ORF (Olypus Raw File) images have wrong colors (too red)

[LuckyLuke-n]

Hi all,
I need your help with a color issue. After opening with Magick.NET, .orf-files (Olympus Raw Format) appear to have much more red color than they originally have. Below I present you an example.

After opening with Magick.NET	Original image

I have tried this with different formats:

Format	Colors correct?
ORF (Olypus Raw Format)	❌
JPG	✔️
TIFF	✔️

I do this to open the .orf-file and convert it to a bitmap file:

MagickImage magickImage = new(pathToFile);
bitmap = magickImage.ToBitmap();

The same happens when I only save the orf-file as a jpg-file:

MagickImage magickImage = new(pathToFile);
magickImage.Write(filename, MagickFormat.Jpg);

I am very much looking forward to your feedback. Huge thanks in advance.

For the ORF file you probably want to play with the DngReadDefines and adjust some of the settings to get the output that you want.

Thank you very much. This fixed my issue.

In case someone has a similar problem, that is what I did:

// color correction for orf files
DngReadDefines dngReadDefines = new()
{
    OutputColor = DngOutputColor.SRGB, // default
    UseCameraWhitebalance = true // this removes the dreadful red/brown color
};
MagickReadSettings readSettings = new(dngReadDefines);

MagickImage magickImage = new(filename, readSettings);
magickImage.BrightnessContrast((Percentage)0, (Percentage)5, Channels.Red); // this corrects the missing red after correcting the white balance
// magickImage.Sharpen(); // takes quite a long time and would slightly improve the image quality
