http://photo.net/equipment/filters/Interesting are the comments regarding name brand and off brand filters looking like the same transmission curves. But back to the case at hand, protecting the camera sensor. If you add one, UV is about 50% cut below 375nm.. curve drops quickly to lesser transmission. Lets say you put two filters on, little visual blocking will occur, however below 375nm 50% of 50% will be transmitted or 25% and as the shift is more toward UV (lower nm #) the transmission will be cut off drastically... of course it depends on the filter... the article mentions greater UV adsorption with warming filters. Give it a read.. Science is not a thing of opinion rather of fact... given a choice... go with the facts...

That's just your opinion! I'm joking of course. I really don't think I'll have a problem with the sensor. The process of welding is very hard on exposed skin as well as the eyes. :thumbup:
Yes, I realize that, I have never been concerned, have taken photos of sun coming up over ocean, lots of UV. I have a IR convert and took photos of molten glass and the ovens, with and with out IR filters, ... the sensors are tough little things... But if a person is concerned... better to give them "protection" so they will not fear their sensor getting aids better safe than sorry.. one thing to zap a $50 camera but a $2000 camera that is where I would be really really careful.

I always practice safe shooting and put a condom over my lenses in place of a UV filter. :thumbup: Photos are not as clear however. I'm glad to see another UHH'er with a sense of humor. I've really pissed off a few people lately with my "warped" sense of humor. :roll: :lol:
Try an autodarkening hood for your cam
Good luck & post your pix

I like the auto hood idea. I was once a welder and when between sticks I had the hood up when working in the same room with another welder, I burned my eyes as did he. The next day both of us has sand in our eyes. Be careful around welding.
Pounder35, all humor that is not cruel is warped-ironic or a surprised connection. Example your saying at the bottom of your contributions: IN WINE THERE IS WISDOM, IN BEER THERE IS FREEDOM, IN WATER THERE IS BACTERIA! This is true and it the original reason for beer and wine is bacteria in water... the humor is that it points out that water is commonalty polluted with bacteria and virus that the action of fermentation kills. Worse case you die happier. The fact that water is contaminated when it is usually thought of as pure is the ironic-humor.
I was a rather pure young man before moving to the big city, filled with wild sinful opportunities. I resisted as many as long as I could; to live a balanced life I engaged in as many as possible. My humor,for mental survival, became warped when working medical research cutting up human and animal tissue for trace metal analysis.
Back on Track of Forum: In a situation like the protection of lenses/sensors analytical analysis needs to be applied. In this case we have vapors/particulate stray missiles of molten or hot metal flying quite a distance, and of course the UV. IR however, may be the greater threat if too close. But in the final essence all I would use in a similar situation is a UV filter like I always use to protect my Lenses.

I plan on shooting from enough distance to keep molten metal off the camera. And myself. :lol: I was at the school today doing a little welding but didn't take my cameras. I've got the shots set up in my mind and will probably work on the project this week. I will cover all the technical classes as well as the nursing school and computer science lab. The welding was my only concern as far as taking care of the camera. Of course in the brick masonry class there could be a problem with falling objects. :roll: :lol:

You should also watch out for falling photographers.

That would be me. Amazing what you can fall over with your eye glued to the eyepiece looking for that certain angle and light. Been there. Always twist and save the lens. :thumbup:
Keep an eye on eyes. You can walk on a wooden leg, chew with false teeth, but
you don't see much with a glass eye.

There sure are a lot people walking around with two glass eyes. And driving. :roll: :lol: :thumbup:
