today good mood, explain for you
increasing exposure by 1 stop doubles the amount of light entering the camera.
decreasing exposure by 1 stop halves the amount of light entering the camera.
2 stops is 2^2 = 2 x 2 = 4 times (or 1/4)
3 stops is 2^3 = 2 x 2 x 2 = 8 times (or 1/8)
eg. all other things constant, changing from 1/60s shutter speed to 1/30s doubles the amount of light entering, so is an increase of 1 stop exposure.
hope that helps

STOP is the signboard you see at the roadside, and Highlights is what your girlfriend spends $150 on to do to her hair !!!
Hahahahahahahaha
Just kidding
It comes from the old skool of "click-stops" on manual lenses
and on the Greyscale, the 10 value is what is called highlights
Hope this helps
Cheers

Hahaha....My math reali fail...
2x2=4 4x2=8 8x2=16 16x2=32
32x2=64 64x2=128 128x2=256
256x2=512
512x0.05=25sec. Correct?
2x2=4 4x2=8 8x2=16 16x2=32
32x2=64 64x2=128 128x2=256
256x2=512
512x0.05=25sec. Correct?

this is a really good explanation there.
Hmmm.... ts still seem to be very confused.
I just add on a little.
This f stop thing is the "common way" of describing the aperture, amount of light entering the camera and depth of field. Read this link.
In this case, it is used to describe the amount of light entering or something like that.
For example, 1/60 seconds
Increase by 1 f-stop by controlling the shutter speed as explained in the quoted bold words.
to increase a 1/60 sec exposure by twice the amount of light is 1/30 and this is increasing by 1 f-stop.
Increase by 2 f-stops, 1/60 seconds will be 1/60>1/30>1/15.... 1/15 seconds of exposure.
and so on for 3 f-stops.
So, if you add a 9 stops filter, a 1/60 second exposure (long enough for a proper exposure) it will become a 1/60>1/30>1/15>1/8>1/4>1/2>1>2>4>8......... a 8 seconds exposure.
more readings for you

Haha yes still good mood, but I wouldn't know how many stops of light it cuts out. Typically CPLs allow the camera meter to measure accurately still, so just trust the meter reading. No need to calculate.
CT bro, I read your explanation, not only TS confused but ME also confused :sweat:
Meaning I no to need do those math mad calculation tat u teach me ar? Just let camera meter to do tat for me? Unless is a other filter like ND than I need to do those calculation? Can I say tat? Sorry for my stupid Q again...
Thank for the link! Am study it now. Hihi just wonder is it the rite way or not, cos normally I will set my aperture at F22 while snapping nite view. And I will stopwatch myself for the shutter speed. And slowly from the pictures I took, I will decide to add on or less on the shutter speed. Is tat the rite way?
Dear sino238,
Concept is correct, but f22 at night?????
Sheesh !!! try using only f5.6, or f8 max.. Otherwise, everything will be streaky !!
Unless of course, that's the effect you want.
