Have you ever imported some RAW files and when you first open the image in Lightroom the image is vibrant and looks great and then all of a sudden the image switches to something that is less sharp and the colors are all bland? If you have seen this phenomenon, what you are seeing initially is the embedded JPEG image being displayed first and then the on-screen image changes to the RAW sensor data image. The reason why there is a difference is that the JPEG images have had your camera settings applied to them before being saved. With Canon camera, this is usually Standard, Faithful, Landscape , Neutral, and Portrait. Other camera brands have similar types of basic settings. Many people complained that the JPEG image was often very nice and it took a lot of work to get your RAW images to look as good as the JPEG image.

To solve this, Lightroom needed to have a way to understand what the cameras where doing to the images. Initially, you could use the camera calibration controls to dial in some default settings, but this was really inaccurate and rather a pain to use. Shortly after Lightroom 2.0 came out, Adobe came out with the first beta versions of the camera profiles. These profiles were actually based on the characteristics of the different cameras and can be used to very quickly get your image looking better right from the beginning.

Sometimes the effect is more subtle

For some people who still shoot JPEG instead of RAW, one of the complaints about RAW is that it takes longer to process RAW images to get them look good. Lightroom 2.2 with camera profiles solves this problem quite nicely. You can easily create a camera profile preset (or download ours here) and use them as an import preset so that it is applied to every image as you are importing them. Applying the Standard profile during import will get the vast majority of your images looking almost identical to what you would get from saving the image as a JPEG.

Beta Profiles

If you have installed the beta profiles, you can go ahead and remove them using the following instructions specific to your operating system.

Go to the following folder (based on your operation system) and delete anything with the word “Beta” in it’s title. Then restart Lightroom and all should be good in the world again.

Adobe has also fixed a few bugs that were introduced with the Lightroom 2.0 release:

Lightroom 2 Bugs – Fixed

• Images rendered from the Slideshow export process produced a jagged effect on hard edges relative to the quality of normal JPEG export
• Increased the number of characters allowed in Web gallery labels beyond 150 characters
• Catalogs with hundreds of root (top level) folders caused very slow launch times
• Drag and drop to move a subfolder to a different folder showed the incorrect photos in the grid
• Print Sharpening produced edge artifacts in certain conditions
• Density defaulted to 100 percent for initial stroke regardless of position of slider
• The  Adjustment brush created blocky, straight edges to brush strokes under certain conditions
• Lightroom could become unresponsive when using the graduated filter under certain conditions
• It was possible to lose the ability to edit an adjustment brush setting after applying a graduated filter with hidden pins
• Turning auto-mask on produced a lag in Lightroom performance in when applying the adjustment brush
• Print to JPEG functionality produced a low resolution image when printing photos with panorama aspect ratios
• Extended characters in a folder name caused Edit in Photoshop functionality to fail
• Smart collection did not respond to changes in custom metadata
• Enabling auto-mask produced a lag in performance in when applying the local adjustment brush

Lightroom 2 Enhancements

• Camera profiles are now available in the Calibration panel in the Develop module.  These profiles are designed to provide different interpretations of raw capture.

**With the release of Camera Raw 5.2 (and upcoming Lightroom 2.2 release) there is an important exception in our DNG file handling for the Panasonic DMC LX3, Panasonic DMC FX150, Panasonic DMC FZ28, Panasonic DMC-G1 and Leica D-LUX 4. In this release the native, proprietary files from these cameras can only be converted to linear DNG files. A linear DNG file has gone through a demosaic process that converts a single mosaic layer of red, green and blue channel information into three distinct layers , one for each channel. The resulting linear DNG file is approximately three times the size of a mosaic DNG file or the original proprietary file format.

This exception is a temporary solution to ensure that Panasonic and Leica’s intended image rendering from their proprietary raw file format is applied to an image when converted DNG files are viewed in third party software titles. The same image rendering process is applied automatically in Camera Raw 5.2 and in Lightroom 2.2 when viewing the original proprietary raw file format.

In a future release Adobe plans to update the DNG specification to include an option to embed metadata-based representations of the lens compensations in the DNG file, allowing a mosaic DNG conversion. In the interim Adobe recommends only converting these files to DNG to allow compatibility with third party raw converters, previous versions of the Camera Raw plug-in or previous versions of Lightroom.
