Welding Glass?

[Steeps]

Point is still valid

Measured my welding glass earlier 14.5 stops as best I can work out. Going to need some bright days or some bigger batteries!

Most of my shots from London were 30-45 seconds using ~12/13 stops with the glass (number 10), so 14.5 stops is quite a jump

At 14 stops 1/250th becomes 1 minute vs 4 seconds on a 10 stopper... It's all a bit silly but it's what I have.

If you get the glass from the guy on ebay and get a selection and decide to wash it before using it make sure you know which is which as the writing comes off very easily
