Color cast options
You can use the options in the Color cast section to remove an unwanted hue from an image.
To use the Color cast options:
1 Click an image area that should be white or gray. The color square shows the color of the original
pixel on the left, and of the modified pixel on the right.
2 Select one of the following White Point correction color cast options:
• Custom: Displays the color temperature of the area in the image that you clicked.
• Sunny: Adjusts the color temperature to 5500K, approximately that of the midday sun.
• Cloudy: Adjusts the color temperature to 6500K, approximately that of a lightly overcast sky.
• Shade: Adjusts the color temperature to 7500K, approximately that of a heavily overcast sky.
• Tungsten: Adjusts the color temperature to 2850K, approximately that of a household light
bulb.
• Fluorescent: Adjusts the color temperature to 3800K, approximately that of a fluorescent
light bulb.
• Flash: Adjusts the color temperature to 5500K, approximately that of a camera flash.
3Drag the Strength slider to specify the color cast removal strength. Higher settings remove more
of the unwanted color.
4Drag the Temperature slider to select a specific color temperature.
Resampling
method
Use this option to determine the method used to resize (resample) the image:
• Box: Displays considerable tiling or jaggies when you resize an image.
• Triangle: Produces good results for image reduction and enlargement,
but displays sharp transition lines.
• Bicubic: Produces good results with photo-realistic images and with
images that are irregular or complex. Uses interpolation to minimize the
raggedness normally associated with image expansion.
• Bell: Smooths the image.
• B-spline: Produces smooth transitions, but may cause excessive blurring.
• Lanczos: Produces the sharpest images, but may also introduce some
ringing artifacts.
• Mitchell: Produces smooth transitions when enlarging photo-realistic
images. This filter is good compromise between the ringing effect of
Lanczos and the blurring effect of other filters.
• ClearIQZ: Slower than Bicubic and Lanczos, but produces the best results.
