Auto bracketing
Bracketing is called shooting a series of frames, in which in each next frame the shooting parameters (exposure, white balance, focus, etc.) change by a certain amount. This allows, for example, to choose the most successful shot from several options, or to determine the effect of changing the settings in one direction or another. Auto bracketing allows you to take such shots automatically. At the same time, it should be taken into account that the set of parameters changed in the process may differ in different camera models. For example, some devices are able to change only the exposure, others — the exposure and/or white balance, etc.
File recording formats
File formats in which the camera can record video. Given that the footage is designed to be viewed on an external screen, you should make sure that the playback device (DVD player, media centre, etc.) is able to work with the appropriate formats. At the same time, many camera models themselves can play the role of a player by connecting to a TV via an audio / video output or HDMI (see the corresponding paragraphs of the glossary). And if the video materials are to be viewed on a computer, you should not pay special attention to this parameter at all: problems with format incompatibility in such cases rarely occur, but are usually solved by installing the appropriate codec.
Frame coverage
The ratio, expressed as a percentage, between the portion of the image that the photographer sees in the viewfinder (see above) and the image that is actually captured by the camera when shooting. Most often, it is specified as a percentage of the width and height of the frame, rather than the area.
Modern digital cameras often have viewfinders with a frame coverage of less than 100% - thus, the frame includes not only the visible scene, but also some space beyond its edges. This creates some inconveniences - in particular, it may be necessary to crop the photo to ensure a pre-conceived composition. Therefore, a viewfinder with 100% coverage is still considered the ideal option. Some time ago, such systems were found mainly in premium cameras, but now, thanks to cheaper prices and technological developments, they can be installed even in relatively inexpensive amateur compacts (see "Product type").
Communications
-
GPS module. The camera has a built-in GPS satellite navigation module. In digital cameras, the GPS module is used primarily for setting the so-called. geo-tagging to photos: information about specific geographical coordinates of the shooting location is recorded in the service information about each image. However, the matter is not limited to this, and models with this function can have many additional features - from classic navigation to special programs like a database of points of interest with hints based on the current location.
-
WiFi. A wireless standard originally developed for computer networking, but more recently allowing for direct connection between devices. The ways in which Wi-Fi is used in cameras can vary. Thus, the most popular option is to connect to a smartphone, tablet or other similar device for remote control (see below) and / or transfer footage to an external device. Some cameras have built-in software that allows you to directly connect to the Internet through wireless access points and upload photos and videos to popular network services. And in models running Android (see above), specific features depend only on the installed software and may include full access to social networks through client programs (see below) and even web surfing through a browser.
— Bluetooth. A wireless interface used to communicate with various electronic devices. In cameras, Blu
...etooth is most often used to connect to a computer or laptop and transfer footage; In addition, it allows you to use the direct printing function on printers equipped with Bluetooth. The range of Bluetooth communication is up to 10 m, and the devices do not necessarily have to be in direct line of sight to each other.
- NFC chip. NFC (Near-Field Communication) is a wireless communication technology designed to connect various portable devices with each other at a distance of up to several centimeters. In cameras it plays an auxiliary role, designed to facilitate connection with other devices (smartphones, tablets, etc.) using a longer-range standard (Wi-Fi or Bluetooth). Instead of delving into the settings - looking for devices, connecting them manually - just bring the NFC camera to a gadget equipped with the same chip and confirm the connection request.
— Control from a smartphone. The ability to remotely control the camera using a smartphone, tablet or other similar gadget. The connection between the camera and the control device is usually carried out via Wi-Fi (see above), while a special application is used for control, and the gadget’s screen plays the role of a viewfinder. The specific capabilities of such control can be different - releasing the shutter on command, selecting exposure parameters and other shooting settings, focusing by touch, etc. Often, it is also possible to “drain” the footage onto the control device and, through it, to the Internet. Note that for cameras used with mobile phones (see “Camera Type”), this function is not indicated: such a camera is usually mounted directly on the device, and there is no talk of remote control.
