Taking nightscape shots handheld with the settings set to a high ISO speed, a wide aperture, and a fast shutter speed can be fun too, but one of the true joys of nightscapes is putting the camera on a tripod and using a long exposure time to capture trails of light. Timing is everything for these shots, in which the light moving while the shutter is open draws trails across the image. Even if the trails don't come out quite as you expected, you can take a number of shots and then pick from among them later.
Here I captured trails of light from planes taking off from the airport in the sky over the Tokyo Gate Bridge.
The silhouettes of people who are moving during exposure are expressed as blur in nightscapes.
If the exposure time is too long, it won't be noticeable, so try adjusting the ISO speed, aperture, and the length of time the shutter is open to get just the right amount of blur. Also, your own silhouette illuminated by a streetlight can make for an interesting subject.
This is a function found on the CX4/CX5/CX6. It automatically combines multiple images taken at a high sensitivity and records the result, which reduces the camera shake and noise that occur when shooting nightscapes. It helps you achieve clear, beautiful nightscape pictures. You can enjoy shooting nightscapes handheld, without using a tripod.
