Here are some ways to get started with DSLR photography: - ** Web application **: You can use Android applications such as the Knowledge and Techniques for Taking DSLR Cameras to learn DSLR basics. - ** Picture and Text Information **: Search for information related to the basics of DSLR on the Internet, such as the functions of the camera buttons, understanding the lens, understanding the parameters, and other introductory knowledge. - ** Video Materials **: Watch videos on platforms such as TikTok about DSLR photography techniques, introductory tutorial, and the difference between DSLR and micro-DSLR. Learn about DSLR operation knowledge, shooting techniques, and comparison with other photography equipment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some basic settings for a beginner camera: 1. ** Exposing settings ** - ** Aperture **: If you are shooting a portrait in a low-light environment and need to highlight the main body and blur the background, you can choose a larger aperture (such as a small f-value aperture such as f/1.8). If there is sufficient light and a large depth of field is required (such as shooting a landscape, you want the background and the background to be clear), choose a smaller aperture (such as a large f-value aperture such as f/16). - ** Shutter Speed **: When shooting fast-moving objects, choose a faster shutter speed (such as 1/1000 second) to freeze the motion. When shooting still objects or to create motion blur effects, choose a slower shutter speed (such as 1/2 second). However, a tripod may be needed to avoid blurring caused by camera shake at a slow shutter speed. - * * 2. ** Focus setting **: Cameras generally have two modes: autofocus (AFF) and manual focus (MT). For most beginners, autofocus mode was suitable for most shooting scenes. Single-point focus was suitable for shooting static objects, and the focus point could be manually selected. Continuous focus was suitable for shooting moving objects, and the camera would continuously adjust the focal length. 3. ** White balance setting **: The camera usually has an automatic white balance function, which is suitable for daily shooting. The camera will automatically adjust the color temperature according to the surrounding light, so that white objects still look white. If you are under a specific light source (such as sunset), you can also manually set the white balance to obtain the desired color tone. 4. ** Shooting Mode ** - ** P Mode **: This is a semi-automatic mode. The camera automatically sets the aperture and shutter speed according to the surrounding light. It is suitable for beginners. - Aperture priority mode (A or Av Mode): If you want to control the depth of field, you can choose this mode. In this mode, the photographer can manually set the aperture and the camera will automatically adjust the shutter speed. - ** Shutter priority mode (S or Tv Mode)**: It is suitable for shooting sports scenes. It allows the photographer to set the shutter speed and the camera will automatically adjust the aperture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were a few things to consider when purchasing a lens for photography: ** 1. Clear shooting requirements ** 1. ** Portrait Shooting ** - If the main shot was a portrait, a fixed-focus lens was a good choice. For example, the EF50mm F/1.8 lens was relatively cheap, known as the "small spittoon." It was small, light, and had good blurring effects, suitable for beginners/students. There were also 35mm, 85mm and other fixed-focus lenses that were often used for portrait photography. The 351.4 lens had a large aperture and good blurring effects. It was also suitable for small spaces (but more expensive). - The 55 - 250mm focal length of the telephoto lens was suitable for concerts, star-chasing scenes, and other scenes. It could also be used to shoot portraits, especially when the shooting distance needed to be zoomed in. 2. ** Scenery Shooting ** - The wide-angle lens was suitable for landscape photography, such as the focal length of 16 - 35mm (wide-angle lens). The focal length of 17 - 40mm lens was more suitable for taking landscape photos, street photos, environmental portraits, etc. However, the blurring effect was average, but it was very good for taking cultural scenery. - standard zoom lens (The focal length starts from 24mm or 28mm, and covers up to 70mm to 120mm medium telephoto lenses.) It can also be used for landscape shooting. For example, many cameras have a 18 - 55mm lens with a wide focal length. It can shoot scenery and portraits, but the quality is average, the aperture is small, and the blurring effect is not particularly good. However, it is enough if you only shoot scenery. The focal length of the 18 - 200mm lens was very wide. It was commonly known as "one lens can travel the world". It could shoot portraits and scenery without changing the lens back and forth. Moreover, the aperture was 3.5, and the blurring effect was not bad. 3. ** macro shot ** - The 100mm lens was very suitable for taking macro photos, such as flowers, still life, pets, and portraits. The blurring effect was especially good, and it was also suitable for shooting product drawings. ** 2. Understand the characteristics of the lens ** 1. ** Zooming and Fixed Focus ** - The focal length of the zoom lens could be adjusted and was easy to use. For example, the 18 - 200mm lens could cover a variety of focal lengths and was suitable for a variety of scenes. However, in terms of image quality, the effect of the fixed-focus lens was usually better. If you were pursuing higher image quality and unique imaging effects, you could consider the fixed-focus lens. 2. ** Anti shake function ** - The anti-shake function of the lens could not completely eliminate the shake, so you could not rely on the anti-shake function to choose the lens when you bought it. ** 3. Consider cost-performance ratio and budget ** - There was no need to pursue an expensive lens when getting started. For example, the Canon 18 - 55mm lens that came with many entry-level cameras was cheap. It was suitable for the initial learning of photography. First, master the basic shooting skills before considering upgrading the lens. At the same time, he also had to avoid blindly choosing expensive equipment because the imaging was not only related to the equipment, but also related to the creation and design of the photographer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
