I've had this idea for couple of months now and the idea basically is to attach a welding glass before my camera lens and take photos through it just to show how world looks for me when i'm earning my daily bread at work. In case you're not familiar with welding or tools used with it i'm going to give you short briefing for that. Welding glass is used to look through while welding, because welding is something you really need to see what you're doing or end result don't meet given standards. Welding glass is basically very dark piece of glass which purpose is to darken the insanely bright light coming from electric arc created by welding burner. Welding glass works pretty much the same way as a grey filter that you can add to your lens but quality of welding glass as a filter isn't even close to those 100€ filters made especially for photographing so i thought it'll be interesting to see what kind of photos i'll be able to do with it .
First problem was the shape of the glass: it's rectangular so i really can't just attach it like a regular filter. First i tried to attach it with clear tape straight to the lens but that wasn't good because i couldn't take the glass off to point the camera and focus it. Welding glass is so dark, it's impossible to point the camera when it's attached to the lens not to mention focusing the camera... So, after thinking a while and looking through all my tools i have home i got an idea! I took that clear tape and taped the glass to the lens hood so i could took it off to point and focus the camera and after those were done and done i could put the lens hood back to it's place and it worked.
My camera is Canon EOS 450D with gorilla pod and i used the regular kit lens 18-55 and because the glass is so dark i had wired remote with me for longer than 30 second exposures. I used ISO100 and f/3.5 @ 18mm and tried 30 second exposure. Then i tried with same options but with f/11 but even 5 minute exposure wasn't enough so i went back to f/3.5.
Here's some photos.
This my camera with the glass on it
This is the lens hood with the glass
First shot. 30 seconds @ f/3.5
Placed the camera between these poles that are stucked to ground. 30seconds @ f/3,5
300 seconds or 5 minute exposure @ f/11
60 seconds @ f/3.5
30 seconds @ f/3.5
