Usage Tip #2

You can use Split Channel mode and the the Assign Original Image Color slider to add interesting texture to an image.

The intensity information in each RGB channel contributes 1/3 of the intensity to the overall image. If you alter the intensity information in each RGB Channel using Split Channel mode in Lucis and also move the Assign Original Image Color slider to 100% Original then the color shifts are removed and the image just has the altered contrasts.

In this example I will use Split Channel mode to enhance the Red Channel, then enhance the Blue Channel the same amount, and then drastically enhance the contrasts in the Green Channel so there is an interesting texture added to the image.

To start I opened the image in Photoshop and duplicated it on a layer. (Click here to download the full original image (5.4 MB jpg image).I selected the duplicate layer and opened Lucis Pro. I checked Split Channels (to enter Split Channel mode) and unchecked Display Composite Image (so I could view the intensity information in each RGB channel). First I enhanced the intensity information in the Red and Blue Channels so the texture in the Green Channel will not overwhelm the image details. I selected the Red Channel and moved the Enhance detail slider to 145. I selected the Blue Channel and moved the Enhance Detail slider to 145. I selected the Green Channel and moved the Enhance Detail slider to 17 and the Smooth Detail slider to 11. The grayscale image in the green Channel was very patterned but this effect will be reduced by 2/3 when I look at the composite image. Lucis Pro UI screen shots below.

	To the left is the grayscale information in the Blue Channel of the original image.
	To the left is the grayscale information in the Blue Channel with the Enhance Detail slider set to 145.
	To the left is the grayscale information in the Green Channel of the original image.
	To the left is the grayscale information in the Green Channel with the Enhance Detail slider set to 17 and the Smooth Detail slider set to 11. This image is very patterned.

Next check the Display Composite Image. The colors are wild. The Lucis UI image is below.

Next I moved the Assign Original Image Color slider to 100% Original to remove the color shifts. The Lucis UI image is below.

Finally to reduce the effect of the Lucis-processing I mixed in 50% of the original image using the Mix With Original slider. The Lucis UI image is below.

As a last step I used Level Adjust in Photoshop to make the image just slightly darker. A comparison of the original and final Lucis-processed images are below. High resolution images are available for you to download and examine. Also note that I had chosen to 1) enhance the Red and Green Channels the same amount and drastically enhance the Blue Channel or 2) enhance the Green and Blue Channels the same amount and drastically enhance the Red Channel then very different images would have resulted. It is worth experimenting with this technique. I tried all these combinations and liked the effect of drastically enhancing the Green Channel best.
