Do you know the basic knowledge that you must know to learn SLR-using tripod to avoid hand shock blur?

For beginners of photography, it is necessary to know that although it is a lens, the imaging effect of different apertures is different. Usually, the image quality of the maximum aperture and the minimum aperture is often poor. The optimal aperture of a lens is generally two-stage optimal aperture contraction. Many friends think that only expensive lenses can get excellent imaging. In fact, in many ordinary lenses, as long as you give full play to its advantages, you can also get the best picture quality.

There are several ways to get the best image quality:

1. Use the best aperture. This is the most direct and effective way to reduce the quality of professional lenses and ordinary lenses.

Use a tripod. Only by ensuring a clear picture can we ensure excellent picture quality. When the tripod does not need to be completely pulled out, pull out three legs first, and then pull out the center column if the height is not enough. When the tripod does not need to be completely pulled out, pull out the thicker part first, and then pull out the thinner part in turn if the height is not enough, so as to ensure the stability of the tripod to the maximum extent. Some feet have spikes at their lower ends. In soft places, unscrewing the foot nails can also play a role in grasping the ground.

3. Use lower sensitivity. Increasing the sensitivity will increase the noise of the picture, thus reducing the image quality. Even if it is lower than ISO400, the noise gap is small, but there is still a gap.

4. If possible, shoot as close to the object as possible. The closer you get to the topic, the more details you can get. The lens is like a human eye. The closer you get, the clearer you can see.

5. Take photos in RAW format. It may cost a lot of money to replace ordinary lenses with professional lenses. If the RAW format is not used, the difference in image quality loss will be even greater. Some people may think that using RAW is too troublesome, and JPEG is more convenient. If you just record your life, JPEG can meet it; If you want to create or do better post-processing, you should choose the RAW format.

These methods are always limited by different conditions, and must be analyzed in detail to get the best picture quality.
