Ich wechsel wieder zu Englisch, damit der Rest auch was davon hat

Walter suggested, that I use an EXIF tool to read all my EXIF files and it showed me a exposure compensation of 0 even if it said 1.7 in the windows exif exposure value (right click on image --> properties --> details). As long as the latter is not 0 luminance HDR can produce good HDR, when it says 0 (in M mode) I get bad results. Trial of photomatix worked with both. I dont want to discuss software issues here but was just wondering why these exposure values differ in M mode in my EOS 350D. It also reads 0 in the EXIF tool under exposure compensation but reads something other than 0 during bracketing in the windows properties of the file. Oh man, this is gettin complicated...
