The following are the main points related to photography and filming of the annual meeting: ** 1. Initial preparations ** 1. ** Clear shooting format ** - It was necessary to determine whether the event scene needed traditional styling photos or news reports. This would help the photographer prepare the camera model according to the specific needs, find the right time, angle, personnel, number of photos, and so on. 2. ** Confirm the number of people ** - The organizer should determine the number of photographers and videographers needed according to the scale and nature of the event, and make it clear whether only photography or video recording was needed, or both, as well as whether the camera position was fixed or mobile, so as to arrange the equipment. 3. ** Understand Professional Level ** - Before hiring photographers and videographers, the organizers could ask them to provide case studies of past events to understand their professional level and on-site adaptability. 4. ** Photographer preparing for work ** - In terms of equipment, if a single-lens reflex camera was used, the choice of lens had to be based on the actual situation. For example, 18 - 55 and 18 - 135 (C-frame lens), 24 - 70 and 24 - 105 (full-frame lens) and other common lenses, the better the quality of the lens was, the better the quality of the lens. If necessary, add a telephoto lens such as 70 - 200. If there are special needs (small venues or large scenes with more than 100 people), prepare a wide-angle lens. It is not recommended to use wide-angle for group photos. You can use a full-frame zoom lens with a 50mm focal length or a C-frame lens with a 35mm focal length. You can also choose a 50mm fixed-focus lens. An external flash was necessary because the light from the ceiling lamp in the room could cause uneven light to be received by the face. - Before the meeting, you must first take an aerial shot. Arrive at the scene in advance and turn on all the light sources to take pictures of the conference group's layout (such as banners, slogans, etc.). Communicate with the conference management staff in advance to understand the conference process and the day's activities. Plan the location of the group photo in advance, understand the number of people, and arrange the time. Tune the machine, check the equipment functions, set the relevant parameters (such as light measurement, color temperature, white balance offset, etc.), set the camera to continuous shooting mode, and open the dual format to save photos. ** 2. Filming process ** 1. ** Before the meeting starts ** - Get the agenda of the meeting, summarize and sort out the key shooting points (such as the leader's speech time, signing ceremony, etc.), arrive at the venue at least half an hour in advance, check the lighting position, test shoot, and choose the camera position, lens, and parameters. 2. ** Meeting in progress ** - ** Check in segment **: Record the people who check in and punch in, take pictures of the check-in scene from multiple angles, and quickly take pictures of important leaders, mainly in mid-shot and close-up. - ** Leader's Entrance **: After signing in, quickly find a suitable position and shoot the entrance scene according to the leader's entrance angle. Focus on the middle and long shots, and place the leader in the middle of the scene. - ** Leader's speech or seating **: If the leader is speaking on the stage or entering the venue to take a seat, take a panoramic shot, a mid-shot, a close-up shot, and take multiple shots to facilitate the selection of suitable photos later. - ** Close-up shot **: Close-up shots are the highlight. When shooting close-up shots of leaders and other people, you have to choose whether to use the flash according to the distance. For close-up shooting, the flash can be adjusted to a high angle to shine on the ceiling to reflect the light; for telephoto shooting, the flash can be directly aimed at the object; if the camera is advanced, the image sensor has high resolution and the light is good, the flash can be turned on and the USB can be adjusted appropriately (such as 400 - 800); if the flash cannot be turned on and the camera equipment is not good, a tripod can be used to assist. At the same time, if the camera has a red-eye reduction function, turn it on. - ** Shooting at the conference venue **: Choose a position where you can see the entire scene. Use a wide-angle lens to shoot. The light measurement should be measured from the middle and both sides should be taken into account. It is generally not recommended to use a flash. If you use a flash, it will cause the face of the person nearby to be too white and the person in the distance to be dark. If you want to use a flash, you can use a tripod and extend the exposure time appropriately. - ** Dynamic Picture Shooting **: When taking dynamic pictures such as awards or shaking hands, use the flash to increase the shutter speed and expose the correct exposure. Shooting with a flash at close range is similar to close-up shots. If you can't adjust the angle with the built-in flash, you need to step back a little to avoid white faces. If there is light on the scene and you don't need the flash, you can use a tripod to shoot. - ** Other Points **: Be bold and take more shots, but don't always shoot at the leader. Continuous shots are essential. Replay at any time to check if there are missed shots and make up for them in time. Pay attention to the reasonable use of shooting angles (panoramic, mid shot, close-up, and close-up). The panoramic view shows the environment, the mid shot can show the audience's reaction, and the flawed pictures (such as yawning, playing with the phone, dozing off) are recommended to be deleted. The aperture is prioritized with the appropriate sensitivity to ensure that the clarity and brightness are appropriate. After the shooting material is complete, the wonderful moments are captured. 3. ** Key Points for Leader Shot ** - The shots of important leaders should be more prominent than the shots of other leaders (such as a single close-up, the length of the shot, the angle of shooting, etc.); The shots of leaders should be taken at the right time, and the shots should be taken when the leaders look the best (such as when they make gestures in their speeches); When a long row of leaders takes the whole row of shots, they should be divided into two and a half rows of shots from the middle to the left and right; The shots of the conference host should not be more prominent than the shots of important leaders; The shots of local leaders should be taken carefully, not only the higher-ups.

从化学原理角度看,铁粉与稀硝酸反应主要涉及硝酸的氧化性以及铁的还原性。在常温常压下即可发生反应。 1. 当稀硝酸过量时: - 反应方程式为\(Fe + 4HNO_{3}=Fe(NO_{3})_{3}+NO↑ + 2H_{2}O\)。 - 这里硝酸体现强氧化性,将铁氧化为\(Fe^{3 + }\),硝酸中的氮元素从\( + 5\)价被还原为\( + 2\)价的\(NO\)。 2. 当铁粉过量时: - 反应方程式为\(3Fe+8HNO_{3}(稀)=3Fe(NO_{3})_{2}+2NO↑ + 4H_{2}O\)。 - 过量的铁会与生成的\(Fe^{3 + }\)进一步反应,将\(Fe^{3 + }\)还原为\(Fe^{2 + }\),最终产物为硝酸亚铁。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>
