This is Nikon’s name for its full frame DSLRs, to distinguish them from its APS-C size ‘DX’ models. Most Nikon lenses are designed to fit this larger FX format. Those that don’t have ‘DX’ in the model name – though they can still be used on an FX Nikon in ‘DX crop’ mode.
Nikon’s name for its ‘program shift’ control, where you can change the balance of lens aperture and shutter speed without having to leave the program AE mode – you simply turn the command dial until the camera displays the lens aperture or shutter speed you want.
Nikon’s own brand name for the image processors used in its digital cameras. More powerful processors are needed for higher-resolution sensors and faster continuous shooting speeds, and play a part in noise reduction at high ISOs and image quality generally.
This is Nikon’s name for its APS-C format DSLRs. Some Nikon lenses are designed specifically for these smaller format models, and they include ‘DX’ in the lens name to signify that the can’t be used on the full frame models (well, they can, but only in a ‘DX crop’ mode.
A system offered with Nikon DSLRs for dealing with dust spots on the sensor. You take a reference shot of a white card which highlights any dust spots, and then Nikon image-editing software can use this to target dust spots on your photos and process them out.
Exposure adjustment tool offered in some Nikon software for brightening the darkest parts of a picture without altering the rest. It’s a less advanced version of the Active D-Lighting system built into Nikon cameras. Regular D-Lighting just brightens the shadows – it’s too late to adjust the exposure at the software stage.
Wireless flash system used by Nikon to control one or more external Speedlights from one place. Speedlights can even be combined in ‘groups’ for more power or more sophisticated lighting effects.
A flash control mode on some Nikon DSLRs and external flashguns (Speedlights) which can fire other Speedlights remotely via infra-red. It’s possible to control quite complex lighting setups in this way, and it’s part of Nikon’s CLS (Creative Lighting System).
An exposure mode on some Nikon digital cameras which balances up the exposure in high-contrast scenes. The camera reduces the exposure to make sure it captures bright highlight detail and then processes the image to brighten up dark shadows. It can be applied in different strength settings.
