How to shoot the feeling of water like silk with Canon 500D?

First, the exposure of a digital camera is determined by three parameters (shutter speed, aperture size and ISO (sensitivity) size):

The faster the shutter speed, the darker the photo will be, but it can capture the high-speed moving picture. The slower the shutter speed, the brighter the photo will be, but the moving objects in the picture will be blurred, and the shaking of the hand will also cause the whole picture to be blurred. For example, it usually takes more than1125 seconds to shoot a portrait, 1/250 seconds to shoot a person walking, and 1/600 seconds to shoot a person running.

In terms of aperture, the larger the aperture, the brighter the photo will be and the background will be blurred easily. The smaller the aperture, the darker the photo will be and the clearer the foreground and background will be. The larger the aperture value in the camera, the smaller the actual aperture, and vice versa. For example, the aperture of F2.8 is much larger than that of F8. F2.8 can easily take photos with blurred background, while F8 can take clear scenery photos before and after.

In terms of ISO, the larger the value, the brighter the photo, but the more noise, the worse the image quality. The smaller the value, the darker the photo is, but the picture quality is the most delicate. ISO is the last thing that photographers want to touch. As long as the ambient lighting is sufficient, it will be set to the minimum value to ensure the highest image quality.

Any exposure and effect are achieved by adjusting these three parameters. Let's talk about how to adjust the effect of "water flowing like silk":

First of all, this effect is actually the dynamic blur of water flow, which is the effect when the shutter speed is not enough. The slower the shutter, the more exaggerated the dynamic blur. When used in night traffic, a series of beautiful light strips can be obtained, and when used in river waterfalls, silky water flow can be obtained. When the shutter slows down, you can't hold the camera, and hand jitter will blur the whole picture, so you must use a tripod to assist.

Then, because we are shooting the scenery, we need to lower the aperture in order to ensure that the foreground and background are clear. The aperture value commonly used in landscape is F8-F 16.

Finally, ISO should be set as small as possible to ensure the finest picture quality.

After the above thinking, ISO can't move, the slow shutter brightens the picture, and then the small aperture darkens the picture. In many cases, the exposure may be balanced, but the lighting in the actual environment is not necessarily balanced. In order to adjust to the most suitable brightness, the aperture can be slowly adjusted above F8.

After the three parameters are set, put the camera on a tripod, construct a picture, and press the wireless shutter to complete it:
