I don't understand your question?
 

as what i read at wikipedia, the shutter speed are, 1s, 1/2s, 1/4s, 1/8s, till 1/1000s.
For my nikon, I got 1.5, 2, 4, 6 and up till 4000

So how i convert them?

It sounds like your going through the fractions of seconds? 4000 is probably 1/4000th of a second, 6 = 1/6th of a second? ETC? Should outline that in your user manual/guide.
 

D90 manual didnt state.
Hmm. So how do i convert them?
 

Hi yiyong321,

On the camera, when it says 4000, 2000, 1000 that actually means 1/4000, 1/2000, 1/1000... when you turn the main knob in clockwise position and get 1", 2", 3" then that is 1 second, 2 seconds, 3 seconds.

Hope this helps,
WK
 

Basically, if it says 200 it means 1/200, 400 means 1/400. 1" means one second and 2" means 2 seconds
 

but what does 1.5 means? and 2,3,4,6 should be 1/2, 1/3, 1/4, 1/6?

Without knowing in what direction you are turning your dial, it's hard to say what's going on. What does your manual say in the "shutter speed" section?
 

Shutter speed conversion? :think:
Which mode are you at? ISO? :think:
 

Im using ISO200.
 

Im using M mode, :D
 

I just check out wiki, if you read carefully, they state 1 stop. Those are just typical 1 stop values, cameras will have much more shutter speed options, in increments like 1/3 stops, instead of the typical 1 stop values shown in wiki.

So 1.5 in your case simply means 1/1.5s. There is nothing to convert, 1/1.5s is still 1/1.5s for your D90 or whatever camera you can think of.

I second what pchmj said. D90 has either 1/2 steps or 1/3 steps depending on your options. If it is 1.5" that means 1.5 seconds, if it is 1.5 that means 1/1.5 seconds.

madmartian | he's not talking about adjusting exposure. Just what the numbers 1.5, 2, 4 etc. means in terms of shutter speed

Both irrelevant.
Pushing your topic to Google revealed two hits, stating the shutter speed specs and 2 remarks: increments can be changed in 1/2 stops and 1/3 stops. Read up about exposure stops.
The Wikipedia site about Shutter Speed lists the full stops.
Read your manual, again, slowly :)
 

cnt stress enuf the importance of reading thru manuals for 1st time DSLR users:sweat:

I was thinking on that line too as what pcmj said ;)

Awesomely said. hahahaha.
TS, you should really read up on some basics of how a dslr/camera work before getting it. but then again, if you have it now, you should read on your User Manual. It has more than enough information for you. lol. :bsmilie::bsmilie::bsmilie:
