Ryan - So with a longer aperture and with the help of the tripod, would it help?
1) set high ISO (800 ok?)
2) EV -0.3
3) any other advise please let me know.

Hi Dayan, all of us started from a newbie some point or the other.
Think of
- shutter speed
- aperture
- ISO settings
As a triangular inflexible band that forms the basis of exposure
Any side you pull , something of the two has to compensate to make up the same exposure.
But each change in the 3 components will bring about a different image characteristics (which may or may not be desirable ). Example :
Shutter speed too low - motion blur for moving objects
Aperture large - thin depth of field, small - deep depth of field
ISO too high - noisy pictures
( there are other little changes that you will find interesting to learn and pick up as u read and shoot more )
A longer exposure on a stable tripod for a static subject will help prevent camera shake from ur handholding and getting you a sharper photo. You need a longer exposure time because the environment is darker, so as to take in more light
Try to use the base (lower) ISO. Which is often the cleanest. Usually ISO 100 or even 200. ( When the ISO goes up, sensitivity of the sensor is driven up at the expense of noise in the image, but allows you to use shorter shutter speeds )
Exposure settings depends on the scene
I cannot think of any other thing offhand except :
- paying attention to composition
- try to shoot near dusk to get better colors in the skies
- focus accurately, may be less applicable since now liveview is a boon to focusing, was horrid last time when i was shooting in darkness via the viewfinder
- stablised shooting on a tripod or sturdy surface, and even consider mirror lock up or time remote shooting to reduce vibrations even further - I find it abit too much actually heh
And many more that i cannot remember, or i am still in process of learning and discovering

One must never lose creativity.
