Version: 1.8.0 (using KDE 4.5.5) OS: Linux When importing raw images and e.g. increase EV and then decide the corrections was wrong, lowering EV doens't effect the original image. Only possibility is to revert to original and start over again. Reproducible: Always Steps to Reproduce: (Taken from mail conversation in Digikam-users mailing list) However, I hit another snag when developing RAW files (Sony ARW in my case): it usedd to be that if I added an EV correction, and then decided it was too much, the new (lower) correction was applied to the original RAW output (i.e. an image update after having lowered an EV correction was less luminous); with the 1.8.0 version, the second lower correction is applied to the already corrected image => severe over correction and no way to get back, except through an update in the RAW tab (say I start with a correction of +.3, then decide +.2 would have been better: in <=1.7.0 I ended up with a correction of +.2, in 1.8.0 I end up with a correction of +.5...) Expected Results: Have the original images as base for all corrections.
(Taken from mail conversation in Digikam-users mailing list) Reinstalled kipi-plugins 1.7.0, still problems. Then resinstalled digiKam 1.7.0, all back to normal again. Tested with a new config for a different user. Still same problem. LibKdcraw: 1.1.0 Libraw: 0.11.3
Here's an image to test with(Canon CR2): http://www.adrive.com/public/1528c14240e0794c7a8e2fbc558241e6f517cae694a017247e2717534684a1d0.html
Created attachment 56656 [details] Screenshot before EV correction.
Created attachment 56657 [details] Screenshot with 0.50 EV correction.
Created attachment 56658 [details] Screenshot after lowering EV correction to 0.30.
I can confirm the bug. If one uses the EV number box to increase the level to 2.x the image gets brighter. If one then decreases it to say 0.9 the image gets even brighter. digiKam version 1.8.0 Exiv2 kann in JP2 speichern: Ja Exiv2 kann in JPEG speichern: Ja Exiv2 kann in PGF speichern: Ja Exiv2 kann in PNG speichern: Ja Exiv2 kann in TIFF speichern: Ja Exiv2 unterstützt XMP-Metadaten: Ja LibCImg: 130 LibClapack: internal library LibExiv2: 0.20 LibJPEG: 62 LibJasper: 1.900.1 LibKDE: 4.6.00 (4.6.0) LibKExiv2: 1.2.0 LibKdcraw: 1.2.0 LibLCMS: 119 LibLensFun: external shared library LibLqr: internal library LibPGF: 6.09.44 - internal library LibPNG: 1.4.4 LibQt: 4.7.1 LibRaw: 0.11.3 LibTIFF: LIBTIFF, Version 3.9.4 Copyright (c) 1988-1996 Sam Leffler Copyright (c) 1991-1996 Silicon Graphics, Inc.

Marcel, i confirm this dysfunction. Very strange... Gilles Caulier
I cannot reproduce this problem with White Balance tool which use the same Exposure Compensation algorithm. I suspect a problem in GUI of RAW Import post processing settings. Gilles Caulier
It's not only the white balance correction that is affected. I had the same behaviour with brightness. /Anders
I confirm. I suspect that post processing is applied to post processed image previously computed, and not the demosaiced image (both are stored in memory). Gilles Caulier
Marcel, I just tested with 2.0.0, and i cannot reproduce the problem. So, it's only affect 1.x. Gilles
Marcel, If i save demosaiced image like this : void RawImport::prepareEffect() { DImg postImg = d->previewWidget->demosaicedImage(); postImg.save("/home/gilles/demo.png", "PNG"); setFilter(dynamic_cast<DImgThreadedFilter*>(new RawPostProcessing(&postImg, this, rawDecodingSettings()))); } before post-processing adjustements, I can confirm that RawPreview::RawPreviewPriv::demosaicedImg is corrupted after post-processing adjutments. The image must still the same. Look into the code, i cannot see how this DImg is modified by post processing... Note : i also check if post-processing settings is fine, and all values used by post-processing code is fine. Gilles
