Using the Sample Colorize Function to Color an Image

You can find yet other methods to color an image in the Colors menu. These filters are found in the image window under Colors > Map. They allow you to colorize black-and-white images by mapping a color source image or a gradient from foreground and background colors. Therefore, you must first select both colors with the Color Picker from the Toolbox. We will have a closer look at the Sample Colorize filter. However, the Gradient Map filter (gradient from the foreground and background color) and, especially, the Alien Map filter offer some rather special effects.

When you select the Sample Colorize filter, a window opens that is split in two sections. On the left below Destination you can see what the image looks like after editing, and on the right below Sample the image is in the original condition. When you're editing, even color images are turned into black-and-white images and can only be colorized with one color or a gradient.

First, select the Get Sample Colors button to colorize an image. Then determine the sample color by double-clicking on the corresponding area in the image under Destination. You will have to determine yourself which area corresponds to the area with the desired color in the example image. The image in the preview is then colorized with the assigned color.

Below the two images are two color gradients with triangles that can be used as sliders. The sliders can be used as in the tonality correction. By moving the sliders, you can control the brightness, tonality, and intensity of the colors. If the color transition is too severe, check the Use subcolors and Smooth samples boxes.

When you are satisfied with the result, click on the Apply button. The applied filter settings will be transferred to the image.

In my experience, the program is rather instable; it crashed several times when I worked with a sample color from the image. However, colorizing with a gradient did work reliably. As previously mentioned, the program works with a gradient selected from the foreground and background color.

For this purpose, select the entry in the menu at the top right next to Sample. You may also select a reverse gradient. The image will be colorized instantaneously by the gradient. The gradient can be modified with the sliders below the preview images.

It could be interesting to deactivate the Hold intensity box. The intensity of the colors will be the same as the preselected colors in the gradient at first. But now you have complete freedom to change all settings. Go ahead and experiment with it.

Digital Cameras For Beginners

Although we usually tend to think of the digital camera as the best thing since sliced bread, there are both pros and cons with its use. Nothing is available on the market that does not have both a good and a bad side, but the key is to weigh the good against the bad in order to come up with the best of both worlds.
