Welding glass, how do you attach yours?

Buy a step up ring and glue or tape it on. I made a card sleeve for the glass which stopped the light leaking and kind of a lens hood.
 
I paid a glazier £1 to cut it in to a circle for me then super glued it in to a 77-82mm step-up ring and packed the edges with blue tack to plug the leaks.
 
cokin adaptor ring and a sausage of bluetack - if you roll it into decent sausage and apply it in an unbroken circle you dont get any light leaks
 
Defo a step up ring, blu tack it instead of glue, so you can use different step up rings for different lenses.

Good idea my friend!
 
the other alternative is to pay a glazier to cut it to the size of a cokin p filter then just use it in a filter holder as normal (you may have to pack the sides with card depending on the thickness of your glass)

This is what i did with my p series for 3yrs!:) you will suffer from light leaking with welding glass though.
 
Out of interest, where do you guys get your glass? Online or local dealers?

Well it hasnt been too bad but i like the idea of glueing it to a step up ring. Will give that a bash.

Got mine from ebay ages ago for £1 i think.
 
Ebay couple of quid free postage too
 
I got mine from ebay at 1.50 free postage
And it fits in a cokin P filter holder nicely :-D
 
Really?! You guys use these for filters? I'm a welder why didn't I think of that, arggghh! :lol:

I'm such a noob. :bang:
 
i got my self 2 sheets last week only tested them out i got 14 and a 10

only tried the 10 out

i used the cokin filter attachment ring to the from of the lens with black tape, its just too thick for the holder but this works well for me

i had a ideato fix the colour cast but i dont think it has work, il upload it
 
its definitely worth a try loz - you usually get a weird cast but you can fix that with a custom WB
 
i was thinking of using a colour catcher to remove the cast

yea my glass is 4mm and i think the slots are 3mm

i dont want to use the holder any way, as you will get leak in the rear, so i put it on the filter ring, so its flush and tight to the lens

hoping this means far less reflections
 
oh ok
i think ill get a gasket type thing to go in behind it
 
i seen that on the proper filters,
but if you get a gasket will that fit in the holder ?
 
dunno
waiting for the holder its in the post at the moment
might just make something not actuarly buy a specific gasket
this will be my first filter holder
apart from my cokin A stuff
 
I tried tape around my cokin holder, but it wouldn't really stay put, so I recon I will glue a ring on to the welding glass itself. Not got anything decent yet because of the reflections and light leaking through the gaps, still got to work on the exposure times as well.
 
I used to use my petal lens hood in stow position then rubber band the filter on the front, using the shape of the hood to hook the bands to. Remove your uv filter as the knurling on them can create gaps. Don't forget to close your viewfinder shutter
 
i superglued my glass onto an adaptor ring over the weekend and although its rock solid now it looked like the fumes off the glue ate into the glass a little! There are marks around the areas of the glue blobs that can be polished out to a certain extent but they dont go away. Havnt tried a shot with it yet so not sure how much it will appear on the final image. But something to think about if anyone is going to try the glue on approach.
 
I just have mine blue tacked to a cheap UV filter (which I ought to remove the glass from really). I also taped the edges of the glass with black electrical tape to prevent it cutting me/my bag.

As for white balance, some will fix okay, mine REALLY won't. It's a shade 11, which works out at about 16 stops, which as side from giving exposures that are really a bit too long gives it a wicked green cast.

Same here, but not had great results TBH. I must be doing something wrong as I have seen some amazing shots taken by others.

That's a good tip about the tape

How do you work out the stops
I have a 10 and 14

An afternoon of trial and error.

I took a base image with out the glass first, then starting at 10 stops took more at 10-17 stops. I then compared the images in lightroom, the base was between 15 an 16 stops ish.

In practice I have started at +15 stops and check the LCD if that's close enough for me to just boost it in post as a 90s exposure is daft long for full mid day sun, think I was using a non base ISO also to try get the time down a bit!
