Very confusing photography problem, please advise!

The dynamic range is independent of the size of the photosensitive element. Think with your head. Don't listen to those who gasp with their ears. In addition to the influence of chip size on pixel size, it is the fineness of color. It's like you shine three different colors of light on three points and one point, which is absolutely different. The effect of three different colors of light within one meter is quite different from that within half a meter. The size of the chip determines this.

As for the dynamic range, I want to correct it. First, you need to know what the dynamic range is. Dynamic range is neither sensitivity nor tolerance. Is the density and fineness of color. You have to understand, the bigger the scope, the better. In order to get the best color reproduction, the SLR camera sacrifices a part of its dynamic range. For the simplest example, the dynamic range of Kodak pro negative film used in our ordinary camera is about 15, while the dynamic range of positive film used in filming is mostly 9. Ask those photographers if you don't believe me. The color of the manuscript is exaggerated. That's the point. But this is not an absolute advantage. Let's compare the old machines of Canon and Nikon. I use the poor machine D90, compared with 40D or 400D. The color reproduction of D90 is better than that of Canon. As for the dazzling exaggeration of colors, Canon exaggerates a lot. Of course, this is just an old machine. Color filters on Canon chips have always been my favorite. Filtered a lot of invisible light. Although the color is guaranteed, it loses a lot of fun in photography. This is beside the point. But these also reflect the dynamic range. Although Nikon also has a chip filter, it is not exaggerated to the point where it cannot shoot people with an infrared filter (lens filter).

A camera and a video camera are two concepts. A camera is the same as a movie machine. Those cameras that are only a little better than hand-held DV are completely incomparable. A friend in the circle told me. All the camera equipment within 50 thousand yuan is amateur. Equipment within 200,000 is a ticket game. I don't understand cameras. I won't say any more.
