Hiya...

Are those images with lights stretched in the dark, (often look like they have been taken from a footbridge on the motorway) taken by increasing or decreasing exposure?

if yes how would one go about doing this on their camera - fuji s9600?

do you open the aperture to the maximum ensuring shutter speed is at a minimum and just snap away?

if yes, once you have pressed the capture button on your camera do u have to hold it extremely still until the image registers on the camera?

pls help n clarify

thanks in advance...
 
are there tripods for the s9600? I bet they are expensive....

Damn!!!

I just started saving as well and I refuse to stray...

grrrrrrrrrrrrrrrrrrrrrr
 
viper and mohain thats exactly what I wanna do....those light trails are great I like yours especially mohain..

how does it work to be precise?

is it low aperture like raymond suggested so f2.8 or higher? and then slightly longer shutter speeds?

As I have never done any is it trial n error?

Or can you advise any tips so I can get good clean light trails?

please advise

cheers
 
basically small apertures are the big numbers. it seems wrong because we quote them incorrectly. We say f2.8 and we should say f 1/2.8.

thanks for that...sorry I realise my error :)...still learning all this fstop / shutter speed stuff

the lower the f number, the larger the aperture therefore allowing more light

and vice versa...

I shall have a play...shame my garden doesnt look out onto a field with lights that way I could really get the hang of light trails..

To slightly change the subject...How about ISO? Is that basically fixing the amount of light the camera automatically allows? Is there a rule you could use so for example for night photography use higher ISO and for day photography with good lighting use a lower ISO? How about when taking images of people? Or is it all down to the amount of light already present when initally taking piccies?

Please clarify

thanks for all your responses peeps :)
 
cheers messiah most appreciated...

can you clarify on the following point you made :-
One way to think of iso, is imagine it like the volume control on a cd player. As you turn it, the sound will get louder, but any background noise and hiss will also get louder.

if the noise and hiss can be cleaned up on using photoshop? or is it best not to think like that to avoid having to touch up / clean up your pictures ?

would you say its best to be of the thinking the cleaner the image the less you have to touch up, as sometimes no matter how hard you try you will never get it 100%

What do you think?
 
does lowering the ISO automatically lower the shutter speed? what effect does lowering the ISO have on the aperture then?

If light is bad at night, if u use the flash with lets say a 800 ISO or a 1000 ISO would the shot come out better? i.e. would it compensate for the poor light?

pls clarify

thanks so far
 
alexisonfire...cheers for that, thats very helpful indeed...
