How do students majoring in photography choose cameras?

Students majoring in photography can choose a camera according to its performance, cost performance, pixel resolution and still image shooting ability. Before buying a camera, you can go to a physical store to find out, shop around, or check online to see if there is a camera that suits you and buy what you need.

Camera performance

The performance of a camera is very important, and it can also be related to whether it can meet the needs of consumers. As a photography major, you can choose a simple camera at first. A camera with complex performance is difficult to use, and sometimes it can't keep up with the teacher's teaching progress. At first, you can buy an ordinary SLR camera to meet the teaching requirements of teachers. It is usually easy to use and does not need too many complicated functions.

Camera cost performance

Students who have just entered the camera major should consider the price of the camera to see whether it is worth the money, whether it is worth buying, whether it is the financial ability of the students or the support of their families. They can choose a higher-priced camera, the price is within their tolerance, and there is no need to pursue too high a price. After all, they just learned to use the camera, so as not to be hurt by improper use. In the future, they can choose a camera with higher price and more functions to improve their economic ability.

Camera pixel resolution

Whether a camera is worth buying or not, its pixel resolution is very important to us. But high pixel resolution does not necessarily mean excellent shooting quality, because the shooting quality of a camera depends not only on the quality of the image sensor, but also on the quality of our camera lens and the equipped focusing system. Therefore, the higher the camera image sensor and pixel index, the better the camera will be.

As a student majoring in photography, it is very important to choose a suitable camera. To sum up, we mainly look at three points: the pixel resolution of the camera, the focal length and aperture of the lens and the shooting ability of still images. The performance of the camera that meets these three points is quite good and can meet our basic needs.

How to choose a video conference camera?

The camera has many interfaces, such as USB2.0, USB3.0, DVI, HDMI and SDI. It mainly depends on what equipment you connect, and the interface needs to match.

The camera has fixed focus, 3 times zoom, 10 times zoom, 12 times zoom, 20 times zoom and so on. , must be equipped according to the site conditions;

Oni is recommended for conference cameras, and they also provide omni-directional microphones, hoping to help you!

What brand of camera should I choose to record the course? What are the precautions?

Many training institutions need to record the contents of teachers' lectures, one is to show them to distance education students, and the other is to keep a backup. A camera is needed at this time, so what brand of camera should I choose to record the course?

The camera of a training institution usually takes a long time to record, and it can be equipped with an external microphone or recording socket. Post-production is relatively simple, and most of them are made indoors. Bian Xiao, a dot matrix manufacturer, recommended Sony cameras, such as CX700, CX560, CX550, JVCHM880, HM890, HM990, HM970 and HM855, which are all high-end models with good low-light performance and wide angle.

Notes after recording the process with a video camera

1. The video recorder should be kept by special personnel to protect the lens when not in use; Close the lens cover (there is a pick next to the lens) and don't dirty or scratch the lens.

2. The location of the video is probably in the middle row of the classroom, on the side of the backlight, which ensures that the image can be clearly recorded and the scene of interaction between students and teachers can be photographed. The camera should not be too far away from the teacher, otherwise it will affect the input of sound. The camera should move flexibly with the teacher or students, but try not to have sudden changes in the picture.

3. When recording outdoors, be sure to choose windless weather to avoid noisy sound.

4. After recording the class, browse it yourself first. If there are major mistakes, please re-record (such as no sound, noisy sound or irrelevant to class, distorted picture, serious picture jitter, etc.). ).

5. After recording the video, import it into the computer in time. It is suggested to use format factory or storm transcoding to convert the video into MPEG format or MP4 format. If the video is divided into two segments, it must be merged into one segment by software. Interns can simply beautify videos by using audio and video software.

The above is the relevant content of camera brand and the matters needing attention in the recording process for everyone. When you buy a camera, you can buy it on e-commerce platforms such as JD.COM and Taobao. The price is generally around 5000, which is cheaper than the physical store. For training institutions that have just started, you can buy second-hand equipment!

Sony camera 198P__ 19500

This machine is an upgraded model of DSRPD190 P. As we all know, DSR-PD 190P has been favored by users for its excellent performance and good cost performance. As an upgraded product, DSR-PD 198P not only inherits many powerful performances of DSR-PD 190P, but also has many new improvements in lens, audio-visual quality and operational performance, and its performance is even better.

DSR-PD 198P adopts Sony's unique high-performance G lens, 36.1wide angle (equivalent to 4:3 35mm focal plane) and 20x optical zoom. It can meet the shooting angle of various shooting occasions, from the vast wild scenery to the local close-up that is difficult to get close-up, which can be easily realized. In addition, the G lens has independent zoom, focus and aperture control loops. This professional three-ring independent design is the first case in a small DVCAM handheld camcorder, and there are two ED (Very Low Scattering) lenses in the lens, which can reduce the chromatic aberration caused by the difference of light refraction and minimize the degree of color scattering. The advanced triple compound spherical mirror with 10 group and 15 lens structure will have the same clear picture in Ming Rui even under the condition of high zoom ratio.

As for the imager, DSR-PD 190P is different from DSR-PD 198P. It uses the high-end CMOS imager developed by Sony and the "Exmor" image processor developed by Sony. "Exmor" image processor is a component used in Sony's high-end camera. The processor adopts double denoising technology to effectively suppress and reduce noise and obtain high-quality digital signals, so that DSR-PD 198P can achieve the low illumination performance of 1.5_ux.

In terms of recording format, DSR-PD 198P still adopts DVCAM and DV(SP) recording modes, providing users with two choices. In addition, DSR-PD 198P not only provides interlaced scanning mode, but also provides 25P progressive scanning mode, which can record progressive signals by interlaced recording. It provides convenience for customers who need to shoot progressive signals. In addition, _SR-PD 198P also provides smooth slow-motion recording, shooting conversion function, assignment function and other functions, which provides more shooting methods and convenience for customers in the shooting process.

As a quasi-professional digital camera, Sony DSR-PD 198P has a high-performance G-class lens and a CMSO photosensitive element with higher quality and sensitivity. Excellent image capture ability makes the image clearer and more vivid. It is an image product targeted at DV lovers and small production companies.
