Every time I take a photo, I look fat. How do I make someone look thinner?

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

Most of the lenses with anti-shake function currently on the market are composed of a gyroscope and a floating lens. The gyroscope detects shake and reminds the user to float. The lens makes corresponding reverse compensation, so that the purpose of anti-shake can be achieved.

When shooting with a tripod, when we press the shutter button, the reflector of the camera body rises, 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. However, because our camera is stationary when placed on a tripod, the quality of the photo is reduced. Therefore, when shooting with a tripod, we should turn off anti-shake and turn on the reflector lock-up function to ensure image quality.

2. The shutter speed is lower than the safe shutter

The safe shutter speed theoretically means: when we shoot, the shutter speed setting should be the reciprocal of the focal length of the lens we use. For example, when shooting with a 50mm fixed focus on a full-frame camera, the safe shutter speed is 1/50s. In other words, when shooting handheld, the shutter speed should not be lower than this value, otherwise the photos taken may be blurry. Here, we would like to remind non-full-frame camera users that the safety shutter of your camera should be multiplied by the equivalent factor 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 large aperture is everything

A large aperture can bring a charming shallow depth of field effect, but it is not everything. Many people are willing to spend a lot of money to buy a large aperture lens and believe that it is the solution to their photography problems. In fact, this is one of our common misunderstandings. For example, when shooting a portrait, use a large aperture (such as f/1.4), and if the focus is on the subject's eyes, it will easily cause the edges of the face to be blurred, and inexperienced photographers will not be able to use live view. , enlarge the screen and confirm the focus. In fact, large aperture is also relative. It is not called a large aperture only when the aperture is fully open. We beginners can use an aperture of f/5.6-8 more often, which will give the lens better image quality and sharpness, and increase the film yield.

4. Don’t dare to use high sensitivity

The increase in camera sensitivity is accompanied by an increase in photo noise. This is the most common sentence that new photography enthusiasts hear. Therefore, many people do not dare to risk increasing the sensitivity in order to ensure image quality. In fact, we need to consider the statement that increasing sensitivity will lead to a decrease in image quality based on the actual situation. With the improvement of production technology, the high-sensitivity performance of most digital products now, especially mid-to-high-end mirrorless and SLR cameras, is enough to satisfy our photography needs. For daily photography of enthusiasts, everyone needs to re-understand high sensitivity. Not all scenes can be completed using ISO100 in daily shooting. Raising the sensitivity will not only allow us to get a faster shutter speed, ensure the success rate of shooting, and get more exposure, but also use software for noise reduction in the later stage to better ensure the quality of our photos. .

5. Take pictures in a hurry while walking

In many cases, due to the rush of time, many people press the shutter before they even stand firm, so photography becomes A mechanical and hasty task, without giving more thought to the content that the photo needs to express. Respect for images and thinking about photography are what we need to learn and experience on the road to photography. Take every scene seriously and spend enough time observing and thinking. This kind of shooting practice is what most beginners need. It’s important to take more shots, and it’s necessary to take precise shots.

6. Over-sharpening

Sharpening is an important step in post-processing. This step can make our photos clearer. But as the pixels of the digital cameras in our hands increase, sharpening requires special attention. Over-sharpening can make photos look harsh and lack intimacy. Therefore, when performing post-sharpening processing, it is recommended that you do not set the sharpening value too high, especially when processing portraits.

7. Resize the photo after sharpening

Sharpening should be placed in the last step of the entire post-processing. It is recommended to adjust parameters such as contrast, brightness, and curves before this.

8. Misunderstanding of color space

Color space is also called color gamut, which can actually be understood as the range and richness of colors. According to the color range from large to small, they are arranged as ProPhotoRGB, AdobeRGB, and sRGB. We should choose the correct color space based on the output requirements of the photo. It is incorrect to use sRGB regardless of the purpose of the photo. Color space is actually related to the purpose of the photo. In normal web browsing, basically only sRGB can be displayed. When outputting large-scale works, it is recommended to use AdobeRGB instead, so as to obtain richer color details.

9. Don’t take exposure compensation seriously

Looking at digital cameras of different levels, the exposure compensation function is Being specifically set as a camera option shows the importance of exposure compensation. This is a very important parameter, especially in aperture priority mode.

For example, when shooting snow scenes in winter, we should increase the exposure compensation accordingly. This is because the camera usually measures snow based on 18% gray. In fact, snow is brighter than 18% gray. If we do not manually increase the exposure compensation, If you use exposure compensation, the snow scene you photograph is likely to be gray and gray, without the texture and color that white snow should have. On the contrary, if we want to shoot a dark object, we need to reduce the exposure compensation to ensure the correct exposure. This is what we usually call the "white plus black minus" principle.

10. Not checking the camera parameter settings before shooting

Some photographers develop bad shooting habits when shooting, that is, they put the camera directly after finishing the day's shooting. Shut down the camera and do not restore the camera parameters to the default state. When shooting the next day, we directly use yesterday’s parameters to shoot. Due to the different shooting objects and shooting environments, we usually take photos with problematic exposure. This not only You will waste time and miss many wonderful moments. Details determine success or failure. If you want to improve your photography skills, start with these little things.
