I bought an ND filter at flee mkt--what is it????

[splaaash]

I bought an ND filter pro "ND 2.7" 400X 😱 What is it???

I supposed 2.7 are the stops down??? But 400 X ---will self destruct at the 401st. image😱

Why not 2 stops or 3 stops why 2.7???? If that's what it means

HELP😡

9 stops, 2.7 optical density.

Yes, 9 stops, great filter for these lonely piers in the mist, if you want to join the queue generated by Michael Kenna. Don't forget about the reciprocity failure.

9 STOPS😱
I paid 5€---no wonder they sold it😎

It looks really good has a green tint....looks really cool...IF anyone looked😡 Indeed in sunlight its f3.5 @20th second😱

NINE STOPS gosh well it might be useful---

For those bright sunny days, when all you have is Ilford ISO 3200... 😎

more for those sunny days where need to expose for some seconds. there are not so many situations where you need to do that, but when you need, you need.

52mm?

Nikon sold them for photographing a solar eclipse. I have one, even used it once some years back.

For your info, a little discussion of the '2.7' numer. It represents 9 stops in the DIN system, where each stop is 0.3-

And then this company has a 400x filter, 2.6 not 2.7-

2-3 second exposures are possible in daylight. IMO this is the sweet spot for blurring moving water...

The only high density Nikon ND that was offered was an ND4.00 (13-1/3 stops), at least during the 1974-1995 period during which I ran camera stores. This matched the highest density that Kodak offered in their line of ND gels.

May I suggest an alternative? I'll stick my oar into the water.

My recommendation is to look and learn at how the function of a ND filter can now be performed during the process stage with a computer. There are several ways to achieve results that, to me at least, with a computer and a program such as Photoshop can offer many iterations.

Photoshop😱 costs 120€/$ then i saw when i last looked a year or two ago adobe insist on paid updates each month i think----

VERY expensive,i imagine many can justify the price and it seems to do everything But gimp and raw therepee are free

Though after printing and reading the instructions and watching youtube i cant really use it so i gave up RAW files a few weeks ago😎

Even paint or other programs are just tooo complicated,
