Lightroom 2 Bugs – Fixed

• Lightroom 2.4 on Windows continued to display the import dialog when a memory card was detected regardless of the preference setting “Show import dialog when a memory card is detected.”

Both Lightroom and Camera Raw adds additional raw-support for another 31 cameras, including Canon EOS 500D, Nikon D5000 and 18 Hasselblad models (See complete list below).Beside this the specification for the Digital Negative (DNG) format is updated. DNG is an open archive format for raw-data from cameras. DNG is the answer to the problem with every individual camera and its raw-format. It helps the user to secure the readability of his/her files in the future. For more information about the updated specification for DNG, see www.adobe.com/dng.
