You're watching VisiHow. In this tutorial, we are going to show you how to apply a threshold to an object in GIMP in Windows 7.
You should have GIMP open and an image ready to use. You can refer to our other tutorials to find out exactly how to do that.
First, click "Colors" on the top-left side of the window.
Then, click "Threshold". A dialogue box will appear, and the preview will be updated.
Make sure that "Preview" is checked.
You can click the "Preset" drop-down menu to select a preset.
You can save a preset later by clicking the plus next to the drop-down menu. You can do it when you have finished adjusting your settings.
You can click or drag the triangle below the spectrum. Alternatively, type the values for the black and white levels. The left side is for a lighter spectrum. The right side is for a darker spectrum.
You can reset the changes by clicking "Reset".
Once you're satisfied, click "OK" to apply your changes.
