  • Several translation and shortcut corrections were made for the eight additional languages introduced with Lightroom 2.3

New Lightroom 2.4 and Camera Raw 5.4 DNG Options

This release includes new DNG Compatibility conversion options. These choices help address the additional options available with the new DNG 1.3 Specification (http://www.adobe.com/dng):

  • Camera Raw 2.4 and later: The DNG file will be readable by Camera Raw 2.4 (Photoshop CS) and later, and Lightroom 1.0 and later
  • Camera Raw 4.1 and later: The DNG file will be readable by Camera Raw 4.1 (Photoshop CS3) and later, and Lightroom 1.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model
  • Camera Raw 4.6 and later: The DNG file will be readable by Camera Raw 4.6 (Photoshop CS3) and later, and Lightroom 2.1 and later. The DNG file will often be readable by earlier versions, depending on the camera model
  • Camera Raw 5.4 and later: The DNG file will be readable by Camera Raw 5.4 (Photoshop CS4) and later, and Lightroom 2.4 and later. The DNG file will often be readable by earlier versions, depending on the camera model
  • Custom: (Not available in Lightroom 2.4)
    • Backward Version Option: DNG 1.1, DNG 1.3 (default 1.3)
    • Checkbox: Linear (demosaiced) (default unchecked)
    • Checkbox: Uncompressed (default unchecked)

DNG 1.3 Specification Update

The DNG specification has been updated to version 1.3.[LINK] The update includes the following changes:

  • In Chapter 2, “DNG Format Overview”, the section on Defective Pixels has been updated
  • The section on Opcode Lists has been added to Chapter 2, “DNG Format Overview”
  • The CFALayout tag has been updated in Chapter 4, “DNG Tags”.
  • Additional Tags for Version 1.3.0.0 were added to Chapter 4, “DNG Tags”
  • Chapter 7, “Opcode List Processing” was added.
  • “Appendix A: Compatibility with Previous Versions” was updated.

The additional "Opcode Lists" allow complex processing to be moved off the camera hardware, which can have limited processing power, and into the DNG reader, which is often running on more powerful hardware. This also allows processing steps to be specified, such as lens corrections, which ideally should be performed on the image data after it has been demosaiced, while still retaining the advantages of a raw mosaic data format.
