Spurred on by this thread I have obtained my Welding glass,no.8 and no.10. I was suprised to find the edges allready polished smooth. Using plastic insulation tape to attach to a suitable filter ring seems to give me a good handy fitting.
Now the crunch,I,m a bit stumped by the white balance bit. Should it go something like this-using a Sony A57.
Attach filter-select custom white balance setup-point at grey part of sky and press shutter to select.
Having determined settings without filter,dial in an extra 10 stops and bang away.
If I get anything half as good as I have seen on here I will be well chuffed!
