Shooting is really not as simple as just pressing the shutter
Indeed, photography was not as simple as pressing the shutter. As photography was a subject that combined technology and art, it required one to master a wide range of knowledge and skills. On the technical level, one had to be familiar with the use of photographic equipment, such as the different shooting modes of the camera. For example,"Aperture priority" was more commonly used to control the depth of field,"Shutter priority" was used to control the dynamic subject shooting, and manual gear was used when the focus could not be accurately focused. For mobile phone photography, one also needed to understand its basic functions. At the same time, the use of light was crucial. The light angle in the morning and evening was good and the light quality was soft. It was the ideal shooting light. During the shooting process, one also had to pay attention to the direction, angle, and the light effect of the subject. On the artistic level, composition was one of the key elements. One had to consider the layout of the main body, accompanying body, environment, prospect, background, and other elements. Diagonal composition, triangular composition, and so on were all commonly used composition methods. In addition, the use of contrast techniques could make the photo more vivid, such as color, light and shade, shape and other aspects of contrast. You could also find layers of scenery to create momentum, use the prospects to enhance the visual impact, and choose a suitable background to shoot silhouettes. These techniques required constant learning, practice, and accumulation of experience in order to take satisfactory photos. Read more exciting novels for free

What's the sound of pressing the shutter?
For a mechanical shutter camera, when the shutter was pressed, it would produce a "click" sound. This was because the mechanical shutter was usually composed of a front screen and a back screen. When the shutter button was pressed, the front screen quickly opened to start the exposure, and the back screen quickly closed to end the exposure. The sound of two metal pieces or cloth colliding or rubbing was the " click " sound. As for electronic shutter cameras, they used electronic signals to control the time when the light-sensitive element received light. There was usually no physical obstruction, so when the shutter button was pressed, there was no physical movement or collision. Under normal circumstances, no sound was produced. However, the click sound of the electronic shutter could also be added or canceled. When it was added, it mainly served as a reminder and feedback, such as letting the photographer and the person being photographed know that the photo had been taken. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Shutter priority shooting teaching video
The following is a tutorial video script on shutter priority shooting: Scene 1: Introduction to Shutter First Duration: 0:00 - 0:15 Scene Parting: Mid Scene Image: The cameraman was holding his camera and facing the camera. "Hello everyone, today we're going to learn the shutter priority shooting mode." Shutter priority means that the photographer can set the shutter speed himself. The camera's light measurement system will automatically select the appropriate aperture according to the light intensity of the scene to expose the camera correctly." Music/Sound Effects: Relaxed background music Filming location: indoor studio Shot 2: camera settings-enter shutter priority mode Duration: 0:15 - 0:35 Scene: Close-up Screen: camera operation, showing the camera mode dial to the TV or S position. Line: "First of all, we have to set the camera to shutter priority mode. Different camera brands may have different operations to enter this mode, but most of them are to turn the mode dial to the TV or S position." Music/Sound effects: The sound of the camera buttons. Filming location: indoor studio Scene 3: Confirm the key (exposure compensation) Duration: 0:35 - 1:00 Scene: Close-up Screen: camera operation, showing the dial to adjust the exposure compensation. If it was an entry-level camera with only one dial, you had to press the exposure compensation button and turn the dial to adjust. "After entering shutter priority mode, we have to first determine the tone of the photo, which is to adjust the exposure compensation. When shooting the same subject or scene, the tone is basically the same, so it's fine to adjust it once." Music/Sound effects: The sound of the camera buttons. Filming location: indoor studio Shot 4: Choose the shutter speed-Shoot a moving object Duration: 1:00 - 1:30 Scene Parting: Mid Scene Picture: Cut to the outdoors. There are children playing. The photographer adjusted the shutter speed according to the children's movement speed. When we want to shoot moving objects, such as children playing like this, in order to freeze their movements, we need a fast shutter speed. In this case, a shutter speed of 1/160 or above was more suitable. If it's a faster sport, such as athletes in sports events, you might need a shutter speed of more than 1/500 seconds or even more than 1/2000 seconds." [Music/Sound effects: outdoor environment sound, camera button operation sound] [Shooting location: outdoor playground] Scene 5: Inspection and adjustment of shooting effects Duration: 1:30 - 2:00 Scene: Close-up Image: The photographer looks at the photo taken on the camera display, then adjust the shutter speed again to take a new photo. Line: "After taking a picture or a group of pictures, we have to check the effect of the picture. If the desired effect is not achieved, we will continue to change the shutter speed and continue to test the picture until we are satisfied." Music/Sound effects: The sound of the camera buttons. [Shooting location: outdoor playground] Scene 6: Choose the shutter speed-slow door shooting Duration: 2:00 - 2:30 Scene Parting: Mid Scene [Scene: Cut to the street at night. The photographer adjusted the shutter speed to capture the trajectory of the car lights.] Line: "If we want to shoot a slow-motion effect like a car's headlights, we need to slow down the shutter speed. However, when using the slow door, due to the long time of light, you may need to use a tripod to keep the camera stable." [Music/Sound effects: Street environment at night, camera button operation sound] [Filming location: Night street] Scene 7: Slow Gate Tracking Technique Duration: 2:30 - 3:00 Scene Parting: Mid Scene [Image: In a sports scene, the photographer uses a slightly slower shutter speed (about 1/60 - 1/125 seconds), adjust the focus mode to artificial intelligence servo-focus, and track the athlete.] Line: "There is also a slow-motion tracking technique. When shooting high-speed objects such as sports competitions, you can set the shutter speed to about 1/60 - 1/125 seconds. You can choose the artificial intelligence servo-focus mode and use it with the main body tracking mobile camera. Then, you can shoot the main body clear and the background blurred. However, the shutter speed is too fast or too slow." [Music/Sound effects: Sports stadium environment sound, camera button operation sound] Filming Location: Sports Arena Scene 8: Summing Up Duration: 3:00 - 3:30 Scene Parting: Mid Scene Scene: The photographer is facing the camera again. Line: "This is the basic operation and some techniques of the shutter priority shooting mode. I hope everyone can practice more and take satisfactory photos."

Slow Shutter Shooting at a Scenic Spot
Slow-shutter photography of tourist attractions had many uses and effects. When shooting urban tourist attractions, the slow shutter could eliminate the interference of people. As long as the pedestrians were moving, they would become translucent under long exposure, thus accentuating the main landscape. When shooting tourist attractions like the Iceland Waterfall, the slow shutter speed could freeze the water flow, giving the water a silk-like texture, giving people a sense of tranquility and distance, while the normal shutter speed could record the majestic moment of the waterfall rushing down. In addition, when shooting tourist attractions such as auroras, which required pure and clear images under dark light, high sensitivity, and long exposure, a slow shutter with appropriate sensitivity settings could produce a picture with rich details, less noise, and purity even if it was 100% magnified. It was also best to have a bright future (such as buildings, rocks, people, etc.) when shooting auroras and stars, so that the picture would be more dynamic and artistic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Slow Shutter Shooting Skills School
Here are some techniques for shooting with a slow shutter speed: - ** Shooting parameters settings ** - ** Shutter Speed **: Generally 1 - 30 seconds, but it depends on the specific situation. For example, when shooting a moving object to produce a motion blur effect, shooting a running person may produce a blur effect in 1/30s, and shooting a walking person may require a shutter speed of more than 1/10s; When shooting a waterfall and other scenery to make the water fog and blur, a second or two of exposure can make the water soften and produce texture, and a longer exposure can completely soften the water. - ** Aperture **: F8 and above. Try to use a small aperture to get a deep panoramic view. - ** Light sensitivity **: Set it to 100 (minimum). - ** Shooting precautions ** - ** Stabilize the camera **: Use a tripod or a single tripod to stabilize the camera, because a slight shake of the camera at a slow shutter speed will affect the picture. Even without a tripod or other auxiliary equipment, he still needed to find a stable support. - ** Turn off the lens anti-shake **: This prevents the anti-shake function from interfering with slow shutter shots. - ** Reasonably Composed **: For example, the horizontal line composition, three-point line composition, and other common composition methods. - [Control of distance from the subject: For example, the closer you are to the water flow, the better. This way, the image will have more impact.] - ** Use of filter (light reduction mirror/ND filter)**: The light reduction mirror is used to reduce the amount of light entering the camera lens, helping to use a longer exposure time in bright environments. When using it, you must pay attention to the balance of exposure time. You can't just pursue long exposure and ignore other factors such as composition. - ** Special Shooting Techniques ** - ** Motion-Blur Effect **: When the shutter speed is slower than the moving speed of the subject, motion blur will appear. For example, when shooting people running or walking, the shutter speed can be adjusted according to the degree of blurring. - ** Focus Tracking **: A fixed camera can capture a clear picture of the main body with a blurred background when shooting a moving object; a pan camera can keep the moving main body in the same position in the picture, and can capture a relatively clear picture of the main body with a blurred background. - ** Double exposure (combination of slow shutter and flash)**: A photo with a slow shutter and flash. After pressing the shutter, the flash first froze the person. Under the continuous light, the camera continued to record. The camera shook slightly and a trail appeared. It could also be achieved by controlling the aperture to reduce the amount of light entering, using a slow shutter speed, holding a flash trigger, and pressing multiple times to freeze multiple people within two or three seconds of the camera shooting. - ** Speed (Portrait Shooting)**: Lower the shutter speed to 1/60 seconds and switch to manual focus mode. Plan the model's running route in advance and let the model stand at the best position to focus in advance. After the model took two steps back, when the model ran to the designated position, press the shutter and gently swing the camera in the running direction. - ** Elimination of interference (city scenery shooting)**: Use long exposure (an application of slow shutter) to "delete" the flow of people from the image. As long as the pedestrians are moving, they will become translucent, thereby emphasizing the main landscape. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Simple Video Shooting Techniques
Here are some simple video shooting techniques: - [Mirror Manipulation Technique: There are eight ways to move the mirror: push, pull, shake, shift, follow, spin, swing, and shake.] "Pushing" was to shoot the object from far to near;"Pulling" was to shoot from near to far;"Shaking" was to shoot up and down or left and right of the object;"Moving" was to shoot with the moving object;"Following" was to shoot while walking with the moving person or object;"Rotation" was to shoot a circle around the object clockwise or counterclockwise. Shaking and shaking these two lens movements were difficult for beginners to master, so they should not be used for now. - ** Create image effect **: - If you want to take a video with a solid front and a blurred front or a blurred front and a blurred back (take a mobile phone as an example), turn on the video mode of the mobile phone camera, select one or more times the focal length, and slowly approach the object you want to take a clear shot (such as a flower) until the object is clear and blurred in the distance (solid front and blurred back effect). Lock the focus on the object and start shooting. You can also perform a semi-surround lens. - In order to increase the fullness of the picture during shooting, some delay and transition effects can be used appropriately. - When shooting indoors, if the background is messy, you can adjust the aperture to make the background blurred. - ** Scene-related **: - ** In-room shooting **: Choose a house far away from the street and close the windows to reduce the noise from the outside world. The lighting settings should be set according to the light source as much as possible, and the shooting background should be kept clean and tidy. - ** Shooting outdoors **: Try to avoid taking photos while walking with your mobile phone. If you can't avoid it, you need to use a mobile phone stabiliser. If you are shooting sports scenes, you can use a pan/tilt stabiliser. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The difference between mechanical shutter and electronic shutter
A mechanical shutter was a device that relied on mechanical structures (such as springs, gears, and other components to drive the shutter curtain to open and close) to control the time when light entered. It first appeared in the era of film cameras. The electronic shutter relied on electronic signals to control exposure, which was achieved by directly turning on and off the image sensor. The difference between the two was as follows: 1. ** In terms of shooting experience **: The mechanical shutter will make a machine collision sound when shooting, while the electronic shutter will not make a sound when shooting (the click sound is simulated). Therefore, the mechanical shutter is not suitable for shooting scenes that need to be silent, such as conference speeches, wild animals, wedding ceremonies, theater performances, etc., while the electronic shutter is suitable for such scenes. 2. ** Jelly effect **: Mechanical shutters can effectively avoid the "jelly effect"(the image may be distorted when the electronic shutter shoots fast-moving objects), but the electronic shutter may cause the jelly effect when shooting high-speed objects. However, the global electronic shutter of some cameras may not have this problem. 3. ** Service life **: Mechanical shutters are mechanical devices and have a maximum number of uses (usually hundreds of thousands of times). Electronic shutters do not have mechanical moving parts, so there is no such problem. 4. ** Shutter speed **: Electronic shutters can have a higher shutter speed (some cameras can reach an electronic shutter speed of 1/32000 seconds), suitable for shooting fast-moving objects such as sports competitions or high-speed racing. Although mechanical shutter speeds can also meet the shooting of some moving objects (for example, a certain camera shutter speed can reach 1/16000 seconds), it is generally inferior to electronic shutters in terms of high-speed shutter speed. 5. ** In terms of vibration **: Since the electronic shutter does not have the movement of the shutter curtain, there is no shutter vibration. During long exposure or when using a super telephoto lens, it can reduce the blurriness caused by vibration. The mechanical shutter has shutter vibration. 6. ** Picture stripes **: Under the same parameters, some electronic shutter cameras may have stripes in artificial light scenes (for example, the electronic shutter image of the SonyFX30 under the LED light has zebra stripes). Mechanical shutters have fewer such problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
scanner shutter
The largest external size of the scanner shutter product was 121.80mm x 88.86mm x 25.77mm. The average thickness of the plastic part was 2.70mm. The plastic part was made of PC+ABS. The shrinking rate was 1.005. The mass of the plastic part was 18.35g. The technical requirements of the plastic part were that there should be no defects such as peaking, incomplete injection molding, flow lines, pores, warping, silver lines, cold material, spray lines, bubbles, etc. The plastic part in the product drawing was a complex support. Although it did not have a complex surface, its height fluctuated greatly. Its shape was complex and its shape was symmetrical. It played a functional support role in the product and was a key component inside the product. There are four vertical walls in the middle, each with a through hole of? 3.2. The four holes here must ensure the requirements of the degree of concentration to facilitate the flexible rotation of other related parts after assembly. The two ends of the U-shape had a hook to assemble other components. There was a hook at the bottom of the U-shape. All these installation parts required accurate size, so there were high requirements for geometric tolerance. The difficulty of the mold design was the choice of the mold opening direction, the design of the parting surface, and the design of the four-hole sliding block core-pulling mechanism. Due to the large size of the plastic part, the complex structure, the fluctuation of the parting surface, and the many rubbing positions, the mold was ranked first. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Electronic Shutter
Different cameras had different electronic shutter parameters. For example, the shutter speed of the Audi S2 - P was 32 - 1/4000 seconds, and the B-door could reach 120 seconds. The electronic shutter speed of Canon's Eos R3 could reach 1/64000 seconds. In terms of continuous shooting speed, the high-speed continuous shooting could reach up to 30 frames per second (electronic shutter), the high-speed continuous shooting could reach up to 15 frames per second (electronic shutter), and the low-speed continuous shooting could reach up to 3 frames per second. The electronic shutter (RAW) of the Nikon Z63 was 20 frames per second. Canon R7's electronic shutter could shoot more than 30 photos per second. In addition, the speed of the electronic shutter could also be affected by many factors, such as shutter speed, aperture value, aperture state during continuous shooting, flash shooting, anti-flicker shooting, battery type, battery level, temperature, use of built-in Wi-Fi, subject, lighting conditions (dark scene shooting, etc.), lens type, internal buffer full (temporarily unable to shoot) and other conditions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Shutter calculation
There were many ways to calculate the shutter: 1. ** Safety Shutter Calculation **: Generally, the safety shutter is calculated by the inverse of the focal length, which is 1/focal length. 2. ** Shutter calculation to avoid smearing **: Assuming the speed is <<v>>(m/s) and the cell size is <d>(mm), smearing will occur when the motion of the object is greater than 1.5 px during the shutter time. Otherwise, the shutter time <t> is less than or equal to <1.5d/v>(the unit must be unified, and the cell size is converted to m). 3. ** Shutter calculation after using the dimmer lens **: - One method was to know the deceleration factor of the ND lens. For example, the ND1000 was reduced by 10 gears, and the deceleration factor was 1000 times. Knowing the basic shutter speed of <t00>, the shutter speed after using the dimmer lens was <t = t00 ×>. For example, the basic shutter speed was 1/125 seconds, and the shutter speed after using the ND1000 was 1/125 seconds ×1000 = 8 seconds. - Another calculation method is: New shutter speed =(=) Base shutter speed × (2^{dimming gear}). For example, if the shutter speed is 1/125 seconds without the dimmer, then with the ND8 dimmer (dimming gear is 3), the shutter speed after using the dimmer = 1/125× (2^{3})=1/125×8 = 8/125 = 1/15 seconds. You can also use the shutter calculation tool for the ND lens, such as a mobile APP or an online calculator. Enter the basic shutter speed and the dimming intensity of the ND lens, and the tool will automatically calculate the shutter speed after using the ND lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
