A HDR (High Dynamic Range, azaz nagy dinamikatartomány) egy olyan módszer, amely a kép legvilágosabb és legsötétebb részeinek részleteit rögzíti. Lényegében egy olyan fényképről van szó, amelynek több rétege van. Leggyakrabban egy alulexponált, egy túlexponált és egy expozíciókorrigált fénykép. Ha összeadjuk az egyes különböző expozíciójú fényképek dinamikatartományát, akkor egy nagy dinamikatartományú fényképet kapunk.
A folyamatosan fejlődő technológiák új Ultra HD és 4K felbontásokat hoznak magukkal, amelyek lassan felváltják a megszokott Full HD szabványt. A nagyobb felbontások négyszer több pixelt és nagyobb bitrátát kínálnak. Megjelennek a digitális videófelvételekben és a számítógépes grafikákban.
HDR is an abbreviation that you often see nowadays when selecting a television. What exactly does it mean...
The viewfinder is a device on a camera used for framing and focusing the picture.
A tripod is an essential photographic tool used to stabilise the camera during long exposure shooting.
The tripod head attaches the supported device (e.g. a camera) to the tripod legs and allows the device to be locked or positioned in different ways. Tripod heads differ according to the clamping mechanism used and method of adjusting the axis.
Image stabilisation helps to prevent blur caused by camera shake. You should consider getting a lens with image stabilisation if you capture many zoomed-in shots or shoot without a tripod.
Video formats mark a file format of a recorded video. The format helps you find out whether the video can be played on your TV. There are a number of both free and paid programs which convert video files to supported formats.
HDMI is the most widely used digital connector for simultaneous audio-video transmission. Cameras often feature a mini-C or micro-D version. To connect the devices to your TV, you need to purchase a corresponding cable, which is not included in the package.
Ultrazooms are compact cameras with a long zoom range, which is typically ten times higher. To fully make use of the potential of such cameras, it should feature optical image stabilization. With a long zoom range, the slightest hand movement can cause image blurring.
A compact camera where the image captured by the lens is projected electronically onto a miniature display. Its lack of an optical system means makes it significantly lighter and more portable. Another nice bonus is the ability to view the image on the display with effects already applied.
Timelapse is a technique where the frequency at which film frames are captured is set at specific intervals. The camera captures hundreds or thousands of photos in succession and then the result is played back, creating a stunning movie. One significant drawback of this type of photography is its relatively fast shutter wear compared to the lens, especially when shooting at close range. These days, however, you are far more likely to find a camera with a preview LCD display instead.
NFC (Near-Field Communication) is a short-range wireless connectivity standard used to establish communication between portable devices in close proximity to each other (up to 4 cm). For example, to transfer photos and videos using Bluetooth or WiFi, you simply touch your camera to your phone and wireless connection is established automatically. Of course, NFC must be supported by both devices.
A built-in WiFi adapter is used for wireless transmission of data to smartphones, tablets or computers. You can also connect to the Internet and automatically share photos on social networks, such as Facebook, Twitter, Instagram and so on. You'll appreciate the remote-control feature, which allows you to control the camera with the help of your phone or tablet.
Cameras with a GPS sensor store in EXIF metadata coordinates of a place where the pictures were taken. Even years later, you can pinpoint the location on the map and possibly take the same photo again later to see what has changed. Some devices include an electronic compass, which allows you to observe not only the position of your camera but also the direction of the lens.
