Mike Smith om "Long Exposure Photography"
Mike er god til å forklare:-)
Haha!! If I was a rich man I would ... unfortunately YouTube doesn't pay that well ... 😫🙈 ... I am planning something though. 😀
Ah, so I didn't explain that properly.
When it is under exposed, you need to add one stop of light for each step, and it works on a logarithmic scale.
So in the example I gave, it went from 30 seconds to 2 minutes, because to add one stop to a 30 second exposure, you double that to 60 seconds (one minute), and then double it again, so 60 seconds x2, giving two minutes.
If you needed to add another stop of light, you would have to double that once again, so 4 minutes, and then another stop would be 8 minutes. so every time you add a stop of light, you have to double the exposure time.
Does that make sense? - Mike Smith
