Welding Glass picture thread. (Random)

[Pixel-Snapper]

Big thanks to AndyKH once again for send me the glass. Not once but twice no thanks to RoyalFail for smashing the first into a million peices.

Had a play with the 10stop welding glass plate on saturday. Sky was a complete white out so no chance of playing with the clouds just yet. So thought I'd pop down the stream to fire a few off and get my head around the technique.

It was really dark down the field to start with so had to ramp the ISO to get anything other than a black picture. Next investment will have to be a remote shutter release, tryed bulb by holding the button down with my finger but got too much vibration and it looked pap.

I know theres a few more out there with welding glass so come on show us your pictures.

[Gad-Westy]

Good effort! Do you mind me asking how you attached the welding glass to the lens?

[rasputin]

Just found mine the other day, so I'll need to get out and play with it!

I attached mine to a step-up filter adapter (so it can screw straight into the lens filter thread). I taped it down with electrical tape so that it would block all light from the edges of the filter.

[Pixel-Snapper]

At the moment very steptoe.

Started out with two elastic bands. One that went around the eyepeice and the other around the bottem of the camera, found that this wasn't secure enough so made a sausage of bluetack to go inbetween the glass and lens along with the laggy bands.

Found this to be adequate means of doing things, I was going to buy a adapter ring and glue the glass to it but this way I can change lens easyer if needs be.

As long as your gentle with it I cannot see it being a problem.

I got one too and have used it a little. It does give a massive green cast so I've been converting to greyscale. Here's my favourite so far:



and here's the hi-tech setup

[Pixel-Snapper]

Good work Dave, I need a cable release really and I use the same setup as you.

Colour cast can be over come by using a custom white balance.

Easy to do with the canon 40d, you take a picture on a white peice of paper infront of the lens with the WGP on, then go into your settings menu and find the CWB setting, then select the image you've just taken and it doe's the rest for you.

Couldnt quite make out what body your shooting with but I'm sure there must be something similiar.

It's a 400D. Yes it has a custom white balance function I just haven't tried using it yet! Will do next time

[daveake]

p.s. I got the cable release on ebay for about £20. It's an intervalometer too - you can set up the shutter time, time between exposures and how long to repeat for. I want to use it for doing star-trails (in a couple of months when we next get a clear sky!).

I Blutack the glass to a Cokin P series adaptor

Cracking shots there John.

Cokin P adapter looks like a good idea too.

[arej]

I used the Cokin P adapter ring for mine - bought a spare bit of welding glass as they are so cheap and a spare adapter ring (e.g. here for £1.99 off ebay: http://cgi.ebay.co.uk/72mm-Adapter-Ring-Filter-Hol... ) and superglued them together so absolutely no light leaks. I had been doing the elastic band technique previously but had issues in bright sun sometimes.

I was about to say, try sticking the camera on a tripod/something sturdy and using the self timer option to eliminate any wobble when pressing the button. However this will limit you to using the slowest setable shutter speed (max 30 seconds iirc on the 500D, yours may be different.)

First attempt. Need to avoid shooting at the sun to get a longer exposure to really smooth the water out and smear the clouds.

You're more than welcome Pixel-Snapper, and anyone else who got one from me (I can't remember who got one now). I havnen't been out with mine for a while now. Here's my first couple.

Yes both shots I posted where at 30secs on a tripod, which is the longest you can go without then using bulb. Which is why I had to leave it on 30secs at f4 and up the iso to 1600 to get anything to come out, which is also the reason for the amount of noise.

I could of easily got the same shots without the welding glass at a much better quality but that would be defeating the object of the exercise.

[Adz The Rat]

Im liking these shots in here!
What length exposures have you been using?
I really must buy a remote for mine.

[james_tigerwoods]

I'm loving these - where can I get some glass from and is there a "guide" for how to use it?

[AndyKH]

My exposures were around 2mins 40s and upwards. No real guide, just compose the shot with out the glass, then once happy carefully attach the glass to the front of the lens and fire of a shot on bulb. You'll need a remote trigger though that will keep the shutter open long enough.

James, go to Machine Mart or any of the welding supplies factors, the numbering of the welding glass does not directly relate to a ND10, the nearest is generally the No8 glass whilst the No10 is approx ND12-14 sort of level
They will only cost a couple of quid

Ahhh I'll do just that - Thanks
