Photography up recommendation

1. Turn on the anti-shake function when using tripod.

At present, the lenses with anti-shake function on the market are mostly composed of gyroscopes and floating lenses. Gyroscope detects jitter and reminds the floating lens to make corresponding reverse compensation to achieve the purpose of anti-shake.

When shooting with a tripod, we press the shutter button, the reflector of the fuselage lifts and the shutter opens and closes. These high-frequency vibrations will be detected by the lens. If the anti-shake system is still working at this time, the floating lens will move accordingly to change the optical axis, but because our camera is still on the tripod, the quality of taking pictures will be reduced. Therefore, when shooting with a tripod, it is necessary to turn off the anti-shake and turn on the pre-lift function of the reflector to ensure the image quality.

2. The shutter speed is lower than the safety shutter.

Safe shutter speed theoretically means that when we shoot, the shutter speed should be set to the reciprocal of the focal length of the lens we use. For example, when shooting with a 50mm fixed-focus camera, the safe shutter speed is 1/50s. In other words, the shutter speed should not be lower than this value when shooting by hand, otherwise the photos taken may be blurred. In particular, users of non-full-frame cameras should be reminded that the safety shutter of your camera should be multiplied by the equivalent coefficient of the lens. In addition, the safety shutter is not suitable for shooting moving objects. If it is a high-speed moving object such as a car, it is recommended to use a higher speed.

3. A big aperture is everything.

Large aperture can bring charming shallow depth of field effect, but not everything. Many people are willing to spend a lot of money to buy large aperture lenses, which I believe is a good way to solve their own photography problems. In fact, this is one of our common misunderstandings. For example, when taking portraits, use a large aperture (such as f/ 1.4). If the focus is on the eyes of the subject, it is easy to blur the edge of the face. Inexperienced photographers will not enlarge the screen and confirm the focus through real scenes. In fact, the large aperture is relative, not only the full aperture is called the large aperture. We beginners can use f/5.6-8 aperture more, so that we can get better imaging quality and lens clarity and increase more output rate.

4. Dare not use high sensitivity

The improvement of camera sensitivity is accompanied by the increase of photo noise. This is a sentence that beginners of photography often hear. So in order to ensure the image quality, many people dare not take risks to improve the sensitivity. In fact, we need to consider the statement that improving sensitivity will lead to poor image quality in combination with the actual situation. With the improvement of production technology, the high-sensitivity performance of most digital products, especially high-end reflective and SLR cameras, has been enough to meet the daily shooting of our photographers. At this time, we need to re-recognize high sensitivity. Not all daily shooting scenes can be completed with ISO 100. Improving the sensitivity can not only make us get faster shutter speed, ensure the success rate of shooting and get more exposure, but also ensure the quality of our photos better by using software to reduce noise later.

5. Shoot in a hurry while walking

Many times, due to the rush of time, many people even pressed the shutter before they got a firm foothold, so photography became a mechanical and hasty job, without paying more attention to the content that photos need to express. Respect for images and thinking about photography are what we need to learn and experience on the road of photography. Take every scene seriously and spend enough time observing and thinking. This kind of shooting practice is what most beginners need. It is important to shoot more, and it is also necessary to shoot more.

Excessive sharpening

Sharpening is an important part of post-processing, which can make our photos clearer. But with the improvement of digital camera pixels in our hands, sharpening needs special attention. Excessive sharpening will make photos look stiff and lack intimacy. Therefore, it is recommended that you don't set the sharpening value too large when you do post-sharpening, especially when dealing with portraits.

7. Adjust the photo size after sharpening.

Sharpening should be placed in the last step of the whole post-processing, and it is suggested to adjust the parameters such as contrast, brightness and curve before this.

8. Misunderstanding of color space

Color space, also known as color gamut, can actually be understood as color range and richness. According to the color range from large to small, they are ProPhotoRGB, AdobeRGB and sRGB. We should choose the correct color space according to the output demand of photos, and choose sRGB regardless of the use of photos, which is not correct. Color space is actually related to the use of photos. In the usual network browsing, basically only sRGB can be displayed. It is suggested to switch to AdobeRGB when outputting large-scale works to obtain richer color details.

9. Don't take exposure compensation seriously.

Looking at different levels of digital cameras, the exposure compensation function is specially set as the camera option, which shows the importance of exposure compensation, which is a very important parameter, especially in aperture priority mode. For example, when shooting snow scenes in winter, exposure compensation should be increased accordingly. This is because cameras usually measure snow with the gray scale of 18%, but in fact snow is brighter than the gray scale of 18%. If you don't manually increase the exposure compensation, the photographed snow scene is likely to be gray, without the texture and color that snow should have. On the contrary, if you want to shoot dark objects, you need to reduce the exposure compensation, so as to ensure correct exposure. This is what we usually call the "white plus black minus" principle.

10. Don't check the camera parameter settings before shooting.

Some photographers have developed a bad habit of shooting, that is, turning off the camera directly after one day's shooting without restoring the camera parameters to the default state, and shooting directly with yesterday's parameters the next day. Because of the different subjects and shooting environment, we usually take photos with exposure problems, which not only wastes time, but also misses many wonderful moments. Details determine success or failure. If you want to improve your photography skills, start with these little things.
