How to adjust the aperture sensitivity shutter speed at night shooting landscape square dance. Improve the level of shooting respectfully ask connoisseurs to teach.

Night shooting needs to ensure the clarity of the picture, open the aperture to the maximum, is to adjust the value to F5.6 or F4 or F2.8, anyway, is adjusted to the limit. Sensitivity adjusted high on the quality of the image has an impact on the conditions to ensure that the shutter speed of the sensitivity as low as possible. There is a term, hand-shock limit: shutter speed ≤ 1 ÷ focal length, so that you can try to make the photo will not be false. Shooting night landscape is best also need a tripod and flash. A tripod provides stability, which is especially important when shooting night scenes. It is also necessary when the exposure time is long. When photographing people at night, it is best to use a flash if conditions allow. Will be placed in the dark, the light or something behind the characters at a certain distance, the background metering (with M stops), and then light flash characters, so that even if the background requires a long exposure time characters will not be false. If it's a snapshot (you da situation), it's still best to use flash. If you don't want the character to be disturbed by the flash, then increase the sensitivity. Anyway, being able to record the image and take a clear picture comes first. I hope this helps. I'm not sure if this is a good idea or not.
