    Getting into long exposure photography is really fun, but also pretty costly when buying some 10 stop filters from brands such as Hoya ,Cokin, B&W and Lee, etc.

    Me along with a friend of mine decided to venture into this when he heard of a solution using welding helmet glass. So we started doing some research.

    Welding glass come in many shades. Shades are pretty close to "stops" so using a shade 10 is like using a 10 stop filter from the famous brands.

    The catch to using welding glass is it is tinted green in most cases, so doing anything but b&w long exposures you will get a green cast on the entire image, which is removable by messing with the white balance, i have not personally done this as I shoot b/w 95% the time.

    I bought my glass from ebay for 5 dollars in a 4x5 inch shape, dimensions vary from company to company. I hotglued a old 52mm lens hood to the glass so all i need is to use a stepup ring for whatever lens I have to 52mm thread, in this case a 37mm-52 and a 40.5-52. You can hotglue it to a step up ring if you like it does not matter much. the entire setup cost me 10 dollars, and the photos come plenty sharp through the glass, of course theirs a learning curve but its pretty small.

    I use this setup on my om-d not the e-pl1 as pictured.

    A nice, creative solution. Do you get the same effect on B&W that you would using a green filter? Î wonder what that would do to landscapes as opposed to water?

    Thanks Bob! The green cast goes away immediately when converting to black and white, i dont think it affected tone either.

    Interesting! I only mentioned the green effect because programs such as NIK allow you to use various color filters to alter B&W. Of course, these allow you to remove a certain color such as green or red or blue - I wasn't sure what effect adding color might have.
    You also reminded me that I have a set of rectangular Cokin style filter that I need to try with my E-P3. :cool:

    Gotcha, much like the red filters and yellows etc from the film days. I havent noticed a change in tone but it will be interesting to see if it really does, i'll take note of it!

    You can actually buy welding glass that is (I think) already the correct size to fit in a Cokin style plastic holder - you can get Cokin holders (well knock off copies) on ebay for a few pounds/dollars and the welding glass also on ebay or on amazon for £2 delivered. As you can see from the customer reviews quite a few people have been using them for this non originally intended purpose :smile:

    When someone posted this idea on a UK photo forum complete with an ebay link to the £1 glass, the seller went from a couple of orders a week to hundreds in a few days. He wondered what on earth was going on and why welding had suddenly become so popular until he asked one of the buyers and they gave him a link to the forum, which solved the mystery. :biggrin:

    So is this the same thing?

    Though it occurs to me that I have an unopened b&w 10 stop ND filter so I don't need to DIY lol.
