How does Nikon 3200 take high-definition pictures?

The first question is whether the focus is accurate. Relatively speaking, in addition to ensuring the stability of the camera during the exposure time, the effect of shallow depth of field will be strongly blurred when shooting with large aperture, and the effect of shallow depth of field will be strengthened when shooting with long focal length, so the influence of aperture and focal length on depth of field should be considered on the premise of accurate focusing; First of all, see if the clearest focus of the whole photo is in the clearest position you want. If not, it is a question of accurate focusing. If so, the display ratio of 100% on the computer is acceptable and clear. If you have to zoom in, the final result is just a colored grid.

Accurate exposure is consistent with what the human eye sees, indicating that the camera's metering and exposure are more accurate, and of course it also includes the technical proficiency of the operator;

But in many cases, the camera can't restore the light intensity scene in Gao Fancha. Because of exposure latitude's problem, the camera is simply too weak compared with the human eye. The human eye can observe the bright light and dark light in the same picture at the same time, but it is difficult for the camera to show it because the contrast is too big and the tolerance is not enough;

Many times, in order to reflect this contrast scene, the camera can only take into account the main performance part, abandon the unimportant background, and adopt different metering methods, exposure compensation and other operating methods to subjectively restore a scene. This scene will be different from what our eyes see, but there is no perfect solution. Higher-end models, higher-end hardware configuration will be slightly better, but not exactly the same as the human eye.

Sometimes, we will reproduce a scene ideologically and subjectively, or reproduce the truth by means of superposition of several photos or manual adjustment later.

The more accurate the exposure, the clearer the photos will appear. If a part is overexposed or underexposed, the line outline of the object will be blurred. Therefore, some cameras will display the histogram of photo exposure, prompting whether the photo is overexposed or not.

Additional points: In order to achieve the best and clearest picture quality, accurate focusing is one thing. If the light conditions permit, the shooting is stable, and the lower the sensitivity, the better the image quality, such as ISO value 100.
