Almost colourless filter which is designed to cut blue (UV) haze in distant scenic shots, though this is less of an issue with digital imaging than it was with film. UV filters are still used, though, as a simple and inexpensive lens protector.
Standard connection between cameras and computers, though these days most photographers would remove the memory card and use a card reader to transfer photos. USB ports can also be used for charging on some compact cameras and ‘tethered shooting’ on professional cameras.
A set of perspective controls which can correct converging verticals, skewed horizons and other perspective problems. Lightroom offers a set of automated one-click buttons which often fix the problem immediately, plus a manual tool for correcting more complex or difficult perspective problems.
Where a picture comes out darker than you expected because of the way the camera has adjusted the exposure, or where you deliberately make the photo come out darker for dramatic effect.
UHS is a new ultra high speed bus (data transfer connection) for SD memory cards. There are two versions: UHS-I and a more advanced UHS-II type. This refers to the physical construction of the card and does not directly indicate its speed. There are speed standards for UHS cards: UHS 1 guarantees a minimum speed of 10MB/s, which is suitable for full HD video recording, and UHS 3 guarantees a minimum transfer speed of 30MB/s, which is what you’d need for 4K video.
