[QUOTE="Nikonitus, post: 675195, member: 10962"] I have lots of troubles getting good results on overcast days which are those one colour full grey/white from wall to wall coverage, no feature or contrasting clouds,, just one shade. It's the kind of day that even with the naked eye, everything, even the brightest colours, look dull and lifeless. My photos also look dull and lifeless on days like this. I'm sure we all no that situation. I call them nightmare days.. Just yesterday I decided to buy a Sekonic L-478D light meter to try and help my settings etc, as it's still winter here and there are lots more nightmare days to come, I'm sure.. This morning I thought (just to pass a bit of time over these cooler days), I would begin to compile a database of days vs conditions vs lux readings. I know it won't be a short term project but I thought it would be the ideal time to get started.. On the L-478, is there a way to measure off lux readings "only"? I see you can add lux info in as an 'additional data' for each reading, but of course it changes each time you vary one of the eternal triangle (Aperture, ISO, Shutter) values, so it's only applicable to that particular reading. I want to meter existing lux only levels, on a daily basis from early morning, to midday, to nightfall, even night time etc in changeable conditions eg, clear blue sunny days, to cloudy/sunny, to overcast, fog and nightmare, to full storm etc,, as many varying conditions as nature can throw at me so I can make that database quite extensive.. I know there are existing sites with similar info but many of them seem very vague, with very rounded off info and even this morning while out there measuring (even with the other 3 settings), I've noticed some very large differences between what I can measure and calculate and what they say. I've skimmed over the L-478D user manual but that doesn't actually cover any "lux only" setting, although I may have missed it. I hate manuals... Any help is much appreciated... Nikonitus [/QUOTE]
