This will remove a bluish tone of your digital images.
Many digital cameras take images with a slight blue cast.
The Remove Blue Cast has two sliders, one for images without flash used and the bottom one for images with flash. The sliders have no effect in the center. Right of the center it will remove Blue Cast, left of the center it will remove magenta cast (rare)
You should preview a couple of photos taken with flash and without and try to adjust both sliders so the image appear a bit warmer and a blue cast is removed (if any). Almost all digital cameras will have some degree of blue cast but it may not be apparent to untrained eye if viewed alone. However often a look on a Image Before and Image After will tell you if you have blue cast or not - the image will look brighter with better colors. The original image looks somehow washed with blue-like mist.
Correct setting of the Blue Cast Fix will make your images stand out. A colors will be suddenly more live and the image will gain in crispness.
Blue Cast Removal and Flash Images
On some cameras the blue cast is more visible on flash photos (Sony), some other cameras have flash photos actually with less cast than without flash (Canon). It all depends on the camera automatic white balance.

A typical settings for Canon S digital cameras. |

This settings is more typical for Sony digital cameras. |
The Blue cast removal for flash images uses a bit different procedure than without flash. Often the flash images have different type of "blue" cast, so the DCE address that.
| Blue Cast is one of the settings which highly depends on the camera model and your preferences. It is then worth to spend some time and preview both normal and flash images to figure out what setting suits you most. |
This will adjust the saturation. Some images may benefit from the enhanced Saturation.
The zero point is in the middle, to left images will be desaturated, to right images will have enhanced saturation. The DCE won't let you to over saturate the images so the slider doesn't have strong effect in the right (enhance).
Using this is more a personal preference. A little more saturation usually helps, but some may like the images saturated as they come from camera. Sony cameras usually have a bit more saturation directly from camera.
If you don't plan to use it, just switch it off (the check box in the header)
