Feature on some cameras and in some image-editing programs that lets you recover very bright or dark areas of the picture which would otherwise be lost to over- or under-exposure. It uses the extra image data captured in RAW files, so you have to shoot RAW to be able to do this later on a […]
When you shoot RAW files there is often a little extra highlight detail in the data than is initially visible, and a good RAW converter will be able to recover this detail to correct any ‘blown out’ areas. There’s no much margin for correction, however – typically you might be able to recover 1EV of […]
A feature on some cameras which expands the range of tones the sensor can capture. It works by reducing the exposure to be sure of capturing extended highlight detail, then modifying the tone curve to restore midtone brightness.
This is the brightness range the camera can capture before starting to lose detail in bright areas (like the sky) and dense, dark shadows. Generally, the larger the camera’s sensor, the better its dynamic range. RAW files capture a slightly wider dynamic range than JPEGs.
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.
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.
