today good mood, explain for youAm a newbies, can any one tell me wat he meant by stop. Many thanks!
" I calculate the shutter speed by adding 9 stop to the reading that i got before i attach on the filter. "
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
got meh? I thought normally I beri good boy! :angel:Today your mood largi good. Normally you'll shoot first then slam later. Haha...

Welcome! Now "pay it forward" by teaching someone elseHaha...thanks for ur good mood. Many thanks!
maths fail har?Okies u see ar, I go calculate liao
2x2x2x 2x2x2x 2x2x2=18 rite?
Than the actual shutter is 1/20.
How come he added the 9stop Liao, The shutter speed become 25sec? Pls highlight again...so sorry..
maths fail har?
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 18????? are you sure?????
exactomundo!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?
exactomundo!

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.Hihi. U still good mood or not? Last Q from me
Tat is do u know how many stop is for
Hoya 77mm Circular Polarizer HD Hardened Glass 8-layer Multi-Coated Filter?
CT bro, I read your explanation, not only TS confused but ME also confused :sweat: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.
