What is the difference between using welding glass and just stacking filters on the end of the lens? My initial thoughts would be that the optical quality of actual filters being stacked would be much better and though it would cost more, would be easier to work with and you know your getting good glass right off the bat.

I do like some of the welding glass results that are popping up in this thread though..

Main difference is cost, my set up cost about $10

$5 for welding glass.

Real filters are more expensive, but have two or three advantages.
- they are more color-neutral
- they give less reflections (you could get an inner reflection between filter and front glass)
- they normally have better optical behaviour (more even thickness of glass), but some welding glass can be excellent

Stacking multiple ND is ok, if you have a longer lens. But when going more wide-angle, then the stack will often be too thick, resulting in darker corners.

You might want to Google "Harris Shutter" which is the technique you're describing.
Sounds like fun. You should give it a go.

I've seen them before. But I didn't have a name associated with it since it was a couple decades ago. With a name (thanks) Google pulls up a lot more. But like what I saw in the past, these are overly "crisp". I'm wanting a more subtle look where instead of stark red, green, and blue, I get smooth shades of color. That is the hope with the longer exposures.

I tried these tricks with multiple exposure in a film camera with gel filters many years ago. One involved lightning shots (red, green, and blue strikes). That's where I decided I needed to find a way to avoid the stark red/green/blue issue. But working with a film camera that had to be manually re-cocked while holding another lever to avoid advancing the film did not work to well as the film did juggle just a bit and alignment was lost. This was back in the day when the first Mac came out in black and white, and I did a trick that made them come out in color under a triple RGB exposure. It still had the alignment issue and unfortunately most of the film work back then was lost.

One effect that could not have been (easily) done on film was the black and white variation. In digital PP you just make the shots into black and white first, then do the mix into color channels. To have done that in film would have been "labor in the lab".

I guess now armed with a name, I should re-do some and start its own thread under that name ... though ones with welding glass or other ultra-ND long exposures could come back here.

Update: I started a thread for the color effects: https://photography-on-the.net …/showthread.php​?t=1291727

What about those metal film filters they recommend for viewing solar eclipses? How color neutral are they?

And how easy is it to correct for color problems? Can we start with a color chart in the scene in a first and last shot, and adjust to bring those colors into correct rendering?

well i picked up some welding glass...then took a cheap screw on hood that i had bought, and cut off the hood part, and glued the glass to the remaining part, so it just screws on now...not sure if i'll try and cut the glass or just leave it big...might give it a go later, just wish there were some clouds in the sky today

You don't actually need to stack multiple filters to get the effect. You can buy VERY dark neutral density filters. I use the Lee Big Stopper which is 10 stops. But it's wicked expensive and usually on a 6 month back order. I got mine in 3 months and was happy it only took that long :-) It is an amazing tool.

That being said, I love this thread. The creativity of photographers never ceases to amaze me.

Cool! Love the purple shot. Great to see lots more people trying out the glass in this thread too :)

here's a few from my first go around...i don't always shoot raw, so the first one was just corrected with levels...I started shooting Raw after the first couple though...much easier to attempt to correct...but still need practice...either way I liked the look of B&W for a lot so I went the lazy route :)

Hello everyone! Been reading through this whole thread the last few days and I finally fashioned myself one of these filter! I used a rubber lens hood glued to a #10 piece of glass. I went out and tried it a bit today and here is the result.....Hope you like!

Gotta be honest, these welding glass shots have inspired me to pick up my camera again and i must say, having bought a few shades i find them amazing for the money.

For some reason i get more pride from taking a great shot on the cheap!

Hi,

This thread is indeed interesting and informative, thanks to all.

I have my pieces of welding glass and will be trying them out soon.
One question relating to a 7D though.
Does the mirror lockup accessed by the custom menu only work for one shot and has to be re-applied all the time?

Thanks.

As long as the custom function is enabled the mirror will lock up before each shot. You will either have to press the shutter button twice, or use the 2 second delay for each picture taken.
