Two girls sitting.

Not too obvious but evident in over rich

skin tones and over warm greys of pavement

background wall.

Investigation revealed that image had been

taken with WB set at 'Cloudy'. Problem was

 solved by changing WB in Raw to 'Daylight'

                                            First Correction

 Another method of correcting the same image

was achieved by using the WB tool and using

 the pavement as the reference.

                                          Second Correction

This is a more accurate rendering of the

original scene.

 

Entrance Hall. The image is too cold.

  

                                        Original

 

The image was changed 1) by using

Levels and adjusting Blue channel mid -

slide to 0.6 to obtain this version.

                                          First Correction

and 2) by opening Curves and using the

 grey dropper on the sleeve of grey coat.

                                         Second Correction








Although there is little difference between the Original and the Second Correction there is that degree of
 warmth that makes it preferable to the First Correction.

The original image is too warm. This is particularly
evident in the colour of the tarmac and tree foliage.


                                           Original Image

My initial attempt consisted of using the WB

dropper in Raw using the tarmac as the

reference. This produced an image that was

a little too cold. using the Temp slide I increased

the temperature from 4350k to 4800k.

This produced an image near to the original.

Summary: If possible I prefer to open the image in Raw. The WB dropper is a good start point for colour correction and the various other faclities available in Raw can be used for the finer adjustments.
