Welding glass, how do you attach yours?

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!

thanks for the top tip
 
£1.50 is a tad expensive, 60p is nearer the mark for a 4 1/4 x 3 1/4 lens, all shades 8-13.:thumbs:

Hmm.. Buy a ND400 filter seems like the simplest way.

The exposure was 30 seconds long. I will probably get a proper nd at some point, just not rich enough at the moment :lol:

Do you have a link for the 60 pence ones :thumbs:
 
I used a 10 at f12 at 100 iso or something and it was 4 mins
 
i just use a cheap push button no power needed does the job great
