I'm not real happy with my Plus camera's reactions to different light conditions.
Not only does it do some weird, indecisive and rapid exposure compensation flickering as it sees 'slightly' different light conditions, there is also a patch of significant focus 'and' color shift as it follows it's own shadow across the ground, which is especially noticeable when pointing straight down, and is absolutely horrible.
This is most pronounced on vegetation ...... like brush, trees and grass for some reason.
It's evidently having problems making a decision on what exposure to use when it follows a dark object moving across the image (I.E. it's own shadow) which causes that area of the image to go out of focus and shift color/tint.
Curiously this does not seem to happen when it moves across a dark area in the frame .... only when it's following something dark moving against a light background.
Although YouTube seems to amplify this effect, I also see it when playing the viddys on my PC and TV off the SD card.
I tried different exposure settings, with little change to this effect.
So ... I started to look at different peoples' Plus viddys on Vimeo and YouTube.
'All' the viddys have the same rapid/flickering light exposure changes as the frame goes through even just 'slightly' different light conditions, but to different degrees with different cameras, under similar light situations.
They all also have the same patch of area that goes in and out of focus and changes color/tint, that follows the dark shadow of the Plus when it moves across a light background .... with the degree of that being both different between ..... say ..... light dirt, pavement or concrete and green brush/trees/grass ...... with it showing up more against vegetation.
And this effect is (once again) significantly different amongst the different viddys with similar content, under similar light changing conditions.
Here is a viddy of my Plus showing both the change of focus/color that follows the Plus' shadow (upper right in the frame) as it moves across vegetation, and the rapid flickering from mildly changing light to dark backgrounds of the sky, towards the end of the viddy.

When looking look at other people's Plus viddys on YouTube/Vimeo the same thing happens in similar conditions, albeit to slightly different degrees.
I'm going to mess with the camera settings, as it does make a 'bit' of a difference when gong from things like 'center' to 'average' exposure, as did going from 'auto' to '60Hz' anti-flicker.
