funny!

I wonder if the have a reverse filter for adding people into shots. Think of all the CG money you would save with crowd enhancements if you could just pick up on of those babys.
 
I know people are thinking this is a joke, but ... guys, that's an ND 6.0 filter! It probably does do exactly what they're showing.

ND 6.0 means that it blocks 20 STOPS of light! 20 STOPS! Useless for cine, obviously, but for still photography you'd be able to set your shutter speed to an extraordinarily preposterously long duration -- and because of that, people would blur out of existence as they moved around.

Let's take a typical shutter speed of 1/60th. If you put on a 20-stop filter, you'd have to open up the shutter to 16,384 seconds (or 272 minutes, over four and a half hours) to get proper exposure.

I dare say that yes, the people and crowd at the bottom would blur into nonexistence at that point. The photo sort of shows that effect, there's blurry smudginess down there where the crowd would have been. What they're not showing is the sky effect, obviously you wouldn't get crisp clouds like that if you had a 272-minute exposure!
 
I'm gonna get two of them and wear them like glasses. It should make my work day go a little better.:beer:
 
Why you ask? I've been using one for years, definitely wont work with video as normal daytime shutter speeds start around 20- 30 seconds and depending on F-stop you can get your shutter speeds down to 2- 3 minutes, during the day. This makes everything that moves simply dissapear. I love the filter for city scapes and such that give you the serenity of a night time shot with the light and depth of shooting during the day.

But if everything that moves ends up blurred out... how does it look? Is it worth it?
Can you post some samples?

Thanks,

Well said! ...(as usual).

I didn't catch that until I read your reply. I'm used to using .6ND gels, etc. It's all about the placement of the decimal point! :thumbsup:
 
Thanks Barry.

Good info. It was still a lot more fun when I thought this was a .6 ND filter that had a people removing option :)
