Inconsistent result

[ferlan]

I shot a wedding last weekend and just noticed there are some photos that have color banding and the metering was way underexposed, there are about 20 photos like this. At first i thought it was all because of the fluorescent lamp but then i checked the other photos on the same premises are fine.
Also there are 2 consecutive shots that kinda have different color profile, i think.
Please check the photos for reference, no editing at all just resizing.
I really appreciate all of your efforts and time to make this wonderful piece of engineering.

What camera is that? What ML you had onto it? What settings? Are you sure it's not user error?
What replies do you expect with this kind of post?
Color profile is never changed, as far as i know.
Also, i don't really see the color banding.

uhm what does the .CR2 say?
fluorescent lamps flicker with 100Hz, so it might still be because of the lamps flickering if your exposure time is < 1/200th.
at least the 3rd image looks like your lighting is the problem.

also check if you modified WB settings, but this doesnt sound like any ML problem or anything ML could help you with.

Thx for the reply mate, I just wanna find out if there's anyone out there has got the same result as mine. I shot jpeg AWB on 5Dii and didnt use any function in ML, just focus peaking which is only turned on in liveview mode. If it's caused by the lamps then I'd better be careful next time shooting in fluorescent ambient.
