Digital Negative (DNG) is an open, lossless raw image format developed by Adobe and used for digital photography.It was launched on September 27, 2004. [1] The launch was accompanied by the first version of the DNG specification, [2] plus various products, including a free-of-charge DNG converter utility.
The raw file (left) before highlight and shadow details were recovered using the levels tool (right) When a camera saves a raw file it defers most of this processing; typically the only processing performed is the removal of defective pixels (the DNG specification requires that defective pixels be removed before creating the file [36]).
The ETTR exposure is, by its very nature, established with a camera ISO setting that allows the exposure indicators (right edge of histogram or blinkies/zebras) to indicate when the sensor is at or near saturation for desired highlights. Most people will find this to be the camera's base (lowest, not false) ISO.
ORF files have to be copied to a PC's hard disk, and then one can resort to an extensive array of adjustments. The format allows users to achieve maximum precision by setting their own white balance and saturation values, which is not feasible in JPEG or TIFF. This approach is used by experienced professional and devoted amateur photographers.
Adobe Systems has released the DNG format, a royalty-free raw image format used by at least 10 camera manufacturers. Raw files initially had to be processed in specialized image editing programs, but over time many mainstream editing programs, such as Google's Picasa, have added support for raw images. Rendering to standard images from raw ...
Exchangeable image file format (officially Exif, according to JEIDA/JEITA/CIPA specifications) [5] is a standard that specifies formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners and other systems handling image and sound files recorded by digital cameras.
Camera file systems can usually be accessed by directly mounting them via the USB mass storage device class protocol, which exposes the file layout, whether DCF compliant or otherwise. Alternatively, and independent of DCF, files may be accessed via the Picture Transfer Protocol , which provides an object-oriented view and need not expose the ...
Some Nikon Coolpix cameras which are not advertised as supporting a RAW image format can actually produce usable raw files if switched to a maintenance mode. [26] Note that switching to this mode can invalidate a camera's guarantee. Nikon models with this capability: E700, E800, E880, E900, E950, E990, E995, E2100, E2500, E3700, E4300, E4500.
