Blend tools can be considered gradient tools in GIMP, allowing you to blend more than two colors to get exciting color mesh up for different purposes. In previous versions of GIMP software, you will find this tool named Blend tool in the tool panel, but in the latest version that is We can also use the Blend tool in the blending of two images with each other. Today in this article, we will discuss different parameters of this tool and get knowledge about how we can edit it as per our requirement.
We can use the blend tool in many ways, such as we can make a nice color blended background, blend two images for their manipulating purpose, and some other things. So let us understand the working of this software through some examples.

Click on the New option of the scroll-down list. In the dialog box of creating documents, you will have different preset sizes. You can choose any one of them. Or you can enter your own value of document size. This will gather all of your windows back into a single window, and your Toolbox window will no longer be missing or detached.

Although this tool is not present in the Toolbox by default please refer to Section 1. This area appears as a more or less enlarged square when you maintain the click on a pixel.
The white slider has been moved to the start of well marked Highlights. The image lightens up. The resulting histogram down shows Highlights now, but Shadows are still predominant.
Setting the balance between Shadows and Highlights. The mid slider has been moved to the left. This results in reducing the proportion of Shadows and increasing the proportion of Highlights.
Levels 8. Activating the Tool. Level tool options. Channel You can select the specific channel which will be modified by the tool: Value makes changes to the value of all RGB channels in the image: the image becomes darker or lighter. Remember that adding or removing a color result in removing or adding the complementary color Alpha works on semi-transparent layers or selections: here, dark means more transparency, and white is fully opaque.
Three numeric text boxes to enter values directly. Original image. Black slider has been moved. White slider has been moved. Original image a gradient. Example for Levels eye-droppers Above is original gradient from black to white. Tool Options dialog. Actual practice. Prior to blending, images have gamma correction removed and are converted from sRGB to linear.
After blending, they are converted back from linear to sRGB. However, before converting back to sRGB, opacity is applied. Figure 8. Images backgrounds for layer mode examples. In the descriptions of the layer modes below, the equations are also shown. This is for those who are curious about the mathematics of the layer modes. You do not need to understand the equations in order to use the layer modes effectively, however. Unless the description below says otherwise, a negative color component is set to 0 and a color component larger than is set to Since the results of each mode vary greatly depending upon the colors on the layers, these images can only give you a general idea of how the modes work.
You are encouraged to try them out yourself. You might start with two similar layers, where one is a copy of the other, but slightly modified by being blurred, moved, rotated, scaled, color-inverted, etc. Most other modes are rather cancellation modes.
Both images are blended into each other with the same intensity. Normal mode is the default layer mode. The layer on top covers the layers below it. If you want to see anything below the top layer when you use this mode, the layer must have some transparent areas.
Equation 8. Dissolve mode dissolves the upper layer into the layer beneath it by drawing a random pattern of pixels in areas of partial transparency. It is useful as a layer mode, but it is also often useful as a painting mode. This is especially visible along the edges within an image.
It is easiest to see in an enlarged screenshot. Lighten only mode compares each component of each pixel in the upper layer with the corresponding one in the lower layer and uses the larger value in the resulting image. Completely black layers have no effect on the final image and completely white layers result in a white image.
Screen mode inverts the values of each of the visible pixels in the two layers of the image. That is, it subtracts each of them from
