How does Canon 550D shoot night scenes?

Lead: Canon 550D handheld camera can also shoot beautiful night scenes without jitter as follows.

ф o1600, shutter speed113seconds,

Shooting data

EF-S18-55 mm f/3.5-F5.6 IS/Aperture Priority Auto Exposure (F5.6,113 seconds) /ISO 1600/ Exposure Compensation: -0.7EV.

Use ISO 1600 and ensure the shutter speed is113 seconds. At the same time, turn on the IS image stabilizer, and hold the camera stably to suppress jitter for shooting. Hand-held shooting also got clean night photos.

O 100, shutter speed 1.6 seconds.

Shooting data

EF-S18-55 mm f/3.5-F5.6 IS/aperture priority automatic exposure (F5.6, 1.6 seconds) /ISO 100/ exposure compensation: -0.7EV.

When ISO 100 is selected, the shutter speed is 1.6 seconds. Low shutter speed is prone to hand jitter. When shooting at night, if you feel the focus is a little blurred, it is mostly caused by hand jitter.

Relationship between ISO sensitivity and shutter speed

The relationship between ISO sensitivity and shutter speed is similar to that between aperture value and shutter speed. While increasing the ISO sensitivity of 1, the shutter speed will also increase 1. Even in the shooting environment with poor light, the shutter speed can be improved by adjusting the ISO sensitivity, so as to avoid hand shaking when shooting with hands. It is worth noting that the higher the ISO sensitivity, the higher the noise incidence. However, Canon 550D is equipped with the function of noise reduction through image processing to deal with the noise problem. When shooting at high ISO sensitivity, you can use? High ISO sensitivity noise reduction function? Set the level 4 noise reduction effect.

Effective use of ISO sensitivity to prevent hand jitter

By effectively using the high ISO sensitivity of Canon 550D, hand shake caused by hand-held shooting at night can be suppressed by increasing shutter speed. Generally speaking, the standard shutter speed for hand-held shooting is 1/ actual lens focal length (seconds). For example, if you use a lens with a focal length of 30mm (with an APS-C camera, it is equivalent to a focal length of about 48mm), the lowest shutter speed that can suppress hand shake under normal circumstances is 1/30 seconds. ISO sensitivity can be adjusted according to this standard. In addition, when installing EF lens equipped with IS image stabilizer, different degrees of hand shake compensation effect can be obtained according to the lens. Among them, the maximum compensation effect of the lens can be equivalent to increasing the shutter speed by about 4 levels.
