Description DrSlony 2015-05-01 14:03:48 UTC
When digiKam is set to preview raw files using the real raw data and not the embedded JPEG, it applies auto-exposure. Feature request for it not to do that. With the current auto-exposure its difficult to sort bracketed photos or to quickly check which photo is best exposed.

Reproducible: Always

Comment 3 DrSlony 2015-05-03 18:09:43 UTC
Since the two separate reports have been merged though they are not for the same thing, I will paste the other request here:
"I want to see the full sized raw preview and without auto-exposure. digiKam let's me set neither option.
As I reported in another ticket, demosaicing the full 10 megapixel raw takes around 150ms using "fast demosaic" and about 350ms using the great quality "AMaZE demosaic".

Git commit d0a60f5f02890de9e5a5a3e312511930f3cf72a5 by Gilles Caulier.
Committed on 28/07/2016 at 13:54.
Pushed by cgilles into branch 'master'.

Update internal Libraw to 0.18.0 beta (July 2016).

Move Libraw samples compilation rules to core/tests/rawengine. Theses samples
files are now only generated if test code are compiled through right CMake option.

Use DNG SDK source code to compile Libraw in goal to:
   - Decode DNG analog color balances
   - Decode DNG channel black/white level
   - 8-bit encoded DNG files
   - Deflate compressed DNG support with zlib

New features:
   - Support for Black and White Jpeg previews
   - Better intepolation of low-sensitivity pixels on Sigma Quattro files

New RAW cameras supported:
   - BlackMagic Micro Cinema Camera, URSA Mini
   - Canon 80D, 1300D, 1DX MkII
   - Fujifilm X-Pro2 (uncompressed RAW only), X70, X-E2S
   - HTC One A9 and M9
   - Leica M (Typ 262) and X-U (Typ 113)
   - Nikon D5
   - Olympus Pen F, SH-3
   - Panasonic DMC-GX80/85, DMC-TZ80/81/85/ZS60, DMC-TZ100/101/ZS100
   - PhaseOne IQ150, IQ180 IR, IQ3 (all models)
   - Samsung Galaxy S7 (SM-G935F)
   - Sony ILCA-68, ILCE-6300, RX1R II, RX10 III
   - YUNEEC CGO4
