How to take pictures of water with a Canon 500D that makes it look like silk?

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

The faster the shutter speed, the darker the photo you will get. , but it can capture high-speed motion pictures. The slower the shutter, the brighter the photos taken, but the moving objects in the picture will be blurred, and the shaking of the hands will also cause the entire picture to be blurred. For example, taking portraits usually requires a speed of more than 1/125 seconds, taking pictures of people walking requires a speed of more than 1/250 seconds, and taking pictures of people running requires a speed of more than 1/600 seconds.

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 front and rear background will be. The larger the aperture value in a camera, the smaller the actual aperture, and vice versa. For example, the F2.8 aperture is much larger than the F8 aperture. F2.8 can easily take photos with a blurred background, while F8 can take clear landscape photos before and after.

In terms of ISO, the larger the value, the brighter the photo, but the more noise there is, the worse the image quality. The smaller the value, the darker the photo, but the image quality is the most delicate. For photographers, ISO is the last thing they want to touch. As long as the ambient illumination 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 flow like silk”:

First of all, this The effect is actually the dynamic blur of the water flow, and the dynamic blur is the effect produced when the shutter speed is not enough. The slower the shutter, the more exaggerated the dynamic blur. Use it when there is traffic at night to get a string of beautiful light lines, and use it on the river. You can get silky water when you fall. You cannot hold the camera when the shutter speed is slowed down. This will cause the shaking of your hands to blur the entire picture, so you must use a tripod to assist.

Then, since you are shooting landscapes, in order to ensure that the front and rear backgrounds are clear, you need to close the aperture. The commonly used aperture values ??in landscapes are F8-F16.

Finally, set the ISO to the smallest possible value to ensure the most delicate image quality.

After the above thinking, the ISO cannot be moved. The slow shutter speed brightens the picture, and then the small aperture darkens the picture. In many cases, the exposure may be balanced, but the illumination of the actual environment is not necessarily certain. In order to adjust To achieve the most suitable brightness, the aperture can be slowly adjusted to values ??above F8.

After the three major parameter settings are completed, put the camera on the tripod, compose the picture, press the wireless shutter, and you are done:
