Version: 0.9.4 (using KDE 3.5.10) OS: Linux Installed from: Gentoo Packages DigiKam could use a function that allows the user to restore the highlights of the image. Restoring hightlights is needed for all pixels that have at least one clipped channel. UFRaw suports this. More info about how UFRaw does this: http://people.zoy.org/~cyril/dcraw_lchblend/highlight_recovery_dcraw_lch_patch.html
Already implemented in digiKam 0.9.5 with libkdcraw based on libraw (try last version 0.1.7). Use RAW Import tool for details. It's the same with KDE4 version. Look this screenshot for details: http://www.flickr.com/photos/digikam/3162004701/sizes/o/in/pool-817639@N22/ Gilles Caulier
I forgot to mention that I would like to have this available for all image formats, not only RAW images. Reopen?
Well, i think no, ...because, it's only possible with RAW, before to do all post processing adjustement. Why ? because information is lost especially with highlight. This is the advantage of RAW and 16 bits color depth. Gilles Caulier
Hmm... Well, I never tried it on 8-bit JPEG images but I can't think of any technical reason why it shouldn't work.. The technique is targetted at pixels that have one or two channels clipped. This problem exists in many images, not only RAW images. That is why I think it would be a good thing to allow the user to apply highlight restoration to any image. Another reason why DigiKam should do highlight restoration on any image: When the user processes images in DigiKam, pixel values can clip without the user noticing it. Sure, DigiKam can show clipped pixels in the image. But DigiKam only shows pixels that have all three channels clipped. Pixels with only one channel clipped do not show up. Because DigiKam can easily clip pixels without warning, there should be a means to fix the damage caused by image processing. One more thing: There are more 16-bit image formats besides RAW images. Think of TIFF files. Currently, DigiKam does not allow the user to restore the highlights of these files.
This is similar in nature for Highligh/Shadows feature known from Adobe PS but also present in programs like RawTherapee.
