Adobe DIGITAL NEGATIVE CONVERTER 3.0 - READ ME Manuel utilisateur

Adobe®Digital Negative Converter 3.0 Read Me

What is a Digital Negative (DNG)?

Digital Negative (DNG) is an openly published raw file specification that stores the “raw” pixel data

captured by the digital camera sensor before it has been converted to JPEG or TIFF along with standard

EXIF metadata, date, time, camera used, and camera settings. This format is freely available for other

software and hardware vendors to support.

What is the Adobe (DNG) Converter?

The Adobe DNG Converter enables you to easily convert camera-specific raw files from the supported

cameras listed below to a more universal DNG raw file.

What is a “raw” file?

A raw file contains the “raw” data captured by the digital camera sensor before it has been converted to

JPEG or TIFF. Cameras that create JPEG or TIFF files process (and in the case of JPEG files,

compress) the sensor data. When working with raw files, the file is not compressed or processed in the

camera—instead, our software gives the user complete control over the conversion settings. For

example, white balance is not applied to the raw file but is stored with the file so the software can default

to the originally intended setting. Other information contained in a DNG file includes standard EXIF

metadata (just like in JPEG files), date, time, camera used, and camera settings.

Benefits of raw files

Some of the benefits of shooting raw include:

•Smaller files than uncompressed TIFF

•Does not have the artifacts of compressed JPEGs

•Many key camera parameters, such as white balance, can be modified even after the image is

captured

•You have complete control over conversion settings rather than letting the camera decide

•Access to 16-bit data for greater detail and fidelity

•Flexibility of converting a single file using multiple conversion settings

Why convert to DNG files?

Unlike most manufacturer-specific raw formats, the Digital Negative is an openly published specification

that not only is supported by Adobe, but is also freely available for other software and hardware vendors

to support. Consequently, it can be a safer file format to use for long-term archival purposes. Archiving

your file as a digital negative eliminates worries that the raw file will no longer be readable once the

camera that created it becomes obsolete.

The Digital Negative specification allows for not only all of the pixel information stored in current raw

formats, but also for all of the additional, proprietary metadata that many manufacturers include. The

Adobe DNG Converter may in some cases ignore some of this proprietary metadata, and only include the

basic information necessary for creating a high-quality image file. The original raw file, however, can also

be embedded in the new DNG format to ensure proprietary metadata from the manufacturer is not lost.

How to Use the Adobe DNG Converter

1. Launch the Adobe DNG Converter by double-clicking on the icon.

•You can also drag and drop individual images or a folder of images directly onto the Adobe DNG

Converter icon. This will automatically launch the converter.

2. Select the folder of images you would like to convert to DNG.

3. Select the location you would like the new DNG files to be saved.

4. Select the name you would like to use for the new DNG files.

•If you select “Document Name,” the existing name of the file will be used with the new DNG

extension added.

•You can choose to add serial numbers or letters to the name. An example of the name will

appear after “Name Example.”

•Begin numbering: Enter the starting serial number if you would like it to be different than one.

•File Extension: The file extension is automatically set to DNG. You can choose the extension to

be either upper or lower case.

5. Preferences are set to “Compressed (lossless)” and “Preserve Raw Image” by default. You can

change those preferences by clicking on “Change Preference…” Below is a description of the

different settings.

•Image Conversion Method:

oPreserve Raw Image – the image data is stored in the original “mosaic” format, if

possible, which maximizes the amount of data preserved. Mosaic image data can be

converted to linear data but the reverse is not possible.

oConvert to Linear Image – the image data is stored in an interpolated (“demosaiced”)

format. This can be useful if a camera’s particular mosaic pattern is not supported by a

DNG reader.

6. Click on “Convert”

7. A dialog will appear showing the status of the conversion.

How to open DNG files in Adobe Photoshop®CS2 and Photoshop Elements
