When you take a photo of a traditional drawing, or when you scan it, it is possible that there is a noticeable loss of dark tones. There are probably many reasons for that, and it is possibly a feature of scanners and cameras not a defect. Regardless of why they end up losing the dark tones, it takes part of the beauty of most traditional pencil drawings. Luckily, there are ways to bring those darker tones back.One of these ways being using an image editor to manipulate the contrast of the drawing. For this tutorial I will be using the GNU Not Unix Image Manipulation Program, also known as GIMP. Which is free and open source. However, it is important to note that manipulating contrast is one of the most basic features in photo manipulation software. You can use this tutorial to achieve the same result using Adobe Photoshop for example.
