1 The right camera For nighttime photography, the following cameras are more suitable? > can take RAW format-to improve image quality, improve noise and so on. > can be manually exposed – let you take a slow shutter, or push ISO with a high-speed shutter, depending on the situation > can be manually focused-sometimes too dark, manual focus is more convenient > Good low Light performance – the highest I

Transferred from: Http://ask.zol.com.cn/q/21060.html It is not important to have the body anti-shake function, as long as the camera has the anti-shake function. It is also important to have a good camera with a large aperture. One mirror is the easiest choice for beginners. After a long time, you will definitely change the lens, but the cost will increase. When purchasing a camera, I suggest you buy a wide-angle lens with a large aperture in one step. In addition, when purchasing a camera, the

reference value to those who are still exploring their experiences. These stupid tricks are: Multi-beat Selection"Multi-shot" means Multi-practices and accumulated experience in a macro sense. Specifically, you may wish to try multiple shots to win more, select more, or repeat a specific scenario after discovering the optimal solution. This is a clumsy trick, but it is indeed a trick to give full play to the advantages of digital cameras. it is not legal to take optical photo albums. You see, a

, produces a wide range of clear focusing ranges. Conversely, a large aperture (represented by a smaller F/value), such as f/2.8 or F/4, produces a short depth of depth, the acceptable clear range of prospects and backgrounds is much smaller. The choice of aperture is a basic element for creating a file instead of simply taking a photo. Even when using the program exposure mode, you should select the most appropriate combination of aperture and speed when feasible. However, it should be noted th

motion smoother and the scenes more realistic. More details Let's take a look at how the movie camera shot mobile scenes. A movie camera consists of the following parts: LensFocus light on film ShutterShutter control within a certain period of time, open to let the light. FilmThe film includes photosensitive chemicals. These photosensitive materials are used to record scenes and generate images. The picture on the left shows the situation when a still red sphere is take

Single AF (one shot) is the most common. The working process of this mode is initiated by a half-press of the shutter, and the focus process continues until the focus is not accurate. Once the processor considers the focus to be accurate, it completes the shooting process as soon as the shutter is completely pressed, while the AF system stops working. The focus is automatically locked after the focus is f

not very stable. So before the dip and offset, you can use the aperture first automatic exposure mode for metering, and then in manual exposure mode set the camera to calculate the aperture and shutter speed, and then make the necessary fine-tuning then shoot, so that the final photo brightness will be more stable. 3. Use offset compensation the lower width of the building is narrow First you have to make sure that the camera is facing the

The electromagnetic buzzer consists of an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm, and a shell. After the power is switched on, the audio signal current generated by the oscillator passes through the electromagnetic coil to generate a magnetic field. The vibration diaphragm periodic

A. What is EXIFExif (exchangeable image file) is an image file format that has exactly the same data storage as the JPEG format. In fact, the EXIF format is a digital photo inserted in the header of the JPEG format. Including the aperture, shutter, white balance, ISO, focal length, date and time, and other shooting conditions as well as camera brand, model, color coding, recording sound and the Global Positioning System (GPS), thumbnails and so on.

At the same time, the JVC also raised the long axis of the speaker diaphragm to make the sound field as if it had been diffuse from the entire screen, so that the sound quality at the front of the TV can be optimized.
