Hi
I'm trying to assess the nature of a colour cast which I see in an image and am trying to use the Image -> Adjustments -> Variations route in Photoshop CS2. However, I am finding that the Variations is greyed out and cannot be selected. Any ideas as to why this might be ?
Thanks !
Laura..... WHAT THE FOOK!!
Imagine the scenario here then... I take a photo of a blue sheep, which is sat on a big blue bouncy castle in the middle of the BLUE section of the Dulux factory...
...Then I follow your advice to correct a colour cast......
...again I ask......
....WHAT THE FOOK!!!
Much Love,

The man has a point....
The only way you can assess a colour-cast is in relation to an area that you wish to be a neutral grey. And the best way to do this is to look at the RGB values for that area in the info pallette. Only that way can you get a precise value on which to base your corrections. Looking at histos only tells you about the dominant colour, not whether it's a true representation of the scene or not.
Yeah fair enough, but generally want my shots to be netural with no colour casts, I understand if your taking pictures of something with a dominant colour, such as a blue sea and blue sky, the blue on the histogram will be the main colour, but sometimes its possible to do it by eye, I generally use a grey card to get a netural balance anyway.
This is probably heading the thread in a different direction, but I would appreciate any comments. I have recently been (lucky me) given an Epson 1290 A3 printer which had third party inks. There was a blue colour cast with rampant colours (orange and green predominantly) which I figured would be rectified by replacing with Epson inks. The blue (sky) is still purpler than blue and the orange which happens to be a pagan's face is now a flat orange.
Compared with the A4 print I did on a cheap HP printer, the Epson doesn't produce the goods.
On other prints, sky still prints purple and bright colours are more muted than the reality
Help please.
Best wishes
Mark
