Photographic single-lens reflex
In the field of DSLR, the situation was different. Usually, a camera with a resolution of more than 30 million was considered a high-resolution camera. The most popular range was between 24 million and 26 million. There were many DSLR cameras in this range. However, there were also higher-resolution DSLR cameras. For example, Canon's Eos 5D Mark IV DSLR camera used a new 30.4 million resolution sensor; the Nikon D810 had 36 million resolution; the Nikon D850 had 45.75 million resolution; and Canon had a Pixel-Emperor camera with 50.6 million resolution. At the same time, there were also DSLR cameras with relatively low resolution, such as some professional video cameras such as the Sony-A7S3, which had 12 million resolution. The quality of the image was not the only standard for measuring the image quality of an SLR camera. The image quality was also affected by the size of the sensor, the tolerance, and various parameters. Read more exciting novels for free
Single lens reflex photography
If it was about DSLR photography, the following were some of the key points for DSLR photography: ** 1. Selection of shooting mode ** 1. ** Portrait Shooting ** - **A (Aperture priority mode)**: suitable for portrait shooting. In this mode, the aperture size could be adjusted manually. A large aperture (such as f/1.8, f/2.8, etc.) could make the background blur, highlight the main body of the character, and obtain a natural blurring effect. It could also increase the amount of light in the case of insufficient light. - **M file (full manual mode)**: Can be used for portrait photography. The photographer had to manually set the sensitivity, aperture, shutter speed, white balance, exposure compensation, focus, color temperature, and other parameters. This mode was suitable for taking portraits under complex lighting conditions, such as indoor lighting or scenes that used specific lighting to create a special atmosphere. 2. ** Shooting of moving objects ** - **S (Shutter priority mode)**: Adjusts the shutter speed. The faster the shutter speed, the more it can freeze the instant image of a moving object. It is suitable for capturing people, animals, or sports events in motion. 3. ** Scenery Shooting ** - **M (Full Manual Mode)**: It is very useful when shooting scenes such as sunrise, sunset, night scene, sea of clouds, starry sky, etc. For landscape photography, you can manually adjust the sensitivity, aperture, shutter speed, and other parameters according to the desired effect. For example, when shooting the starry sky, high sensitivity, large aperture, and slow shutter speed were needed (generally, a tripod was needed to keep the camera stable); when shooting sunrise and sunset, the parameters had to be adjusted according to the light intensity and the desired color effect. ** 2. Shooting Points ** 1. ** In terms of composition ** - ** Find a unique subject **: Choose a good-looking or oddly-shaped subject. This kind of subject will be easily remembered by the audience. - ** Use geometric composition **: For example, a triangular composition can make the picture full of geometric beauty. When shooting a picture that contained multiple elements, the elements could be arranged and combined to form a triangle to increase the stability and beauty of the picture. 2. ** Focus ** - Portrait and animal photography: If you are shooting portraits or animals, pay attention to the light in your eyes. This will make the subject more vivid. For animal photography, you can use methods such as feeding to get the animal to cooperate so that the eyes of the subject have a bright reflection. 3. ** Picture level ** - When shooting a scene, you can increase the layering of the picture by changing the angle of view. For example, lowering the angle of view, using the front and back arrangement of the characters or the changes in reality to create a sense of hierarchy. ** 3. Later adjustments ** Most of the photos taken by the DSLR camera were original photos. They couldn't completely restore the scenery seen by the human eye, so they needed to be retouched later. He could use the phone APP to adjust the light, shadow, contrast, saturation, atmosphere, color temperature, clarity, and other parameters of the photo to adjust the photo to his liking. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Canon single-lens reflex character photography lens
There were many types of Canon DSLR lenses for character photography. Among them, the 35mm f1.4 lens had excellent performance in portrait shooting. It could capture the delicate expression of the character and show the surrounding environment. The f1.4 large aperture background blurring effect was good, suitable for traveling portraits or indoor portraits. The 85mm f1.2 medium-focus lens could capture the details and expressions of the characters while maintaining a certain distance on the full frame. The picture was natural and realistic. The f1.2 large aperture allowed it to take bright and clear photos in low-light environments. The blurring effect was better than that of the 35mm f1.4 lens. The 70 - 200mm f2.8 telephoto zoom lens had a flexible focal length range, and the background blurring effect was better than the 35mm and 85mm lenses. It was suitable for long-distance shots such as stage portraits, athletes, concerts, etc., but indoor shooting required a large space. The EF100mm F2.8L IS USM lens could be used for macro and portrait shooting. It had double IS optical image stabilization, good sharpness and out-of-focus performance, and ideal autofocus speed for macro shooting. The ESF135mm F2LIS USM lens was a close-up shot of a portrait. It could bring a stronger sense of compression and better blurring effect. The focusing speed was fast, the lens body weighed 750g, and the image quality was excellent when the aperture was fully opened. It was sharp inside the focus and soft outside the focus. The 50mm fixed-focus lens was also commonly used for portrait shooting. The F1.2 lens with a large aperture had a better portrait shooting effect. The 50mm focal length belonged to the standard focal length, and the shooting effect was close to what the human eye could see. It would not cause space compression and could better express the surrounding environment of the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to stack the lens of a single-lens reflex camera
The full name of the DSLR was " single-lens reflex viewfinder camera." It only had one mount. In theory, it could only be connected to one lens for optical imaging. Under normal circumstances, the lens could not be stacked. However, there were special uses, such as reversing the lens or connecting the zoom lens. However, these still needed to rely on a pure optical lens to use. On the basis of this lens, you could stack the transfer ring, zoom lens, etc. to achieve different effects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nikon old-fashioned single-lens reflex lens
Nikon's old-fashioned DSLR lens had many features. In terms of optical quality, some of the old lenses of Nikon DSLR had extremely high optical quality, such as the Nikon Nikkor 105mm f/2.5. Its design had been verified for a long time, and the lenses were polished and assembled carefully. Some of the materials used were more expensive than modern lenses, and special glasses such as thorium glass and lead glass, which were now no longer used, were used. This helped to provide a higher index of refraction, improve color difference control, and overall image quality. In terms of sharpness and color performance, it was not bad by today's standards. In terms of mechanical technology, the metal lens barrel and smooth focus ring of the old Nikon DSLR lens were different from the modern automatic lens made of plastic. It was more mechanical, and its texture, weight, and feel could give the photographer a retro film era feeling. In terms of adaptability, the old-fashioned lens of Nikon's DSLR could be perfectly combined with some current cameras, such as the Sony A7 series, the Fuji X-T series, and the Canon Eos R series. The electronic viewfinder of the mirrorless camera could enlarge the real-time view, making it easier to manually focus. Combined with the focus assist function, it greatly improved the experience of using it on digital cameras. However, for beginners, it was not recommended to use the old Nikon DSLR lens because the old lens had problems such as focusing stagnation and hesitation, although the accuracy was acceptable. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Image quality of a single-lens reflex telephoto lens

The RF100 - 400mm F5.6 - 8IS USM lens was light and sharp. The Canon EF50mm F1.8II had a F1.8 large aperture circle focal lens, which made the background blurred and beautiful. The Canon EF40mm F2.8ATM had advantages in workmanship, overall quality, and performance, and the picture quality was excellent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single-lens reflex camera with glasses
If you wore glasses and used a single-lens reflex camera to shoot, most single-lens reflex cameras had a refraction adjustment function. You can aim your eyes at the viewfinder, and after automatically focusing on an object, adjust the refraction adjustment button to the left or right until you see the clearest image. However, the position of the refraction adjustment button might be different for different brands of DSLR. It was usually next to the viewfinder. In addition, there were also photographers who said that they could see the viewfinder clearly with a single-lens reflex camera. If you feel that the image you see through the viewfinder is blurry, you can also consider putting on your glasses and shooting directly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Introduction to astrophotography single-lens reflex
The following are some of the key points for getting started with astrophotography: ** 1. Equipment Selection ** 1. ** Cameras ** - You can choose the manual mode of a DSLR camera or a mirrorless camera. Full-frame cameras had large sensors and were able to capture light in dark environments. They performed better, but the APS-C format camera was also suitable for astrophotography and was cheaper. 2. ** Shot ** - Wide-angle or ultra-wide-angle large-aperture lenses in the range of 12 - 35mm were suitable for Hoshino photography. Large-aperture lenses (with a maximum aperture of f/2.8 or above) were the best. For example, the Sanyang (Mori) 14mm f/2.8 lens was a good entry-level lens and was affordable. If you don't have a large aperture lens, you can also use the camera's attached lens to ensure that you can shoot at the maximum available aperture (generally, the lens is around f/4). ** 2. Selection of shooting location ** - Find a place without light pollution, such as a suburb with less light. Try to avoid taking photos in the city, because even the light pollution of a small town will affect the quality of the photos. It is difficult to take good photos in the city even during the full moon. You can consider camping to find a suitable shooting location. ** 3. Setting the camera parameters ** 1. ** Shooting Mode ** - He adjusted the camera to M (manual), which allowed him to fully control the various parameters of the camera. 2. ** Shutter Speed ** - The shutter speed was set to 15 - 30 seconds. 3. ** Aperture and sensitivity ** - Choose the lens 'maximum aperture and set the sensitivity to 3200. 4. ** Focus Mode ** - Set the camera to manual focus mode, turn the focus ring until the stars in the picture are in focus, and set a 2-second countdown to shoot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of a single-lens reflex camera
The following are some important settings for a DSLR camera: 1. ** Shooting Mode **: It is recommended to choose the manual mode (M). This way, you can control the shutter, aperture, sensitivity, and other parameters independently. 2. ** Video recording format and size **: If there are no special requirements, you can choose to record 1920*1080, 25 frames, MOV format of high-definition video. If there are special requirements for zooming in, you can choose 4K or other format. 3. ** Shutter Speed **: Generally, it is twice the frame rate of the video. For example, when the frame rate is 25 frames, the shutter speed is set to 50; when the frame rate is 60 frames, the shutter speed is set to 120. This way, the visual effect can be achieved. 4. ** Aperture **: The aperture size affects the depth of field of the picture. A large aperture (such as F2.8) made the picture brighter and the background blur stronger, while a small aperture (such as F11) made the picture darker and the background blur weaker. The larger the aperture value, the smaller the actual aperture. 5. ** Light sensitivity (USB)**: When there is sufficient light, the lower the USB, the better. It is not advisable to set it too high in a dark environment, otherwise it will produce noise. For example, Canon DSLR can be set to 100 during the day and 800 - 1000 at night. A high USB (greater than 2000) will produce obvious noise and it will be difficult to repair later. 6. ** Color temperature (white balance)**: adjust to manual mode. Generally, it is recommended to adjust the color temperature between 4900 and 5300. The higher the color temperature, the more yellow the screen will be, and the lower the color temperature, the more blue the screen will be. 7. ** Focus **: If you have good manual operation ability, you can try to manually focus and select the focus point. Novice or for convenience, you can use the automatic intelligent autofocus. However, it is recommended to practice manual focus more if possible. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
