Images are not that perfect, but graphics world does not have a room for imperfections. So, computer graphics programs have tried and are still trying to create special tools that will help users in editing their work.

Image imperfections refer to flaws, such as blemishes, scratches and other unwanted spots. These are things that you would not want your image to have. You would probably resort to editing tools.

One of most widely used tools to fix such problem is Clone tool. Clone tool takes pixel of sample area onto part or flaw that you are correcting. Sample area, by way, refers to that part that you want to replace flaw with. For example, you want to correct your own photograph because it has dark spots on right cheek. You can use other cheek as a sample area. It’s like copying left cheek and pasting it on right cheek to cover spots. Clone tool, however, has a drawback. Clone area is easy to spot because, sometimes, color of sample area and area around flaw does not match. This can also happen even if they have same texture.

According to designer, what is exciting about using computers is that artists and designers like him are now able to fuse present technology with traditional art. They are able to do things that used to be done in traditional art, but much faster and less waste with onset of digital technology. This is due to fact that designers are able to change and edit illustrations and ideas even if it's already at final stage of project. Even with changes, result of project rarely differs from original thrust and objective.

Stage 1: Sketch and Digitization Sketching and digitization are almost same in both traditional art and digital technology. In traditional art, an artist usually starts by making a sketch on paper. With Photoshop's graphic palette, it nearly replicates same feeling. Nevertheless, designer is quick to add that shaping a drawing on paper is still faster and more intuitive than doing it on computer. Although he also admits that even if basic drawing is done on paper, computer techniques can produce interesting effects such as halftones that are otherwise not available with drawing pencils.

Stage 2: Preparing Layers After importing sketch into Photoshop, image should be converted to sepia tones before working on color. To convert to sepia, go to Image > Adjustments > Hue/Saturation, check Colorize box, and use sliders to colorize lines into brown, reddish ochre, or yellow. This method provides a silkiness feel to line. In sepia, lines of sketch yield halftones that are more delicate, resulting to an image that is easier to view but retain its basic structure.

The designer suggests adding colors that do not compete with lines in drawing. This may weaken lines from original sketch. At same time, sketch should not also overpower colors. In effect, designers should blend two elements to find right balance.

On choice of sepia, designers should look at technical rather than aesthetic considerations. Brown tones result from a mixing of all colors, so when picture is colored, paint colors will blend more easily with lines. However, using sepia is not an absolute rule, although it does provide softness in drawing while preserving its descriptive character.
