New project: camera color profile calculation

ArtDen

xbc
I included support for SD600 into 0.2.3-beta7: DNG4PS-2
To test your results, just press green "Save" button in calibration dialog and the program stores your color matrix for camera profile

Defined and auto white balance would be fine in this project.

ArtDen

bether, I don't understand you 😀

bether

Sorry.
I thought about similar settings.

But maybe this is not necessary, because these DNG will be altered e.g. in photoshop.

ArtDen

bether, dnh4ps2 doesn't apply white balance, it only converts nonstandard CHDK RAW file into standart DNG one

I made some modifications for the 0.2.3 beta to compile in MacOSX Leopard. This is based on the work of
Sperber, I only modded some lines in the MAKEFILE for it to work with the 0.2.3 beta sources.

Follow the instructions at http://spebbe.googlepages.com/ and use this modded Makefile

Makefile

I also had to add

#define _UINT32

to the src/external_libs/dng_types.h

becuase if not OSX refused to compile.

This is missing the cool logo that sperber put, but well it works. If you want I can also post the resulting binary. I know have a beta version for PC and OSX

Better to write here about MacOS build: DNG4PS-2 Mac OS X build

Thanks for the tip, I will post it there. I am new to this formus so I haven't had time to read a good set of posts to be in the know.

Here is a sample (i took 2 pictures to be shure) for Digital IXUS 750
ixus750.zip - 18.55MB
Could it be possible to integrate that into the next beta release?
thanks in advance

ArtDen

ulukai, Try 0.2.3 beta9: DNG4PS-2

ulukai

hey thanks, works just fine!

ArtDen, could you include SD630 (Ixus 65)? It's the same sensor as SD600, so profile probably should be the same.
If I use SD600 settings from beta with SD630 files, it says "Cannot find profile for that camera".

there's pictures:
zSHARE - sd630.zip

I have some questions to the actual beta 9 ....

I know it's a beta and some functions may not work correctly - but I like to learn how they should work.

Tab: Camera types
Here I have to select ONLY a camera if there would no JPG.
If selected one camera, how to delete this selection. Is there any trick?
What exactly happens, if there is a selection for the correct camera, what is going wrong?

Tab: Camera options / Color Matrix #X
The selection "Illuminant" hasn't any influence to the Matrix?
Will this selection correspond with the EXIF-information?
How will Color Matrix #1 und #2 work together?

Thanks in advance

ArtDen

gramas, your images is not suitable for color matrix calculation. Try to make white background (or border) for my image when you will take a picture

chiptune, I will look at your remakrs after my holidays 😀

gramas

one more try for sd630:

gramas, try dng4ps2 0.2.3-beta10: DNG4PS-2

gramas

Thanks ArtDen! Works great!

ArtDen

gramas, just check do colors match real ones after developing DNG file

ArtDen

dng4ps2 0.2.3-beta11 contains support for A450
