Are there any great photographers? How was this photo taken? What are the relevant data (aperture, shutter speed, ios)?

The timing of this photo is very good, but the photographer's own skills can only be said to be very limited.

In fact, it really doesn't make sense to simply say parameters. Look at this little picture. The parameters are definitely unspeakable.

LZ should thoroughly understand the influence of ISO, shutter speed and aperture instead of guessing these parameters.

Let's cut the crap here:

ISO: The higher the ISO, the stronger the photosensitivity, and the required exposure time can be greatly reduced.

For traditional film, the lower the ISO, the clearer the picture. The higher the ISO, the larger the particles.

The benchmark sensitivity of Sony and Nikon is ISO 200. More particles above 200, less particles below 200, but lower than the benchmark value.

The image is calculated by chip, and extremely low ISO is not recommended for daily use.

Canon is even different. Canon's benchmark sensitivities ISO 160, 160, 320 and 640 all have better noise performance than ISO 100.

Because ISO 100 needs to be converted by 160, the noise of 125 will be greater. Of course, the dynamic range will be reduced by 1/3 stations at the multiple of ISO 160, so 100 is considered as a large light ratio and 160,320,640 is considered as an acceptable light ratio.

In addition, the change of ISO will also cause large deviation of tolerance.

Summary: Traditionally, the lower the ISO, the purer the picture, but in the digital age, it should be selected according to the model.

Shutter speed: There is no reciprocity law in this digital age. So the faster the shutter is, the less light enters. The slower the shutter is, the more light comes in.

Aperture: Aperture mainly affects three elements: 1. Exposure 2. Depth of field 3. Image quality.

The larger the exposure aperture, the greater the exposure.

2. The larger the depth of field aperture, the smaller the depth of field.

3. The picture quality is here, and the landlord only needs to know a few points.

When the aperture is fully open and the aperture is maximum, the lens quality is actually very average.

When the aperture reaches F8, the quality of this lens is usually the best. In F8, the dog head is great.

Some people reduce the aperture to F22 or even smaller in order to get greater depth of field. However, this is not desirable, because it may cause limited aperture diffraction, resulting in a rapid decline in image quality. The seriousness of this problem involves pixels per inch of photosensitive elements. For example, the limiting aperture of a 5D220 megapixel Quan Huafu is about F 16. After F 16, the image quality drops very quickly. The Quan Huafu of Nikon D800, with 36 million pixels, has not been carefully calculated, and the image quality may drop rapidly at F 1 1. The180,000 pixels of Canon 7D APS-C are also about F 1 1. So pixels are enough, and it is meaningless to blindly have more.

A lot of nonsense. Because the diagram is too small, I can't tell the detailed parameters.

I am 5D2 myself. If I shoot, the aperture may be F8-F 1 1, and the ISO remains at ISO160,320,640. And use the method of shaking the black card or RGND filter to neutralize the highlight area of the house in the middle of the picture. Looking at the lake in the picture, we can see that the shutter time should not be long. Personally, I think it is ok to blur the lake light and clouds with a tripod extension point.
