Camera Raw 5.2

[Brighteyes]

I have downloaded Camera Raw 5.2 and use PSE 6.0. What can you tell me about the Camera calibration feature. There is nothing I can find in the help section.

The best overview I've seen of it is from Adobe's Julieanne Kost, who posted a PDF (http://www.jkost.com/pdf/photoshop/cs4/CR5.pdfnn.com/) discussing the new features in Camera Raw 5.

The engineers have been actively working on improving color rendering for digital raw photographs and as a result, CR5 now supports additional camera profiles which can be downloaded and installed from http://labs.adobe.com. Note: the profiles will begin shipping with the plug-in automatically later this Fall. There are two basic profiles; the Adobe Standard camera profiles that significantly improve color rendering, especially in reds, yellows, and oranges, and the Camera Matching (CM) profiles that emulate the camera manufacturers’ color appearance. The CM profiles are intended for photographers who appreciate the workflow and toolset provided by CR5 but prefer the color rendering provided by the camera vendors’ own software. (All CM profiles are identified with the prefix Camera in ACS’s Profile popup menu.)

Every profile that is provided is camera-specific. Even the older profiles (e.g., ACR 3.3, ACR 4.4) are camera-specific. In fact, the profile menu in CR5 will only show profiles for your camera (for example, if you work with Nikon files, the profiles listed will match the Nikon Picture Controls, or if you work with Canon files, the profiles listed will match the Canon Picture Styles. Note: the CM profiles are NOT expected to match the embedded in-camera JPEG, especially if you have established custom in-camera settings.

You can also find out more on the Adobe Labs site. From the FAQ (http://labs.adobe.com/wiki/index.php/DNG_Profiles_FAQ#WhatIsNewCM):

What are Camera Matching profiles?

These profiles match the color appearance produced by the camera vendors' software, under specific settings (described below). They are intended for photographers who appreciate the workflow and toolset provided by CR / LR but prefer the color rendering provided by the camera vendors' own software.

All CM profiles are identified with the prefix Camera in CR / LR's Profile popup menu.

Please note that the CM profiles are NOT expected to match the embedded in-camera JPEG, especially if you have established custom in-camera settings. To understand the abilities and scope of the CM profiles, please read the following description carefully.

As of July 29, 2008, we have created CM profiles for Canon and Nikon DSLRs only. Photographers who want CM profiles for other cameras are encouraged to use the DNG Profile Editor.

In general, there are 5 CM profiles per Canon DSLR, one for each of the default Canon Picture Styles. These five Picture Styles are called Standard, Portrait, Landscape, Neutral, and Faithful. The CM profiles will match the Canon Picture Styles with all Canon sliders (i.e., Contrast, Color Balance, and Saturation) set to their default values of 0.

Similarly, in general there are 8 CM profiles per Nikon DSLR, one for each of the Nikon Picture Controls. These Picture Controls are called Standard, Neutral, Vivid, Landscape, Portrait, D2X Mode 1, D2X Mode 2, D2X Mode 3. The CM profiles will match the Nikon Picture Controls with all Nikon sliders (i.e., Saturation, Tone Compensation, etc.) set to their default values of 0. Note that the D2X name is applicable to all Nikon DSLRs, even non-D2X models. This is not a bug.

Are the new profiles camera-specific?

Yes. Every profile that we build is camera-specific. Even the older profiles (e.g., ACR 3.3, ACR 4.4) are camera-specific. In fact, the profile menu in CR/LR will only show profiles for your camera. Note that the profiles you see in the profile menu do not include the camera's model name (e.g., Canon EOS 40D). This is intentional (for several reasons).

I only see generic profiles in the Profile popup menu, but not profiles specific to my camera. What's wrong?

Actually, all the profiles listed in the Profile popup menu are specific to your camera. See related question.

I only see an "Embedded" profile in the Profile popup menu. What's wrong?

You probably have a JPEG or TIFF file selected. The camera profiles discussed here only apply to raw files, not already-rendered images such as JPEG and TIFF images.

Hope this helps.
