A twist-lock mechanism used almost universally for mounting lenses on camera bodies. You line up two dots, one on the lens barrel and one on the camera body and insert the lens, then twist the lens in the mount until it locks into place. The lens is released again by pressing a button on the camera body to release a catch, then twisting and removing it.
Company which champions old, analog cameras, outdated or cross-processed film and relaunched classic lens designs. Lomography products are known for their expense, sometimes makeshift construction and general unpredictability, but also revered by their fans for these very reasons (well, probably not the expense), because they introduce the kind of randomness, unexpectedness and engagement lost in the transition to modern digital imaging.
Billingham is a prestige camera bag maker in the UK’s West Midlands. It produces traditionally-styled canvas or FibreNyte material bags with brass fittings, leather straps and great attention to detail. Despite the traditional appearance, Billingham bags are designed for modern cameras and users, and owners hold them in high regard.
LUT stands for ‘lookup table’. Essentially, it takes the colours in an image and remaps them on to new ones. It really is a table consisting of a large grid of colour swatches and how they should be adjusted in the converted images. Its closest equivalent is the device profiles used in colour management systems, which work on a similar principle, but LUTs are usually designed for creative effects rather than colour correction.
LUTs are often used to simulate classic films or filter effects. They’re commonly distributed as preset effects for programs like Lightroom, Capture One and now Skylum’s Luminar image-editor. It is possible to create your own LUTs, but it’s a somewhat technical process.
The advantage of LUTs for image editors is that they are, in theory, software independent. The same LUT (or image effect) can be used in any software that can import and apply lookup tables.
The disadvantage is that the LUT effect can’t be edited. It’s a straightforward colour conversion with no user-editable settings, though you can of course add other image adjustments in the software used to apply the LUT.
The video equivalent of the image-enhancement stills photographers carry out on their images. Videographers ‘grade’ video to match the colours and exposures between clips, to create a certain ‘look’ or to edit video shot in a ‘log’ mode for extra dynamic range.
