Default Re: Welding Glass (1/$1 ND Filter) Exposures

Coffee Filter worked pretty well for me. As I mentioned earlier I will be testing it with my Expodisc as soon as I get my ring and my cutter.

Thinking about whether or not it'd work to stack a circular polarizer with the welding glass. I'd think that it'd increase the stops needed for the exposure, but also cut down on flares and help make the skies bluer.

Got my ring yesterday. I have it glued to the welding glass. I'm just waiting on my cutting tool to arrive.

adding more glass will increase flares since light gets reflected again between the lens and the cpl.

I'm seeing quite a bit of pink cast in your shot. Did you shield the welding filter from the sun?

looks like that one and yes it is a wheel attachment.
Hey, do you have any recent examples with this mod? I'd love to see how yours turned out. Looking quickly at your flickr page, I don't see anything recent that are welding glass shots.

you probably won't see anything of worth since i haven't been using this filter all too seriously. The mod only helps to reduce the pink flaring that you might find in the corners or on the edges of the image due to the sun reflecting lighting from the side of the filter. I hope you aren't expecting to get better image quality , just less annoying pink flares.

That's what I was hoping. Really that's my only problem with the rubber band technique. If I can get my expodisk or something similar to work with this then it should be a pretty good ND10 filter. Or would that be an ND12 filter since I'm using my Shade 12 glass?

Here's my last one through welding glass. I just bought a Hoya x400 (I should have bought it months ago haha).

Nice treatment on that shot. Did the welding glass give you a taster enough to buy the X400 then? I bought the Lee Big Stopper because of the fun I had with the welding glass.

Is it possible to crack these with out being able to see the crack?

11mm 320 Seconds f/8 ISO 100

IMG_9522 by CameraMan65, on Flickr

24mm 400 seconds f/8 ISO 200

IMG_9524 by CameraMan65, on Flickr

Kind of disappointing...

Only part I messed up on was I accidently broke off a little too much off one side...

IMG_2037 by CameraMan65, on Flickr

The flipside

IMG_2035 by CameraMan65, on Flickr

I don't see any deep cracks in the glass that would warrant those markings. However there is a scratch apparent in the filter on #2 there towards the bottom of the filter...
