A DCP files editor. dcpTool is a command line utility for processing DNG Camera Profiles (.dcp files). DCP files are an open standard for defining the color rendition of digital cameras, and are used by various Adobe products including Lightroom and Photoshop/Camera Raw.

For those coming to this site just for information on what these profiles actually are rather than dcpTool, that's on this page.

dcpTool can do five things:
1. Decompile binary format DCP files into a text based XML format. This XML file can then be studied and/or edited with a text editor or specialized XML tool.
2. Compile XML format DCP files into binary files that can be used with any DCP aware software.
3. Extract DCP profiles that are embedded into DNG files into a separate DCP file.
4. Make a profile Invariate. An invariate profile won't cause changes tint when you make adjustments to exposure settings. More on this on the Hue Twists page.
5. Untwist a profile. An invariate profile won't change color when you adjust exposure settings, but still has hue twists embedded within it. Untwisting a profile removes all hue twists totally. More on this on the Hue Twists page.

dcpTool is a command line utility which is used as follows:
dcpTool [options] file1 [file2]

Valid options:
-h Print this message
-c Compile file1(xml) to file2(dcp)
-d Decompile file1(dcp) to file2(xml) (default)
-i Convert file1(dcp) to invariate file2(dcp)
-u Convert file1(dcp) to untwisted file2(dcp)

The easiest was to use dcpTool is to open a terminal in the location that you copied the binary files to. e.g., if you copied the files to a DCP folder on the desktop, and have a file called test.dcp in that directory as well, you would open a terminal, then:
In Windows: dcptool -d test.dcp

Please Note: The Windows version of dcpTool requires that three dll's (inconv.dll, libxml2.dll and zlib1.dll) be in the same directory as the executable file. Make sure to copy these as well.
