After more 10 days of experimenting, I have a new version of SX110 profiles, so you can download them here (althouh it doesn't seem that there was a big demand for them, as there were no responses). This is "build number 105"
http://www.megaupload.com/?d=56G5C6F0In the archive, you can find:
Canon SX110 - Camera Standard 105.dcp
Canon SX110 - Camera Vivid 105.dcp
Canon SX110 - Camera Positive Film 105.dcp
These DNG color profiles should produce similar colors like camera picture styles. In this version, I sligtly corrected position of green primary, because green colors had lower hue than on jpegs from camera. In case of Camera standard, most colors match jpeg quite good. There are some differences in light orange color, which has slightly lower hue, and cyan color is more saturated. Further improvements can be obtained by modifying HSV lookup table with Dng Profile Editor, but I was satisfied with result and leaved it as is. Luckily, Adobe tuned G9 HSV lookup table, which is used here, without desaturation shadows, that's another difference
Canon SX110 - Adobe Standard 105.dcp
This profile has Adobe standard lookup table. I made previous version by combining matrices from Canon SX110 - Camera Standard 104.dcp and HSV lookup table from G9 Adobe profile. Profiles for other cameras, supplied by Adobe, are made this way. But it turned out that some colors were slightly off (sky hue was too low, it looked slightly cyan), obviously because G9 lookup table is slightly different from lookup tables inside SX110, so I had to correct matrices for Adobe standard profile to get correct hues.
Canon SX110 - 400D Standard 105.dcp
This profile should produce similar colors like 400D raw, developed with Digital Photo Pro. It uses the same matrix set as Adobe Standard 105. I also changed tone curve in the profile (used a curve from Camera profile), so that image is aproximately as bright as with other profiles. With previous version, it was darker, because original curve takes into account highlight headroom in 400D.
For usage with old versions of ACR and other programs that don't support DNG profiles, there is also a new version of simple color matrix:
0.5302 -0.0426 -0.0330 -0.5254 1.0927 0.2237 -0.1037 0.1179 0.4216
In ACR, this profile is named "Embedded". I tuned it to be similar to Adobe standard DNG profile 105, with some differences, mostly in red/orange/skin range. It's not possible to have correct red hue and skin tone hue without using profiles. There is another drawback with using only one color matrix - it is tuned for daylight, so indoor photos taken without flash, with low color temperature, can have slightly shifted colors (red can have magenta tone etc)
There's an interesting reading about color profiles here (check also part 2 and 3)
http://chromasoft.blogspot.com/2009/02/visualizing-dng-camera-profiles-part-1.htmlAuthor of that blog made a command-line utility dcpTool, which can also be useful
(I used it to replace a tone curve in 400D Standard profile)
http://dcptool.sourceforge.net/Introduction.htmlI also included a new version of DngSet/GetMatrix. Now, it's only one program, named DngMatrix, which can be used to write, display or copy color matrices, depending on parameters
Enjoy
