Tutorial images, and also images used for Contests get seen a lot more than images in threads.
Tutorials are often printed, and may get passed around outside the confines of RetouchPRO.
Contest images were planned to be used in the member's site.

Thus it is best if these more "visible" images have the proper consent.

Cooler still is that I'm posting this from Brazil (world hacker champs)

..and the blue cast, any takers?

This is where I'm pretty bad. How do you know it's got too much blue cast? I mean, I can see the photo is mostly bluish, but how does one know what the "correct" color balance is? Is there some rule you are following?

I was gonna take a shot at that one, but I looked at it for over an hour. I couldn't see anything wrong with it.

It's a pretty safe bet that the car is white, and not light blue. Also, the young lady (unless she is a parent of NancyJ) probably does not have blue skin.

To measure.
- Select the eye-dropper (<I>) and turn on the info palette (<F8>).
I find measuring colours in LAB to be much easier so I'll cite the numbers that way.
- For a white car the A and B numbers should be 0. Running the eye-dropper over the car, however, the numbers come out negative - B more so than A. B negative means Blue.
- Going over the young lady's skin (respectfully, of course ) we find that the B value is lower than the A value - for "normal" skin B would usually be 5 to 10 points higher than A.

The more difficult part is that the colour cast is not even, the dark parts have a higher cast.

To fix:
- Convert to LAB mode (of course? );
- Duplicate the layer and desaturate (<Ctrl><Shift><U>);
- Put in an eye-dropper point at the lightest part of the car, around 95%, and the darkest, 65%;
- Adjust using curves (or levels) the white point to 95% and black to 65%, invert (<Ctrl><I>) - this is now our mask for the colour fix. Turn this layer off (everything will be applied at 65% and nothing at 95%);
- Make a curves adjustment layer and Image>Apply Image.. to put the mask we just made into adjustment layer mask;
- Adjust the A and B curves until the eye-dropper point you set at 65% is reading 0 for both channels (95% already is 0)

All done - as a check the skin is now reading with B about 10 above A.

Mustang sally

Hi James.

Welcome to Retouch Pro.

Quite a strange fault on the film there. It looks like the film has torn.

Repaired the marks
Removed the blue from the mid-tones (This gave Sally a very tanned look but I decided to keep it)
Degrunged Sally only.
Sharpened

Oh. If only you had posted this earlier. I would have used her in the March Comp.
Maybe I would have had to let the tyres down.


Ed. So did I.

Here's the sky fixed. Twiddled with color balance to clear it up.
