For a night shot the camera has to be sitting on something – preferably a tripod. Use the self-timer to release the shutter. Since you will be using shutter speed to slow to hand hold you usually do better with the lowest ISO and a longer shutter time.

I would start with f2.8 and 4 seconds at wide angle. If you are using telephoto the widest aperture you can get is f5.2, so start with at least 8 seconds. For cityscapes with a lot of light you might want to use a lower shutter speed and for dark situations use more. You can go all the way to 30 seconds in manual. If you need more depth of field you can use a larger number for the aperture and use a longer shutter speed.

For a distant night shot go to manual focus and set it on infinity. The auto focus has problems in the dark with distant targets. Look in your manual and see how to make sure the low shutter speed noise reduction is turned on.

Digital pictures are free. The meter will not tell you how much shutter speed to use at night. Vary your shutter speeds and see what looks best.

For daytime landscapes the best place to start is to put the camera in auto mode and half depress the shutter. Note the shutter speed and aperture. Go to manual and set as close to that as you can get. You will see a + or – EV. If it is plus you need a larger number in the aperture or a faster shutter. The opposite if it is a minus. After a while you will learn to judge pretty close where to start.

Here is a good explanation of the relationship between Shutter Speed, Aperture, EV, and ISO.


Click on the thumbnails for a larger image.

Once you understand the relationships, try different values and see what works in various light conditions.
