[QUOTE="J-see, post: 408041, member: 31330"] I've been doing quite some testing the last days and found a reasonable approach that works for me. These are some shots I took each time lowering shutter one stop (of light) and increasing ISO one and another shot keeping ISO at 100. Then I normalized the exposure for the 100 and adjusted it to the higher ISO. The colors are not identical but that can be fixed. Control: [ATTACH=CONFIG]135554._xfImport[/ATTACH] ISO 100 - 200 [ATTACH=CONFIG]135556._xfImport[/ATTACH][ATTACH=CONFIG]135557._xfImport[/ATTACH] ISO 100 - 400 [ATTACH=CONFIG]135558._xfImport[/ATTACH][ATTACH=CONFIG]135560._xfImport[/ATTACH] ISO 100 - 800 [ATTACH=CONFIG]135561._xfImport[/ATTACH][ATTACH=CONFIG]135562._xfImport[/ATTACH] ISO 100 - 1600 [ATTACH=CONFIG]135563._xfImport[/ATTACH][ATTACH=CONFIG]135564._xfImport[/ATTACH] ISO 100 - 3200 [ATTACH=CONFIG]135565._xfImport[/ATTACH][ATTACH=CONFIG]135566._xfImport[/ATTACH] I can push ISO down about three stops without much difference for the end result. That way I preserve my colors and DR better with a minimal price to pay. Only ISO 6400 I need to figure out the best method. But for the rest I only need 100-400 and I can shoot up to light levels requiring ISO 3200. If I shoot with auto-ISO set to max 400 and -3EV, I should have the best quality for those situations. If light is lower, I need to do something else. At 800 ISO all goes down too rapidly. [/QUOTE]
