Falsche Farben in Camera RAW

Hallo ,

Ich habe einen neuen PC und dementsprechend alles neu installiert.

Die Einstellungen habe ich genauso gemacht wie beim vorgänger PC inkl. speziell von Profis erstellten icc und icm Profil.

Wenn ich meine Bilder normal öffne ist alles gut , aber wehe ich öffne etwas in Camera RAW . Dort wird mir das Bild in den leuchtensten Magentatönen und viel zu dunkel angezeigt(obwohl alle regler auf null). Ich habe soweit ich konnte die Farbeinstellungen in Br überprüft ,aber kann keinen Fehler entdecken.

Habt ihr ne Idee?

Correct answer D Fosse

To answer your question, yes a monitor profile is accessed by the same methods for both ACR and Photoshop. So you are correct that the profile is used by both software's and would have the same effect on color being displayed

@Bob_Hallam , not necessarily. They will if the profile works correctly. But what we're discussing here is a possibly defective profile. It's well known and well documented that bad profiles can behave differently in different color managed applications.

Or between Lightroom Library and Develop.

Even if it all ends up in the same monitor profile, the source color spaces are often different (like here). So the conversion calculation itself is different, and one can work and the other fail.

This has to be either a broken monitor profile (my first guess), or a GPU/driver bug.

No incorrect or missing color profile in the image could produce a result like this. Even going from sRGB and assigning ProPhoto doesn't come near this.

Also note the obviously falsely colored (too blue) histogram. The histogram is displayed with color management in these applications and is a good indicator.

Hallo, Danke für die Antwort.

Aber würde ein defektes Monitorprofil nicht dazu führen das die Farben überall falsch dargestellt werden? Es ist ja nur in Camera Raw. Wenn ich das Bild in Fotoanzeige oder in anderen Programmen anzeigen lasse ,sieht es ganz normal aus.Also muss es ja an Camera Raw liegen . Aber ich kann da nichts ändern.

By @Claudili77

No, that's a common misunderstanding. Monitor profile and monitor calibration are two entirely different things.

The monitor profile is a standard icc profile, used in a standard profile conversion. This conversion is performed by the application on the fly, as you work.

The monitor profile is a description, or a map, of the monitor's current behavior in its calibrated state. The profile has a much higher precision level than the calibration, and uses many more parameters. It is also what makes it possible to work in any other color space than sRGB.

Like any other map, the monitor profile has to correspond to the actual terrain. If the profile is not an accurate description of the monitor, the conversion is not accurate and produces the wrong result. Then the application cannot display correctly.

A marginal profile, or one not correctly written to icc specification, can work in one application but fail in another. It can also work from one source color space but fail from another source color space. Both those conditions potentially apply here.

Try resetting your ACR preferences, better?

Hold down the Command key and select Photoshop > Preferences > Camera Raw (MacOS*) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).

Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

*On Ventura, it is now called "Settings".

Wo soll ich was zurücksetzen? Da passiert nichts wenn ich STRG Taste drücke. Zurücksetzen Funktion gibt es in CameraRaw nicht.

You reset Adobe Camera Raw preferences (different from Photoshop) using the key commands from here:

Make sure when comparing applications on the same image that the image includes an embedded ICC profile that describes how you expect it to appear on screen. Sometimes when files do not have an embedded profile and color settings are different between applications (sRGB for PS and Adobe RGB for ACR the image will naturally appear different. You can also check and change your color settings in ACR to match Photoshop. That should solve your issue.

In PS sieht das Bild ja normal aus. Nur in Camera RAW nicht. Und die Einstellungen sind in allen Programmen gleich.

Does the image your using include an embedded profile? If so uninstall both PS and ACR then reinstall them. Remove the preferences in your system folder before re-installing.
