I recently got an ND400 neutral density filter for my lenses. This is an almost black filter that cuts the available light by a factor of 400. It looks black, and lets through only the barest amount of light, like welding goggles. With it, you can take really long exposures when there’s too much light to do so otherwise. This is useful for things like ocean scenes, when you want the waves to blur out into a misty ambience. It’s best around sunrise or sunset, but I went out today in the middle of the day to test it out. Here are a couple of the results.
Very nice! Can I use these in my rotating desktop backgrounds?
Can you get a second and stack them to get an ND16000?
Stephan: Sure, if you like.
Tom: You *could*… Exposure time in full sunlight would be of the order of 8 hours then though….
Thanks! I like the default Ubuntu backgrounds but they’re starting to look a bit familiar and these would fit with them very nicely.
Now if I could only remember where those files were stored…
