![]() ![]() Figure 8 shows a brightly colored variant, which was created by applying color filters to parts of the photo. Because there are no technical shortcomings to compensate for here, I will just play around with it instead. ![]() The lead image for this article does not require any rework in terms of exposure. If you want to make big adjustments to the color and brightness of an image, as well as adding layers, then Adobe Photoshop will have more tools available to do. Figure 7 shows the results and how to move the brightness zones. In the example image, it restores light conditions to match what is actually a sunny scene. In this way, you can redistribute light and shadows.Įxpanding the dark areas and highlights increases the contrast and adds a touch of sunshine to many a gloomy, rainy image. You can use the slider to move the edge of the gray field and increase (by dragging to the right) or reduce (by dragging to the left) the brightness of the corresponding image areas. If you move the mouse to the bottom edge of one of the zone boundaries, a slider appears. If you mouse over a zone, any areas in the image with that brightness level light up in yellow in the thumbnail in the panel.įigure 7: The sun is shining: The zone system influences light and shadows in the image in a granular way, which is far more appropriate for sunny surroundings in this example image. It divides the brightness spectrum into nine zones which the gray wedge symbolizes. To spice up overly gray photos, the zone system tool ( Figure 7) under the tone group toggle is a big help. The image now appears to have a more balanced exposure however, it also seems flat and has little contrast. In other words, if you drag a control point from deep green toward orange, as shown in the picture, you are modifying the green tones in the image accordingly.Īs so often happens in image editing, the best results can occur when trying things out – and, as always in Darktable, a double-click will reset the curve. The effect of the third tab hue is a little more difficult to understand: Moving the control points causes a color transformation from the color square where the shift starts to the color square where it ends ( Figure 6, right inset). The curve superimposed from the saturation tab shows the section of the spectrum that was already used in desaturation. ![]() You can also reduce the lightness of the greens in the same color range. Figure 6: You can get rid of the annoying green color cast under the leaf canopy using the color zones tool. ![]()
