Adobe Cinema DNG

[Ron B]

I use the Adobe DNG Converter to convert the Panasonic RW2 raw files from my Lumix LX5 so I can edit them in Photoshop CS4. I came across Adobe Cinema DNG, not sure exactly what it does.
Anyone have any experience using it?

[aedipuss]

converts some types of camera raw files to a type of tiff file.

Yes, it does. Have you ever used it? I'm trying to determine what situation you might want to do that.

when photoshop/other photo editor can't read the raw files.

The Cinema DNG is an attempt at standardizing a format for aquiring, importing and archiving the raw video data captured by camcorders. Some high end video cameras used in the film industry can capture and store the sensor data before it's processed (de-bayered/compressed, etc.) in an MXF wrapper or as individual tiff files. Different cameras have different formats for this raw data. Converting to the Cinema DNG format will allow any program that can import the DNG format to use the data from different cameras. Kind of like taking video from different cameras and resolutions and transcoding it to Cineform HD so you have a single format for editing, except the DNG format keeps it in it's raw state.

close but dng is a lossless TIFF format, not a raw format.

close but dng is a lossless TIFF format, not a raw format.

But on Adobe own page it says:

The CinemaDNG file format is designed to store high-resolution video streams in camera raw format...

[aedipuss]

from the adobe dng spec manual -

DNG is an extension of TIFF 6.0 and is compatible with the TIFF-EP standard. See these specifications for more information on TIFF and TIFF-EP:

Yes, DNG is being added to the TIFF specification, but the DNG format will store raw sensor data.

The DNG Format

The camera sensor output can be stored directly into the DNG image file, without in-camera pixel processing or repackaging of the sensor data. The DNG image format is widely used to capture and archive camera raw images. Tools are available to convert images from over 200 proprietary camera raw file formats to the DNG format. The DNG format specification is now being incorporated into the ISO 12234-2 standard as TIFF/EP Profile 2.
DNG options in CinemaDNG include:

• Image data from a single-chip image sensor (with color filter array) or a multi-chip image sensor (without color filter array)
• Sensor values of any bit depth from 8 to 32 bits
• Arbitrary-size color filter arrays with up to seven different filter colors
• Arbitrary image height and width
• Lossless compression
• Black level, white level, and linearization parameters for decoding and scaling of sensor values
• Color-processing parameters for mapping sensor values to CIE XYZ color space
