Problem : Solution Correct color casts

Problem: Unwanted color casts in an image.

Solution: Use the Photo Filter command.

The photo Filter command is designed to correct common color balance problems you quickly as well as help you easily add a warning or cooling effect to your images.Once you learn how to use it,you'll find it to be a perfect way to control color casts, whether you want to add them or get rid of them.


A simplified dialog box makes it easy

1.

Open an RGB or CMYK image.

2.

Create a Photo Filter adjustment layer by clicking the Create New Fill Or Adjustment Layer button on the Layers palette and selecting Photo Filter from the dropdown list. The Photo Filter dialog box appears.

Adding a color filter

1.

Select a preset hue adjustment from the Filter dropdown list or select the Color option button to apply a custom color filter. Clicking on the color swatch to the right of the Color option button displays the standard Color Picker dialog box, where you can choose a color by clicking on the picker or entering the desired values for the color space of your choice. Whether you choose a preset or define your own color, the Density slider determines the amount of color you apply to the image.

2.

Make sure the Preview check box is selected as you experiment with the slider so you can see your changes on the fly.

3.

Select the Preserve Luminosity check box. Luminosity maintains the tonal balance of an image, which means the highlights, shadows, and midtones maintain their relative values to one another. The alternative (with Preserve Luminosity deselected) is to apply a flat color overall and, in the process, lose the range of tone or contrast that already exists in the image. Unless you're purposely attempting a flat effect, it's preferable to maintain luminosity in an image.

Easily fix the most common color problems

The Photo Filter command is designed to correct common color balance problems quickly as well as help you easily add a warming or cooling effect to your images. Once you learn how to use it, you'll find it to be a perfect way to control color casts, whether you want to add them or get rid of them. The first four options in the Filter dropdown list are the warming and cooling filters, which are designed to compensate or re-create color tints caused by ambient lighting conditions. The warming filters shift the colors of an image toward yellow to compensate for an abundance of blue, as shown in our Problem image. Cooling filters shift every color in an image toward blue. The Warming Filter (85) and Cooling Filter (80) seem to apply their adjustments to the white balance, while Warming Filter (81) and Cooling Filter (82) make minor adjustments to the overall color quality of an image. For example, you may find that using Cooling Filter (80) doesn't have an adequate effect on the shadows or midtones. In that case, the color quality filters (81 or 82) might be the better choice. As always, experiment with various filter and density combinations to find the ideal settings for your image.

Better color in less time

The Photo Filter provides an easy tool for working with color balance. In general, you can enhance color casts in an image by choosing a similar color filter or you can lessen a color cast by choosing a filter of a complementary color. It won't replace your regular suite of color-correction tools, but it's great for quick color shifts and special effects.
