Configuring CornerFix

If you have a version of Phase One's Capture One software earlier than version 3 installed, you will have to configure CornerFix's compression settings to work with it.

Various raw converters need different settings as regards compression. Compression options are found in the Preferences->Compression menu. Compression is described in the FAQs, but as a starting point:

1. Adobe applications (e.g., Lightroom): Lightroom will operate with any CornerFix compression settings. For the best combination of speed, file size and freedom from compression artifacts, a good staring point is:
   1. Level compression: disabled
   2. Lossless (Huffman) compression: optional
   3. Capture One V4 Compatibility: disabled
2. Apple Aperture:
   1. Level compression: disabled
   2. Lossless (Huffman) compression: optional
   3. Capture One V4 Compatibility: disabled
   4. Important: For version of OS X later than 10.7.3, you may have to enable "Apple DNG Compatibility" to avoid a green cast when images are viewed in Preview or Aperture.
3. Capture One Version 4 and later. Note: Do not use these settings with earlier versions of Capture One:
   1. Level compression: disabled
   2. Lossless (Huffman) compression: disabled
   3. Capture One V4 Compatibility: enabled
   4. Level compression: enabled
   5. Warning: If you have Capture One V4 Compatibility enabled you must also have the “Display Thumbnails” option enabled. Failure to do this will result in blown highlights in CornerFix's preview pane.
4. Capture One Versions earlier than 4:
   1. Lossless (Huffman) compression: disabled
   2. Capture One V4 Compatibility: enabled
5. Other raw developers: Other raw developers may take some experimentation:
   1. First, try with Level Compression disabled, Lossless (Huffman) compression disabled, and Capture One V4 Compatibility disabled
   2. If that doesn't work, try enabling Capture One V4 Compatibility
   3. If that doesn't work, enable Level compression
