I took a stroll down at the beach today and was dumbfounded by the bright colors... Cross my cold, dark heart: There's no post-processing hooey going on here:

A car drove by during this one and its headlight nicely added some diversity to the grass. Sometimes they help.

This is interesting. I have been taking two variations tonight to check the differences. The previous was 400 ISO, the next 100 ISO. Both are processed identical besides the 100 ISO being normalized to the same exposure as the other. I noticed I touched the aperture again. Darn gloves but that's a minimal difference there.

I don't really understand why my WB is so different while the shots are identical except the ISO. I checked the others and the same happens there. 100 ISO is a lot warmer than 400 ISO.

That is pretty amazing. When you find out why be sure to share it with the rest of us

I need to find out for sure. I can normalize the WB and in that push the tones back to their original colors but I'd still like to know why this happens. During the daytime my WB is pretty good but what happens at night is strange at the least.

I don't really find information about a possible connection between ISO and WB. Another answer might be that any WB setting is applied after the shot and as such, when using auto, will vary depending the color intensity or brightness of the shot. My 400 ISO is cooled down while my 100 ISO gets warmed up.

I've been looking into this some more and still can't find a decent explanation for the rather drastic temperature difference between 100 and 400 ISO. One could assume that if auto-WB is applied depending the values of the captured shot, the 400 being 2 stops "brighter" than the 100 would be processed warmer. Yet strangely it is the more exposed that is cooled down to 3.5k while the least exposed is processed with a daylight temperature.

The cool blue/purple 400 ISO is closest to what I observed before taking the shot. One could say that matches reality. However, and now it gets really funky, there is such a thing like the Purkinje effect; during low illumination the sensitivity of the human eye shifts towards the blue end of the color spectrum.

So either the 400 is correct because it matches what I observed, or the 100 is correct because it matches what was truly there to be observed. In the end, I will never know which of both is accurate.

Ain't that funny.

Well maybe not that funny. We need our experts on high tech to weigh in on this. Something going on. Can you shift them both in pp to look like each other?
