Lighting & FlashSoftbox
A fabric enclosure with a diffusion panel on the front that turns a small light source into a large, even one.
Film, Darkroom & Historic ProcessesSolarisation
A partial tonal reversal produced by briefly exposing a print or negative to light part-way through development.
Colour & Colour ManagementSpectral Power Distribution
A plot of how much energy a light source emits at each wavelength across the visible spectrum.

Lighting & FlashSpecular Highlight
A mirror-like reflection of the light source itself on a glossy surface, rather than light diffusely scattered by it.
Lighting & FlashSpeedlight
A small, portable, battery-powered flash designed to sit on a camera's hot shoe or a light stand.

Files, Metadata & WorkflowStar Rating
A one-to-five scale applied during culling to mark an image's quality or priority.
Motion, Video & Creative TechniquesStar Tracker
A motorised mount that rotates the camera to match the Earth's rotation, allowing long exposures without star trailing.
Motion, Video & Creative TechniquesStar Trails
Arcs traced by stars across the frame as the Earth rotates during a very long exposure or a stacked sequence.
Motion, Video & Creative TechniquesSteadicam
A mechanical stabilising system that isolates the camera from the operator's movement using a counterweighted arm and vest.
