Wi-Fi

An increasingly common feature on digital cameras at all levels. The camera sets up a Wi-Fi hotspot which you can then connect to with a smartphone or tablet. The camera maker supplies an app which you can use for transferring photos to the device and for controlling the camera remotely.

Wind cut

A feature on some microphones that attempts to cut out loud roaring, whistling noise that you might not notice when shooting but which spoils the sound quality. It can be effective, but it’s even better to use a muffler on an external microphone.

White balance

An adjustment made by the camera to neutralise colour shifts in the lighting. Digital cameras offer an auto white balance option where they choose the correction, or you can select manual white balance ‘presets’ when you want to control the camera’s colour rendition yourself. White balance adjustments are made using ‘colour temperature‘ and ‘tint‘.

Watermark

A way of marking images as your own property to prevent others from passing them off as their own or earning income from your work. Watermarks are visible on the image, which is a downside, but they do act as a visible deterrent and warning that you take image copyright ownership seriously.

Warmth

A non-technical way of describing the colour temperature of the light in a scene. Pictures taken with a low sun have ‘warmth’ because the light takes on a golden colour. Many photographs – landscapes, for example – can be enhanced with a little additional ‘warmth’.

Virtual horizon

A kind of on-screen spirit level that shows you when the camera is level. This can be useful in landscape photography, for example, when the horizon isn’t flat or visible. Some also have fore-and-aft levels to help avoid any tilt (and converging verticals) when shooting buildings.

Virtual Copy (Lightroom)

Because Lightroom uses non-destructive editing, its adjustments are stored as metadata (processing instructions) rather than new image files. This means it can create any number of Virtual Copies of the same image for trying out different effects, without having to duplicate the image itself on your hard disk.
