Hi Ali,

I have noticed that some of the time your pictures have some amount of CYAN cast

1 ) I have duplicated the layer
changed the mode to SOFT LIGHT - opacity 18 %
increased little bit Red
increased Sharpness with High pass. 0.08

I quickly white-balanced the shot, using the white centre of the front wheel - it was a little too cool, and there was a hint of green cast.

Hi Colin,

Your findings Is from my corrected Image or from Ali's posted Image.

I may be wrong, but I take it from the face or say skin colour.

According to my judgement, Image posted by Ali is having highlight portion with little Cyan cast

Green cast that means to neautralize green you have to increase Magenta

Our beautiful grandaughter Abigail having a great time at Easter. Might not be the best technically but I love the expression on her face. ...

And you are absolutely right

[Antonio Correia]

... Sorry Antonio, we might hack this bit out if it goes on too long.

No, please don't ! It is part of the business. Don't go away. It adds value t this thread !

You are most welcome ( As always )

[Antonio Correia]

It lowers the effective resolution, but ... RAW capture (ie no changes due to JPEG processing), but an increased transfer time ... so I'm between a rock and a hard place at the moment until LR3 goes RTM.

Thank you Colin for your excellent contribution

And you are absolutely right

What? That it's not the best technically

[Antonio Correia]

I am enjoying this conversation very much! Thought I let you guys know ...

Nice as always Alis
My un-trained eye doesn't see those casts.
Poor me

He is driving in the right direction, the concrete board is "running" to the left, the background is blurred... he is looking ahead... It all contributes to a good image.

The value of images in not only measured for being technically perfect, is it ?

Hi Colin,

I used Ali's image.

When I used the whitebalance eyedropper on the front wheel it added "+3" on the tint (green/magenta axis) so it thought that there was a slight green cast, but +3 is "noticeable, but only just". On the other hand, it added +12 on the blue/yellow axis, suggesting that the the main issue was the colour temp being set too cold (if you look closely at the skin tones and wheel you can see the blue). All looked good from my end when I applied the correction.

Hi Colin,

( BLUE - GREEN makes CYAN ) You are going methodologically while I rely on on my eyes that is the difference..

[Colin Southern]

Hi Colin,

( BLUE - GREEN makes CYAN )

Yes, but the image required different amounts od each

[Ashwin]

Yes, but the image required different amounts od each

Yes you are right
Your method pin points exact amount
while in my way of doing, I constantly have to look on Image while applying any correction

In both case end result has very little difference

[Alis]

Thanks, Ashwin, Colin, and Antonio!

Nice correction. I am not that sensitive to these when I do it but then when I compare the corrected version with my own, I clearly see the difference. Antonio thinks he has the same problem but I see his pictures are always spot on in terms of colors, but then I am no sensitive myself

Just so you guys know, I really enjoy seeing a colors comes out as close to what I saw in the outside world as possible. But I always have difficulty getting that.

Colin, in the book you once recommended, "Skin", I remember there was a rule about the combination of RBG by percentage for skin tones of different races. I have to borrow the book again and read that part. Once I went by that and the skin looked very nice and real (it something like Red is always twice as blue and green by percentage, or something close to this).

Thanks again!

[Alis]

I don't have to worry about white balance with this one

Hi Ali,

I can't remember the ratios off the top of my head, but I know the section you mean. My personal experience is that adjusting skin tones visually usually produces considerably less accurate results than white balancing off a gray card (or some other neutral reference); I only tweak visually on rare occasions (and even then it's more to correct for a slightly off printer profile than anything else).

Hmmm - 2nd time you've posted a photo of this person ... it's not one where your son has turned the camera on YOU is it?

Yeah, it was a shoot out...
