You should be able to see a fishing line passing just over the heads
of the fisherman.

It's very clear, but is it just me, or does the photo have a blue cast
to it? Color is something I've always had some problem with, so I'm
curious what others think.

There is reflection of the greenery off the water which is making some
things a little on the yellow/green side, but there is nothing too
alarming.

I would make sure that there are good black and white points set. Then
tweak the WB, preferably with a good neutral grey target.

Fortunately that image is full of neutral grays. :-)

Regardless, it is a nice scene and the line is visible.

And the most succesful neutral gray that I eventually picked was the
gadget leaning to the right as though bracing something to the right
of the picture. It now has a yellow handle.

Hmmm..., I would probably have gone with the middle stripe of the
whiteish gizmo in front of the right side of the tent. The object on
the right of the image doesnt look close to neutral to me, it seems to
have a blueish tint.

I tried the 'whiteish gizmo' and finished up with yellow-blueish
what-not on the right. It all goes to show that choosing
colour-balance entails arbitrary decisions.

it did, leaning a little towards cyan.

Apart from anything else, I find LR's 'Vibrance' tends to
do that.

no it doesn't.

You will have to excuse me, but - I find LR's 'Vibrance' tends to

Here again is the original retitled -1.

Here I have found the only remotely gray pixel and used it to
rebalance the color:
https://dl.dropboxusercontent.com/u/...-7500487-2.jpg
The initial effect was to cause the two fishermen to fade into the
background so I have slightly tarted them up so as to make them a
little more visible.

I now have to say that the first image undoubtedly had an excessive
green tint. Apart from anything else, I find LR's 'Vibrance' tends to
do that.

Depending on the scene, I find that many times if I push "Vibrance" to
the right, I have to back off on "Saturation" a tad.

I have an almost absolute limit of 10 for saturation.

Isn't this stuff fun?

vibrance is a smart saturation control. it does not cause a colour cast.

More vibrance -- greenish tinge

Less vibrance -- tinge goes away.

Nothing else is being twiddled in the meantime.

vibrance is a smart saturation control. it does not cause a colour cast.

According to Jeff Schewe [The Digital Negative - p79]:

"Vibrance is a hybrid of a normal color saturation adjustment, but
it works in a nonlinear manner. Vibrance increases the saturation
of less-saturated colors more than really saturated colors. This
reduces the tendency for slamming highly saturated colors into
oversaturation. A negative Vibrance reduces saturation, but it
can't completely remove color to the point of being monochromatic
grayscale. It gives an old faded look, which can be useful.
Vibrance also is designed to respect skin color and avoid making
skin look too ruddy red in color."

So images full of unsaturated greenery will become more green if
vibrance is increased. The photographs under discussion were filled
with unsaturated greenery. The river reflected unsaturated green from
the trees. The trees cast an unsaturated green light on all around
them. Wind up the vibrance and up go all the greens.

the greenish tinge was there before.

nowhere does it say 'alter the colours towards green'.

try vibrance on a photo of a red flower or a blue car. it won't turn
things green.

So images full of unsaturated greenery will become more green if
vibrance is increased. The photographs under discussion were filled
with unsaturated greenery. The river reflected unsaturated green from
the trees. The trees cast an unsaturated green light on all around
them. Wind up the vibrance and up go all the greens.

in other words, the green was already there.

And turning up the vibrance will give (almost?) everything a green
tinge. I should have made clear I was talking about photographs of the
kind under discussion.

only what is already green.

if there was a red flower in the photo, it would not give it a green
tinge.
