How to take DSLR pictures with the best quality?

1. The hardware that determines the quality of digital imaging is the image sensor, lens and image processor. As long as these three hardware are the same or basically the same, the image quality will be the same or basically the same. There is no such thing as a high-end SLR. The picture quality is better than entry-level SLR. The reason why high-end SLRs are high-end is because they have better and more advanced control systems, which affects the shooting success rate, commonly known as whether you can take a picture or not;

2. When using the same shooting equipment, decide Image quality depends on illumination and lens parameter settings;

3. Illuminance is the brightness of ambient light, and illumination determines the sensitivity of digital cameras (including SLRs). The better the light, the lower the available sensitivity, and the better the image quality; the weaker the light, the higher the available sensitivity, and the worse the image quality. In an environment where the illumination is not ideal, lighting (such as lighting, etc.) is required to increase the illumination to ensure image quality;

4. The same lens has different apertures, different aperture settings, and different image quality ; The same lens under the same aperture setting, different shooting distances have different imaging resolutions, and the imaging quality is also different. All lenses have their best aperture and best shooting distance (imaging or shooting distance);

5. The best aperture means that when the lens is set to the best aperture value, the lens has the strongest resolution ( Or called resolution, analytical power). Normally, the best aperture of a lens is the aperture value that is 3-4 stops smaller than the maximum aperture. For example, for a lens with a maximum aperture of F1.4, the first stop is F2, the second stop is F2.8, and the third stop is F2.8. It is F4, and four stops down is F5.6, so F4 ??or F5.6 is the best aperture of this lens and has the highest resolution. The exception is the video lens. The maximum aperture of the video lens is the best aperture;

6. The best distance is the best shooting distance. At this distance, the lens has the strongest resolution. Generally, the best shooting distance is calculated. The method is lens focal length X 50 X (1-3), usually the middle value can be taken, that is, focal length X 50 For example, a 50mm lens is 50mm

7. Under the best aperture and best shooting distance, SLR pictures have the best quality;

8. Different apertures and different shooting distances. It will affect the depth of field and perspective of the image. Image quality is not the only criterion in photography. How to choose, you need to choose according to different shooting themes, and make necessary compromises between angle of view, depth of field, and image quality.
