How to shoot the best quality SLR?

1. The hardware that determines the quality of digital imaging is the image sensor, lens and image processor. As long as these three pieces of hardware are the same or basically the same, the picture quality is the same or basically the same. Didn't say that high-end SLR is better than entry-level SLR. The high-end SLR is high-end because it has a better and more advanced control system, which affects the success rate of shooting, commonly known as shooting or not;

2. When using the same shooting equipment, it is the illumination and lens parameter settings that determine the image quality;

3. Illuminance is the brightness of ambient light, which determines the sensitivity of digital cameras (including SLR). The better the light, the lower the available sensitivity and the better the imaging quality. The weaker the light, the higher the available sensitivity and the worse the image quality. In the environment with unsatisfactory illumination, light distribution (such as lighting) is needed to improve illumination to ensure image quality;

4. The same lens has different aperture, different aperture settings and different imaging quality; Under the same aperture setting of the same lens, the imaging resolution and imaging quality are different at different shooting distances. All lenses have their best aperture and best shooting distance (imaging or shooting distance);

5. The best aperture means that the resolution (or resolution, resolution) of the lens is the strongest when the lens is set with the best aperture value. Generally speaking, the best aperture of a lens is that the maximum aperture is reduced by 3-4 steps. For example, for a lens with a maximum aperture of F 1.4, the first aperture is F2, the second aperture is F2.8, the third aperture is F4, and the fourth aperture is F5.6, so F4 or F5.6 is the best aperture of the lens with the highest resolution. Except for the video lens, the maximum aperture of the video lens is the best aperture;

6. The best distance is the best shooting distance, when the resolution of the lens is the strongest. Generally, the calculation method of the best shooting distance is the lens focal length X 50 X (1-3), which can usually take the middle value, namely the focal length X 50 X 2. For example, a 50mm lens is 50 mm x 50 x (1-3) = 250 mm-750 mm = 2.5-7,5 m, and the median value is 5 m.

7. In the case of the best aperture and the best shooting distance, the picture quality of SLR is the best;

8, different aperture, different distance. It will affect the depth of field and perspective of the image, and the image quality is not the only standard in photography. How to choose, you need to choose according to different shooting themes, and make necessary compromises between perspective, depth of field and image quality.
