# Thread: what does 1/10s mean?

1. ## what does 1/10s mean?

i see a lot of post on the fujifilm f31d with their shutter speed (i think) set at speeds like 1/10s, 1/60 etc.. how do i set mine to this speed? i only see settings like 1.6, 1.3, 1" etc...

anyone can enlighten a newbie like me?

2. ## Re: what does 1/10s mean?

10 = 1/10s = one-tenth of a second
10" = 10s = ten seconds (the " denotes seconds)

So if you see a number like 25, it means 1/25 of a second.

thats how long the shutter stays open during a shot. if you are getting 1.5", 1" means the shutter opens for 1.5sec and 1sec respectively. when you see just 10 without the "(10)

it means shutter opens for 1/10 seconds... think of light as water, aperture as opening, and ISO as flow rate.

say your setting is ISO200 at f2.8, 1/5s....so in order to decrease the aperture opening time, you can either open the aperture wider or increase the flow rate. since 2.8 is already the widest opening, that leaves you the choice of increasing the ISO. from 200 to 400 you have doubled the ISO, so now the shutter will open for 1/2 the time of 1/5 which gives you 1/10 seconds.

think of filling a pail w water considering ISO(flow rate), aperture( f2.8, f4 etc) and shutter speed( how long to saty open)...changing either of this will affect the other....

wah... cheems.. haha.. but thanks.. that will take me a while to digest....

That's basic in photography. Got to know this by heart cos whether you are using a PnS or a DSLR, these basics still apply.

If u keep seeing 5, 10 and 20 for the shutter speed while taking photos, that mean you will get blur shots easily. Try to increase the ISO and get the speed like 60 or faster ...

Hi Nestor,

agree with Galdor that getting the correct exposure is a basic concept in photography.

Yes, it can be confusing at first, but it soon becomes second nature if you figure the pattern out.

Get a good basic photography book to go through the steps. Try one of John Hedgecoe's......I used some of them when I first started photography and he's rather good at explaining things.

Basically it boils down to the concept of "stops". Shutter speed and aperture can be thought of as "stops". For any given meter reading (the correct amount of light to allow to hit the film/CCD), you can choose to adjust any of the 2 components to keep the amount of light entering the camera constant. Failing which, you can choose to compensate by making the film/CCD more "sensitive" to light in a dark environment by using a fast film (high ISO number, requires less light for a said exposure), or less "sensitive" to light in a bright environment by using a slow film (low ISO number, requires more light for a said exposure).

The catch is figuring out the numbering system for the "stops". Fortunately, this is quite a graceful system (check out the aperture markings on your lens, as well as the exposure times for your shutter reading). Notice the "doubling" pattern? The same goes for ISO.

I'm sorry I can't be more helpful, but I was never eloquent with words. I hope this helps more than it confuses....

But do try reading an introductory book on photography.....happy shooting

I see it abit differently lah..

Aperture is size of water tap's opening
Shutter is how long u open it
ISO is the rate of water that enters ur pail

Shutter n ISO, to see 1 stop is clear, just double or half the value.. Aperture is abit trickier.. powers of sq root 2

Thanks for all the advice.. i think i'll go library and get myself a book to read up on...
