LightZone edits both RAW and JPEG format images.
LightZone can create and apply pre-determined image transformations, called "styles", to an entire batch of images in a single operation. Using styles, photographers make and save their own preferred compensations for each RAW image based upon camera specific characteristics. Once created, a style is easily applied to multiple images, allowing those standard camera compensations to be applied to every image before the photographer ever views or edits it.
LightZone is a non-destructive RAW editor. It treats the digital image original (typically a RAW file) as precious and non-editable. When LightZone edits an original digital image, a new resulting post-edit image file is created (for example a new JPEG copy) and the original image file is left unaltered. By being non-destructive LightZone preserves the original "digital negative" which contains the maximum information originally captured by the camera, and allows additional images with different transformations to be produced from the original.
LightZone outputs JPEG files which contain metadata references to the original image file location and a record of the transformations applied during editing.
Because the JPEG output files that LightZone creates contain the entire transformation history, edits can always be undone in a new edit session, long after they were saved. Indeed, the same transformations can be easily reordered and additional transformations applied subsequently to yield further image improvements. Additionally, since transformations always begin with the original RAW image rather than an intermediate JPEG version, JPEG compression related editing artifacts are avoided.

Famous quotes containing the word features:
“Each reader discovers for himself that, with respect to the simpler features of nature, succeeding poets have done little else than copy his similes.”
—Henry David Thoreau (1817–1862)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
“The features of our face are hardly more than gestures which force of habit made permanent. Nature, like the destruction of Pompeii, like the metamorphosis of a nymph into a tree, has arrested us in an accustomed movement.”
—Marcel Proust (1871–1922)
