I am working on lesson 8 on the Lynda.com Photoshop video lessons, and it deals with Balancing Colors.
Correcting a Color Cast Automatically
I started by selecting the eyedropper tool to be able to find the Hue and saturation of certain parts of the photo. I then went to the image menu and selected Auto color.
Manually Adjusting Colors with Color Balance
I went and selected the eyedropper tool again. The backgrounds hue was jumping around so I created a new layer and named it balance.
Then I opened the Properties panel, I changed the Midtones Cyan-Red to -40, Magenta-Green to -20, and Yellow-Blue to 20. On the Shadows tones I changed Magenta-Green to 20, and Yellow-Blue to -5. On the Highlights I changed Yellow-Blue to 30.
Tipping a Color Cast with Photo Filter
I went to the Adjustments panel and chose Photo Filter by alt clicking and created a new layer called balance 2. Then I changed Warming Filter (85) to Cooling Filter (LBB) and selected the color on and clicked the color swatch next to it.
I changed the Hue to 264 and the saturation to 11% and clicked OK. I changed the density value to 70. I then turned the balance layer on and clicked on it to make it active.
I wiped the Midtone values back to 0.
Correcting Color Cast in Camera Raw
I first went to the Filter menu and chose Camera Raw Filter. Which brung up the Camera Raw Interface.
I then used the white balance eyedropper tool and it automatically changed the Temperature to +23 and the Tint +73 but then I changed those to +20 and _70 and pressed OK.
I went to the yellow turtle again and went to the Layer menu and clicked Flatten Image and then went to the Filter menu and clicked Camera Raw Filter.
I then used the white balance tool again and set the Temperature values to -7 and Tint to +31 and clicked OK.
