I don't mean anything, but just saying that sometimes we are quick to judge people's pictures and tell them how it's supposed to look like when we were not even there to actually know how it looked like.
I don't mean you guys, but the comment reminded me of a post that I made at photo.net maybe a couple years ago, I was just posting something casual asking "When you take pictures, do you make them to look like how they are in real life, or do you make them to look 'right'?"
Meaning let's say if the actual picture is rather dark, do you expose until the picture looks 'right' as in normal, correctly exposed pictures, or do you leave your picture as how it looks like in real life - even if it means that it might look under exposed by people who don't know the actual story/condition behind the picture?
And I got sooo many condescending and arrogant replies, some of them said I should learn my craft agsain, some of them said something like: "We never take under exposed picture and all pictures we take were perfectly exposed...", bla bla bla... And one of the moderators replied to my thread in a very arrogant and condescending manner (can't remember what he exactly said) but it p|ssed the heck out of me.
So I went and checked his website. I found out that he makes a living taking pictures for small gigs and small sporting events, but that's what he is - taking pictures - no sense of art whatsoever. All of his supposedly 'best works' look at best only like snapshot style, all in B&W to give the sense of "pro" look but it was pretty crappy. And the guy had the nerve to talk as if he was the best photographer in the world. I gave him harsh replies (might've insulted his 'talent' too) but of course the other mods were quick in doing damage control and deleted his posts and mine.
Yeah enough rant about previous incident, but what I'm trying to say is, of course in certain situation it is easy to figure out how a picture is supposed to look like, but we can't really 100% tell how a picture is supposed to look like unless we are there.
Back to the example like the picture the OP posted, if in real life there was actually slight yellow tint there, I'd probably leave it as it is. It is just a normal shot, not a controlled studio portrait shot, so I tend to just leave things as natural as possible. But then again it might be just me though.
Well maybe his head is a bit yellowish in real life, who knows?
It's possible I guess. =)
I was thinking it was more likely due to the industrial lighting, and that a bit of white balance change or some slight color changing would improve the image.
