Digital Negative format (DNG)
Digital Negative (DNG) is a file format that contains the raw image data from a digital camera and metadata that
defines what the data means. DNG, Adobe’s publicly available, archival format for camera raw files, is designed to
provide compatibility and decrease the current proliferation of camera raw file formats. The Camera Raw plug-in can
save camera raw image data in the DNG format. For more information about the Digital Negative (DNG) file format,
visit www.adobe.com and search on the term “Digital Negative.” You’ll find comprehensive information and a link to
a user forum.
BMP format
BMP is a standard Windows image format on DOS and Windows-compatible computers. BMP format supports RGB,
Indexed Color, Grayscale, and Bitmap color modes. You can specify either Windows or OS/2® format and a bit depth
of 8 bits/channel. For 4-bit and 8-bit images using Windows format, you can also specify RLE compression.
BMP images are normally written bottom to top; however, you can select the Flip Row Order option to write them
from top to bottom. You can also select an alternate encoding method by clicking Advanced Modes. (Flip Row Order
and Advanced Modes are most relevant to game programmers and others using DirectX®.)
Cineon format
Developed by Kodak, Cineon is a 10-bits-per-channel digital format suitable for electronic composition,
manipulation, and enhancement. Using the Cineon format, you can output back to film with no loss of image quality.
The format is used in the Cineon Digital Film System, which transfers images originated on film to the Cineon format
and back to film.
DICOM format
The DICOM (Digital Imaging and Communications in Medicine) format is commonly used for the transfer and
storage of medical images, such as ultrasounds and scans. DICOM files contain both image data and headers, which
store information about the patient and the medical image. You can open, edit, and save DICOM files in Photoshop
Extended.

transparency in indexed-color images; however, it does not support alpha channels.
