LAndscape shooting, water body slow shutter speed shooting.

[zamsar]

I'm currently using a canon 550d with 18-55mm IS lens. I've tried shooting in slow shutter speed eg. 10s to obtain the cotton effect when shooting water bodies. However, my shots are usually overexposed. And it is usually more than 2 stops. I've tried shooting a body of moving water at f8.0 and a shutter speed of 10s with iso 100,200 & 400 but all produced overexposed shots. Any bros here mind helping me?

I'm interested to know the answer too. But may I just ask what did TS mean by 2 stops?

Exposure is a balance between 3 elements, shutter speed, aperture and ISO. If you increase the exposure by using a slower shutter speed, but did not compensate with proper changes in aperture or ISO (or both), your picture will of course turn up overexposed.

Please understand exposure properly.

U can try to shoot using Tv mode, set to 10 secs and see if its possible to shoot. Try shooting when the lights are not so bright, e.g. dawn, dusk or at night. Or like others suggested, get a ND filter

Hi,

it costs $138 for 77mm...

u don't rush into it first ok.. else $138 gone... think carefully and make sure u need it.

edit: i got the 77mm for my kit lens which is 58 mm.. so i get a 58mm to 77mm step up ring ($10)... it is better for me in the long run just in case i buy a uwa lens... which are usually 77mm...

Try closing your aperture (e.g. f16), increasing shutter speed (maybe 5s enough to get smooth water), and set iso 100. Incidentally, increasing your iso will not help with the over-exposure (read the links by daredevil).

But if you're totally into the silky water effect, just get a ND filter like nightmare said.

Thanks for tne info.
Btw, how does a step-up look like?

 

[gohjialong]

A step up ring looks very normal, size depends on the thread diameter of course. Just that it has screw-in grooves on both sides.

Can go down to Cathay photo have a look.... Nd110 is a must for sure

 

[daredevil123]

you need an nd filter.

And also basic understanding of exposure.

ND110 is not a must.

Nothing is a must.

ND comes in a lot of flavors and a lot of brands. Use the correct ND (number of stops) for correct desired effects.

more popular ND filters:

1 stop - Hoya ND2, B+W ND101, Cokin P ND2, Lee ND0.3.
2 stops - Hoya ND4, B+W ND102, Cokin P ND4, Lee ND0.6.
3 stops - Hoya ND8, B+W ND103, Cokin P ND8, Lee ND0.9.
6 stops - B+W ND106
9 stops - Hoya ND400 (8.5 stops actual)
10 stops - B+W ND110 (around 9 stops actual), Lee Big Stopper.

Words of wisdom, Gentlemen. :thumbsup:

May I ask you guys how to determine the number of stops we need for different exposures? What are 'stops' actually?

ND filter for long exposures.

But before i bought my ND filter, i used f22 iso 100, which could get me between 2-4 secs exposure before getting blown.

nd filter to me is not just for water effects, if you do invest in one, can use for skies as well, making a crowd disappear etc. basically anything long exposures can do...

have fun!

cheers
