Hi,
Would like to know how come the pictures turn out so grainy
Heres my setting:
Camera: Nikon D90
18mm
ISO200
F22
Shutter 20s
Standing on Tripod.
Remotely triggered

there is not really a need for the aperture to be so small..

try f/11 at 15 seconds, ISO 100. comes out pretty good everytime for me.

also, the "noise" might be compression artifacts. you set your picture quality on raw or fine or normal?

where is the grain?

i see some possible jpg artefacts, that is all
 

It's you. Your expectations too high. :bsmilie:

I see no grain either.
 

i see no grains. maybe its your monitor or application setting problem?
 

It's not grainy, but at f/22 you're encountering diffraction on your lens already, thus the reduced sharpness.
 

The photo too small to notice noise. Also JPEG artifacts and diffraction problems are mentioned by others.

If have noise, it may be contributed by Active D-lighting if it's on.

Camera: Nikon D90
Exposure: 15 sec (15)
Aperture: f/16
Focal Length: 105 mm
ISO Speed: 200
Exposure Bias: 0/6 EV

my guess is, u dun need 20s shutter speed?
 

f22 is a no-no in night photography, but is more useful in daylight landscape...
in your case, it basically dims out almost most of the lights...
use the lowest iso for night photography.

if you mean noise...then i give u my half-past six knowledge on noise:
1) try to avoid using such a long exposure time. this is due to sensor heat up. not sure how well d90 handles this.
2) noise often happen in shadow details. read up on SNR (signal-noise-ratio).
3) noise occur on large areas with similar tones, such as the sky for this one...

btw.. where is the noise? :p
