hi people my apologies if this has already been answered - but i cant find the answer.

im trying my hand at long exposures with welding glass but i am stuck at using the correct white balance settings.

i've read this thread 'TUTORIAL: Using Scale 10 Welding Glass Effectively' by jamie p but he uses canon -

he quotes- ''Chose the photograph with the green colour cast and press enter/ok.
Now the camera will inform you to change your camera to the custom wb, opposed to AutoWB.

Once you have your camera in CustomWB take another photo with the same exposure as previous and you will now have a very nice image with no green''

so how would i go about setting this up on my d90.

i have also just bought hightech hard 0.9/soft 0.6 to start me off...

hope someone with more experience than me is able to assist many thanks :D
 
I wouldn't bother messing around with this if you shoot in raw. You can do this one click of a button.

It's just a custom white balance - see handbook.
 
I'd be aware that some welding glass will leave such a strong colour cast that it cannot be corrected properly at all. Certainly, the glass I use is good only for black and white images as it always leaves some residual cast. I don't mind - for a few quid it's a fun thing to use, but it's not something I'd use to capture the colours at sunrise or sunset!
 
The way I adjusted the WB for welding glass with my bridge camera was -

with the welding glass on the camera switch to live view and point the camera at a well illuminated white wall. If it is sunny you need to do this well away from sunrise or sunset to avoid the effect of the colour of the sunlight.

Go into the custom WB menu and change the custom setting until the wall looks white in live view, then save that setting as the custom WB for the welding glass.

A bit of a late reply, sorted my welding glass wb on my d90 today.

Select wb- pre then press it until it starts to flash, using a cable release with the lens wide open i locked the shutter open for 2 1/2 mins ( pointed at some bright white a4 paper) all this with pre flashing.
After the desired time i closed the shutter, i tried a 3 min exposure just in the garden and it seems to have removed the cast.

So hopefully i'll be testing it properly tomorrow.
