A lighting unit designed specifically for video, typically small and light enough to mount on the camera or alongside it on a video rig. Some flashgun makers are now building a small video light into their flash units.
Nikon’s name for its image stabilisation technology, as built into its DSLR lenses. Tiny gyroscopic sensors detect any camera movement during the exposure and instantly shift a group of internal lens elements to compensate and keep the image steady on the sensor.
A special type of distortion correction once built into DxO Optics Pro but now built into the separate DxO ViewPoint application. It fixes the distortion usually seen with wideangle lenses where objects near the edge of the frame appear disproportionately wide – it’s most obvious with human figures.
Viveza is a software plug in which offers localised adjustments for photos via ‘control’ points. It’s part of the Google Nik Collection. You can use it to apply dodging and burning effects to enhance colour images in just the same way you would in black and white.
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.
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.
Any effect which gives the look of an old photo, including sepia toning, photo borders, paper patterns and textures and anything else which gives a distressed, ‘aged’ look.
An effect where the edges of the picture are darker than the centre. It was common with old lenses and it’s become associated with a vintage look. It’s considered a lens aberration these days, though photographers often like to add a vignette effect deliberately.
Software that corrects distortion using lens correction profiles, fixes volume deformation created by wideangle lenses and offers perspective correction tools for fixing converging verticals and more. Works as a standalone app or as a plug-in and also integrates with DxO Optics Pro. See also: DxO ViewPoint 3 review
These are an option on both DSLRs and in electronic viewfinders. You can use the grid to make sure horizons are level and buildings are vertical – some grids confirm to the ‘rule of thirds’ to help you get a satisfying composition.
The percentage of the scene shown by the viewfinder. In better DSLRs you see 100% of the scene that will be captured, but in cheaper models it might only be 95-97%. That small difference can lead to objects showing at the edge of the frame that you hadn’t realised were there.
Almost all digital cameras can now shoot video as well as stills, and as well as its leisure applications, video is also increasingly important to professional photographers as clients frequently want movies as well as still images. The key specifications are the resolution (standard HD, full HD or 4K) and the frame rates (30fps, 25fps […]
A more sophisticated version of the regular saturation adjustment which targets the weakest colours rather than applying a constant saturation increase across the whole range. It’s less likely to produce solid, ‘clipped’ colours and can give a more natural, more controllable colour boost.
Tools use for drawing shapes rather than editing the pixels in photos. Vector shapes are described mathematically, so you can scale them up to any size without quality loss, edit them after they’ve been created and combine them in different ways. In photo editing, they’re most likely to be used for makign a very precise […]
Used in Capture One Pro to create different versions of a photo without physically duplicating the image file on your hard disk. Capture One Pro’s adjustment are non-destructive, which means they consist of processing instructions rather than direct adjustments to image files. Lightroom has a similar feature called ‘Virtual Copies’.
