Welding glass as ND filter...

[Spoooon]

I know there are plenty of instructables and what not for it. FWIW, what I did below:

Unfortunately, my stuff got here too late to do any real shooting.

Ingredients:

Shade 10 glass
77-82mm step up ring
super glue
electrical tape
Windex

1. I screwed on the 77-82mm adapter to my lens and marked where the vertical position should be.

2. Cleaned the glass and step up adapter.

3. Carefully applied "Ultra Liquid Control Loctite Super Glue" to the ring and placed it on the glass (with the mark oriented where I wanted it). While it set, I aimed a small desktop fan at it to blow away any fumes that could cause hazing.

4. Used the electrical tape to mask the ring to eliminate light leaks.

5. Plan to use electrical tape around the rim of the glass (only taped the bottom portion).

10 minute exposure, can't wait to use this in daylight:

Went out shooting a few hours ago. Unfortunately, the sky was almost solid overcast and I have limited options for really dynamic scenes. Will be forced to take another trip to Charleston, SC and get some more pier shots.

1. f/8, 49s

2. f/8, 57s

3. The first one converted to BW

4. unedited RAW, f/8, 143s

5. some PP

6. BW

Very cool. I like how the B&W conversions came out. Look excellent like that.

Very nice craftsmanship, I would have hacked it together much worse

Is there another option to balance the color cast better? The unedited RAW looks VERY green and the processed color versions are still really greenish.

I don't know that you can get rid of it entirely other than going black and white. These shots are kind of tricky, as it was so overcast, everything was flat and drab anyway.

Next time, I'm going to try shooting a white card and see what happens. And sent you a PM with a link to a DNG if you'd like to fool around with it.

Really cool! The color corrected are still a bit green but, and especially with these shots, it's kinda fitting imo. Makes for kind of a depressing look, which fits the overcast sky, old bridge and dead winter background.

There was a huge thread about using welding glass that really popularized this technique a few years ago. It was on a UK photography forum IIRC. They even named specific ebay welding glass vendors lol.

Thanks guys! Here's some more to check it from a few hours ago.

1. "Stairway to..." 5 minute exposure, welding glass filter

2. Same as above, color intact

3. 1 second exposure, no filter

4. Welding glass pointed towards the sun

5. Slightly different composition from the first shot, 140 second exposure

Get a nice tele and get a shot of the sun.
