Painter IX Newsletter, The Painter Canvas'
January 2007 Featured Tutorial


I hope you're enjoying the January 2007 issue of The Painter Canvas and found my tutorial, "Corel Painter's Set Paper Color Command, Eraser's Eraser, and the new Painter IX.5 Eraser Tool" helpful and informative.

As promised, below are additional notes related to the tutorial.

Leading Image

The first image at the beginning of the tutorial I named "Erase to the other side of the world" for a reason you might not guess (or you might). The process of erasing down through paint or filled color on the Canvas and through multiple levels of new base Canvas color has always reminded me of something from childhood. That is, the idea we could go out into our back yard and "dig a hole to all the way to China". Of course not everyone lives on the opposite side of the world from China and I've learned more recently we in the U.S. don't either. In fact (so I've read, lacking a globe to check), if we were able to dig a hole all the way through the earth, we'd arrive somewhere in the Indian Ocean. Thus it seems quite appropriate to be facing the sky when digging (or erasing) all the way to the other side of the world, no matter where we happen to live. Wishing you sunny skies the next time you start digging!

The image was created using the following steps:



1. Opened a 650 x 650 pixel, 300 ppi white Canvas.

2. Chose a green Gradient (don't recall which one now), and used one of David Gell's Suminigashi Grad variants, set to the largest size my system can manage, about 310.

3. Painted across the Canvas to fill it with softly varying shades of green mixed with white from the Canvas, the brush dragged along in the stroke.

4. Created a new Layer, and in the Selection Portfolio, chose the Spiral selection, then dragged it onto the Layer.




5. Many times, picking appropriate colors from the painted Canvas, I used the Set Paper Color command, then painted with the new Eraser tool to expose each new color (new base Canvas color) until I had a colored spiral starting with a lighter green at the outside and ending with a dark green at the center.

6. Next, I created another Layer and used the Oval Selection tool to draw a circle in the center of the spiral.

7. Used the Set Paper Color command to change the new base Canvas color to blue, then erased with the new Eraser tool to expose the circle of blue.

8. Last, I used the Set Paper Color command to change the new base Canvas color to white, then erased to create a tiny cloud.




There certainly are are faster ways to create an image like this but it was a fun experiment and seemed appropriate when creating the leading image for this tutorial. I expect we can find ways to use the technique again sometime (but probably not for a whole image!).

Eraser's Eraser Variant - Other Subcatgegory Options and How They Work

When we choose the Eraser's Eraser Variant, restore it to its default settings (Brush Selector menu > Restore Default Variant), then open the Brush Controls' General palette, we'll see the Subcategory is Soft Paper Color.

At the bottom of Step 5 in my tutorial,
I said: "Other Subcategory options would make this brush variant behave differently. Try them sometime to see how (but not now.. we still have work to do)."

Now I'll share what I've learned about how the other Subcategory options make this brush variant behave. It may not be everything you'll want to learn since I haven't used them much myself (except tonight while writing this information for you) but this should get you started:

The Erasers' Eraser variant when set to use these other Subcategories, will not work on Watercolor Layers, Liquid Ink Layers, and on wet Digital Watercolor paint. There may be some other scenarios in which these Subcategories won't work but in most cases, they should.

Soft Paint Remover
  • Erases added color (either painted or filled) on the Canvas but does not erase below the Canvas color to a new base Canvas color we may have set using the Set Paper Color command.
  • Erases either painted or filled color on a Layer but does not erase to reveal Layer transparency. When we erase on a painted or color-filled Layer with the Erasers' Eraser variant set to Subcategory: Soft Paint Remover, the result is white where we erased, even though the Layer was transparent before painting or filling that area with color.


Soft Paint Thickener
  • On the Canvas - Darkens the Canvas color or added color (either painted or filled). Use at low Opacity, starting with about 10%, then experiment, to avoid getting black at the default Opacity setting, 100%.
  • On a Layer - Darkens painted or filled areas of color. Use at low Opacity, starting with about 10%, then experiment, to avoid getting black at the default Opacity setting, 100%.
  • When used on white the Eraser's Eraser set to Soft Paint Thickener has no effect.


Soft Alpha Colorize
  • On the Canvas - When used on the Canvas color or added color (either painted or filled), the Erasers' Eraser variant set to Subcatgegory: Soft Apha Colorize applies the Main Color.
  • On a Layer filled with white, or other color, the Erasers' Eraser variant set to Subcategory: Soft Alpha Colorize applies the Additional Color.


Soft Grain Colorize
  • On either the Canvas or a Layer - When used over the Canvas color or other color (either painted or filled), or color on a Layer, the Erasers' Eraser variant set to Subcategory: Soft Grain Colorize interacts with the currently selected Paper. Depending on which of two colors, Main Color or Additional Color, is in front, color is applied either in the lower areas or higher areas of the Paper. It works similarly if, instead of reversing Main Color and Additional Color, we click the Papers palette's Invert box to invert the Paper texture.
