Adjusting the brightness of an image in GIMP is a simple process that can help you enhance the overall quality of your photos or make them appear more dramatic. Here are the steps to adjust the brightness in GIMP:

1. Open the image you want to adjust in GIMP.
2. Go to the "Colors" menu located on the top menu bar and select "Brightness-Contrast."
3. In the "Brightness-Contrast" dialog box, you will see two sliders: one for brightness and the other for contrast.
4. To adjust the brightness of the image, move the "Brightness" slider to the right to increase brightness or to the left to decrease it. You can also type a value in the "Brightness" field to adjust the brightness level precisely.
5. As you adjust the brightness, you can preview the changes in real-time by checking the "Preview" option.
6. Once you are satisfied with the brightness, click the "OK" button to apply the changes to the image.

Alternatively, you can also adjust the brightness of an image using the "Levels" tool. Here's how to do it:

1. Go to the "Colors" menu and select "Levels."
2. In the "Levels" dialog box, you will see a histogram of the image's tonal values, along with three sliders: one for shadows, one for midtones, and one for highlights.
3. To adjust the brightness of the image, move the midtones slider to the right to increase brightness or to the left to decrease it.
4. As you adjust the slider, you can see the changes in real-time by checking the "Preview" option.
5. Once you are satisfied with the brightness, click the "OK" button to apply the changes to the image.
