Created attachment 140927 [details] Difference between preview and editor SUMMARY When an image is opened to edit, sometimes (not always) the exposure seems to be corrected to the worse. See attached screenshot: the left half shows the embedded jpg preview, the right half shows the editor. The left image is how I wanted it to look when I set the camera to shoot the picture. The image is taken in ARW format. (Sony camera) Neither knowingly nor willingly did I set any option that says I want those changes to be made when editing an image. Operating System: KDE neon 5.22 KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.85.0 Qt Version: 5.15.3
A "faster" preview should be loaded in the preview. You can set the digiKam settings under "View" to load the full JPG image or, in the case of RAW, half a RAW preview. Then the images look pretty much identical. The ARW format also has a bit of a problem, as the embedded preview is often very, very small. Other manufacturers embed a better preview in their RAW formats. Maik
I found that settings, but the result is not what I want the picture to look. Like I said: I choose the camera's settings deliberately so that the picture should look like on the left part of the screen shot. That's what I could see on the camera's live viewer: the cam shows the picture as it will look like later, including FOD and exposure. I can open the ARW with Rawtherapee and with Darktable, and in both programs the editor shows the image as in the left part of the screen show. Only Digikam's editor changes the picture without the user's doing. So, two out of three programs show the picture as desired. Where's is the error?
We already have a bug report on this, I'll find it out. digiKam automatically adjusts the exposure. Otherwise you have to choose to display the RAW decoder settings when opening the image in the editor and adjust the settings yourself. Maik

I checked the settings: none of the options under "Editing" is set. Still, the image is much too bright when opened in the editor. But: there's a button called "use default" on the top of the editor's window. When I click it, the image looks as desired! But this setting is not saved: I have to use that button every time I edit an image. How do I turn this option into default option?
Which "use default" button do you mean? You can deactivate the auto brightness function under digiKam Settings-> Image Editor-> RAW Default Settings-> [x] Auto Brightness. Maik
