$1.98 ND filter...made from welding glass
Last year Vitaliy P and This charming broad began to post a series of awesome daytime long exposures. Even cooler, instead of buying an ND filter, they rolled their own using welding glass! You can check out the photos they've taken with it here and here.
So when I wanted to take some daytime long exposures with my Rolleicord the other week, I went to Lowes and picked up a piece of welding glass for $1.98 USD (link).
This was shade 10 welding glass, which is supposed to be the equivalent of about 12 stops, but the photos I took came out underexposed so I'm guessing the one I have is more like 13 - 15 stops. A good excuse to take more photos and find out... I'm glad this one came out underexposed though.
I have a couple of pictures of my Rolleicord / welding glass rig in the comments below.
UPDATE: The underexposure was due to me not accounting for reciprocity failure, not the welding glass shade # being inaccurate.
