minutes of, "ok that's dark" worth risking a lifetime of, "everything's dark?" Stay home and turn on your TV. I don't have a TV and the photos I take will have MY copyright on them with no restrictions on how I use them. This shows the unfortunate part of the pervasiveness of the net. Such over-wrought posts get distributed wildly. During the last total eclipse - 1978 or thereabouts - there was none of this kind of hysteria. The instructions were simple: Don't look directly at the sun without protection. Don't rely on sun glasses. Welding filters or fully exposed B&W film are adequately dense. Don't look at the sun with any magnification regardless of the presence of outlet filters. No mass casualties afterward. Misty: Your UV filter will do nothing to attenuate the brightness of the sun in the visible spectrum. It's probably too late now to get them but welding filters are wonderful. I fabricated a bracket to hold a stack of them in front of my camera lens. I use a stack of filters, both to fine-tune the density and to still have protection if one failed. With the old glass filters, there was a risk of cracking from the heat. Most (all?) filters are now made of plastic which won't crack. If the front one were to start melting, I would notice that as the image on my camera start to brighten. I have tested my setup extensively with the clear-sky sun and it works perfectly. If you have a point and shoot camera, a filter out of the cheap viewing glasses (ISO, UL and ANSI approval vital to separate out the fakes) can be held in front of your lens. My viewing glasses are a little dark for good photography but if you put your camera on a tripod so you can use a slow shutter speed, it should work well enough.

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).

I know my pictures will not be the best because I didn't spend a zillion bucks on the setup. The important thing is that I own the shot and can therefore do anything I want with them. Including publishing them on my website with a Creative Commons mark so anyone can use them. OK just how is joe sixpack gonna tell if his glasses are approved? Well, the ones I bought have all the approval stamps printed on the insides of the earpieces. And they came from a reputable source. Do you weld? If so, how do you know that your welding filters are authentic? After all, a stick-welding arc is as bright as the sun and you DO stare at that light source for long periods of time. At some point, you just gotta trust the approvals listed on quality name-brand parts.

The test to see if the solar glasses work is a very easy test. 1) Look at the sun -- you should see it and be comfortable 2) Look at other bright objects, such as a clear incandescent light bulb, you should at worst barely see the burning filament. |
