How to choose a digital movie camera

Mainly: CCD: The pixel of CCD is an important index to measure the imaging quality of digital camera, and the pixel size directly determines the clarity, color and fluency of the captured image. The pixel of CCD basically determines the grade of digital camera.

The pixel of CCD basically determines the grade of digital camera. At present, the middle and low grades are generally around 800,000 to 6.5438+0 million pixels, and the middle and high grades are generally above 6.5438+0.2 million to 2 million pixels. Pixel size directly determines the clarity, color and smoothness of the captured image. Number.

A camera usually comes with several accessories, such as charger, thin battery, AV cable, etc. Generally speaking, we need to buy at least one large-capacity battery, a camera bag and some adhesive tapes. You can choose these accessories according to your own situation.

The basic essentials of choosing a digital camera-choosing a machine to choose a nine-element digital camera are quite similar to traditional cameras in terms of optical and mechanical structure and electronic exposure control. The biggest difference between them lies in the difference of imaging medium and imaging principle. Digital camera is much more complicated than traditional camera in imaging and working principle.

We not only need to know the market situation and product information. More need to master and adhere to the following purchase principles. 1. Accurate positioning is the most critical. First of all, we should be clear about the purpose of buying digital cameras and our own economic situation. 1, Sony FDR-AXP35 Sony FDR-AXP35 positioning home camera, Gensonnie FDR-AXP35 not only has the characteristics of small size and convenient use, especially its software and hardware characteristics such as 4K video shooting, carl zeiss Vario-SonnarT lens and built-in projector.

2, Panasonic HC-VX9804k camera product introduction Panasonic's new HC-VX980 is a digital camera with 4k video recording and 4k camera mode. The machine is equipped with leicaDicomar lens, with 4K high-precision autofocus AF technology and 4K cutting function.

3. A better home computer is Sony FDR-AX 100E, but it is enough to have Sony FDR-AXP55 at home, and it is not necessary to spend about 10,000 yuan to buy an FDR-AX 100E.

4. Panasonic camera is good. The quality and performance of Panasonic 4K products are comparable at the same level. High-priced broadcast cameras have the best performance and quality. Panasonic is a traditional camera manufacturer with good product quality. Sony's 4K upgrade, Sony products have absolute advantages, and the same price must be better than Panasonic.

5. Recommended: Sony) PXW-FS7 professional digital movie camera FS7K (including FE28- 135), the price is about 70,000 yuan.

6. Sony FDR-AX30 can support 4K/25P video recording and can shoot for about 2 hours with original battery. In terms of other functions, it also supports WiFi and NFC connection, multi-camera joint shooting and night vision shooting. And it is worth mentioning that generally this level of camera does not have night vision shooting.

What camera do you use to make a movie?

The shooting of low-end movies is generally done by ARRI series machines, especially ALEXA of ARRI. The picture is really 8K, and it has a high tolerance, which has been recognized by many filmmakers. The mainstream movie cameras include Sony's F-35F-55F-65 and so on.

The most professional digital cinema machines are arri and RED. Now it is the mainstream equipment for making movies. But it must be equipped with a professional team. It's best to make a small noise at 5d2, and a few people are enough. Lightweight and easy to control, the picture quality has a strong film feeling, and there is no need for too much post-color matching.

Redo is more appropriate. 33mm frame, up to 4K resolution. At present, many micro-movies, TV movies and small investment feature films are shot with this lens.

If the camera shooting the back of the movie is a low-end movie shooting, ARRI series machines are widely used for shooting. In particular, ALEXA of ARRI has been recognized by many filmmakers for its high screen tolerance of 8 K.

How to choose a suitable cinema projector for a cinema?

There are many kinds of projectors used in cinemas, the most mainstream ones are: DLP projector, laser engineering projector or 2K &；; 3D projector Movie projector is different from projector in that it can project dynamic images onto the screen.

Brand: NEC second-and third-tier cities have the highest penetration rate, with two K Wang Zhongwang, affordable price, wide circulation of second-hand mobile phones, simple operation and acceptable quality. It is very cheap.

In the case of limited budget, you can choose Chinese giant screens or unilaterally distinctive cinemas (RealD, DTS: X, Honore, etc. ), but also uphold the principle of "good looking" over "good listening" in the selection. Because IMAX has a special camera, IMAX has great advantages in screen area and larger frame compared with ordinary cinemas.

Unlike projectors, movie projectors can project dynamic images onto the screen. The traditional film projector uses film, just like the projector uses film, except that the film projector can play 24 frames per second, making the original static image look dynamic.

At present, most cinemas are still movie projectors, and there are many new cinema digital projectors. The common projector you mentioned in school is a digital projector, but it is not the same as the projector. Its power is much higher and its brightness and resolution will be much higher.

The mainstream brands of 3K digital projectors include Sharp HAYING and vivitek DP. The mainstream of 3D system is XPAND active 3D Dolby 3D, which basically covers 90% cinemas. The spring of digital cameras is booming, and the film machine is already declining. The newly opened cinemas are basically digital machines. Give it to me.

How to choose a digital camera?

1, brand. In fact, in our daily life, the quality of electrical appliances of big brands must be speechless and recognized by consumers. Therefore, for young people who buy digital cameras for the first time, it is best to have a clear understanding of the quality, price and after-sales service of digital cameras of various brands.

2. Select parameters. According to the price, choose the one with better parameters in the same price. The most important parameters in choosing a digital camera are the size of the photosensitive element (CCD or CMOS) and the important parameters of the imaging quality. The bigger the better, the clearer the image. General consumer-grade DC is 1/6- 1/5 inch, and Quan Huafu SLR is 36× 24 mm

3. First, summarize the basic requirements of camera purchase. The most important thing is to determine the purpose of your digital camera purchase. If it is for daily use, taking photos of scenic spots or taking selfies, the general card machine is enough (in fact, the current mobile phones are basically competent). If you prefer landscape photos, you can choose a camera with telephoto function or a SLR.

4.★ Resolution can have multiple values. The higher the resolution provided by a digital camera, the more flexible it is to take and save photos. ★ The resolution of the picture is related to the imaging size and magnification at the time of output. The higher the resolution, the larger the imaging size and the higher the magnification. The total number of pixels in a digital camera refers to the total number of pixels contained in a CCD.

5. The specific method of choosing digital camera; First of all, the imaging quality of a digital camera should be selected from the imaging quality, which depends largely on the pixel level of the imaging wafer besides the lens quality.

Which 3D vision camera is cost-effective?

1, TeledyneDalsa, LMI and SICK are all good.
