Erasers

When it is necessary to erase parts of a picture it is often better to change the Method to Erasers in order to retain the same brush stroke characteristics. There are times however when it is more convenient to use the Erasers in this category as you can then swap very easily between the cloning brush and the eraser.

There are several brushes that have uses other than as erasers. The darkener can be used to enhance modelling by darkening shadows.

The Gentle Bleach will do the opposite and brighten areas. When used with large brush sizes and a low opacity many erasers will lighten or darken whole areas.

Eraser Painting

The photograph of this rather grotesque statue was taken on a very dull overcast day and the resulting picture was lacking in contrast.

Two of the Eraser brushes were used to improve the contrast and brightness.

The Darkener was used to paint in the background to remove the bright areas, then the Gentle Bleach to paint over the eyes and areas where the light would be expected to fall.

Various brush sizes and opacities were used and alternated until the picture was complete.

The name F - X immediately tells us that this group of brushes is intended for special effects. Some of the brushes such as Graphic Paintbrush, Furry Brush and Piano Keys will also work well as cloners, they will all produce some very unusual pictures.

Other brushes work directly upon the picture. In the examples below Glow, for instance, lights up the headlights of the car, while Fire seems to set light to it.

Shattered imposes a broken structure over the original as though it is being seen through broken glass. The Furry Brush and Hair Spray both use the airbrush effect and shoot out the paint in the direction that the stylus is angled.

The examples above show how brushes in this category may be used to create unusual abstract pictures. Figure 3.50 used the Shattered brush initially then the Fairy Dust brush added the stars over the top of the picture.
