The example picture illustrates the kind of effect that using crayon gives. Changing the pressure or size loses the impact of the crayon.
Sponge is a useful medium for covering large areas with an interesting texture. You can create nice clouds and landscapes using it. Also works just as well when used on a dark background.
The example shows sponge with the size set to 30, and pressure at 10%, then size kept the same but pressure set to 4%. Below it shows the size set to 50 with pressure at 4%, and next to it the size was kept the same but pressure increased to 10%.
Cloth is a nice media for covering large areas. Cloth is unusual in that its results can be changed drastically depending on whether you are in the dotted line mode or continuous line mode. In dotted mode you get the effect of dabbing a cloth over your image, and in continuous mode it has the effect of wiping a damp cloth with a little paint on it over the image. Unfortunately, cloth in continuous mode requires a very powerful machine such as an Amiga 4000/040, so by default it is set to dotted mode.
The first picture illustrates cloth in dotted line mode. Top left is with a size of 30 and pressure at 20%, then size kept the same but pressure reduced to 6%. Below it shows the size set to 100 and pressure to 6%, and then finally size set to 50 and pressure at 8%
The second example shows cloth in continuous line mode. On the left it has a size of 40, and a pressure of 3%, and below it with a size of 25 and a pressure of 3%. The effect on the left was achieved by going over an area several times but with the strokes in different directions.
This brush produces glowing strokes of light. It is most used for text or decoration, and works best with contrasting colours such as yellow on black or blue on white. Note that if you increase the size then you may wish to alter the pressure to keep the glow effect. The straight line draw mode works particularly well with neon.
