A Painting Tutorial by Evelyne Schulz

Many months ago I discovered Evelyne Schulz on Twitter due to a GIMP-related post. I immediately loved her artwork and, after some correspondence, she graciously agreed to write a tutorial about how she creates her digital paintings in GIMP. What follows is what she wrote about how she created her Warrior painting, with editing and inclusion of a description of the Palette Editor by me.

How to Import EPS Files into Inkscape

While browsing the shelves of a local discount book store, I stumbled upon an interesting pattern book called Drip.Dot.Swirl. by Von Glitschka, published by HOW Books in 2009. Being a bit of a pattern nut and seeing a lot of patterns in the book that I liked, I was about to buy the book when I noticed that the DVD that was supposed to be in the back of the book was missing. The DVD contains editable vector files, swatch libraries, and tutorials and is at least half the reason for buying the book. Being undaunted, after a quick search online I found the book on amazon.com and had a copy in my hands within a week.

I happily popped the DVD into the drive and grabbed the first vector file, only to discover that all the files are in encapsulated PostScript (EPS) format and plain vanilla Inkscape is completely unable to load them. Fine. Back to the internet. After poking around for a while I finally found some useful instructions at InkscapeForum.com. Here's a quick step-by-step on how to set up Inkscape so that it can read EPS files.

Four Ways to Draw a Border Around a Selection in GIMP

I was recently asked for a quick way to draw a border three pixels wide around the inside edge of a rectangular selection on top of an in-progress graphic design. Two methods immediately came to mind and a third occurred to me later that afternoon. I discovered a fourth method while writing this article.

Method 1

The most obvious method to use is Select > Border [1], which opens the Border Selection dialog [2]. This dialog contains three adjustments.

Alignment and Distribution of Graphic Elements in Inkscape

Inkscape's alignment and distribution functionality is wonderful to use for organizing graphic or typographic design elements or laying out printed matter. In this tutorial I will demonstrate this by creating a simple graphic design of colored stars.

Alignment and Distribution of Graphic Elements in GIMP

When creating graphic or typographic designs or laying out printed matter such as brochures, leaflets, or newsletters, knowing how to use GIMP to organize and move graphic elements can be very handy. In this article I will explore GIMP's alignment and distribution functions by creating a simple graphic design of colored circles.

GIMP's Layer Modes (Somewhat) Demystified – Part 4: A Pictorial Comparison

For a final comparison among the layer modes, I created several examples that visually show the effects of combining various layers.

Grayscale on Grayscale

First, I created a square non-dithered grayscale linear gradient lower layer, then made a copy and rotated it 90º for the upper layer. I chose each layer mode to see the effect. Here's a visual representation of what occurs with each layer mode.

GIMP's Layer Modes (Somewhat) Demystified – Part 3: Grain Extract to Value

In this article I discuss the following layer modes: Grain Extract, Grain Merge, Divide, Hue, Saturation, Color, and Value. I will use the same test images I used for Part 1 and Part 2.

For each of the test images, I changed the layer mode of the upper layer to each mode and saved the result. I've included these images in each section below as references. What follows are my observations and thoughts about how to use each layer mode. Feel free to copy any of these images to your desktop so you can load them into GIMP for a closer look.

The layer modes are presented in the order in which they appear in the Mode drop-down menu. Here's a full list with quick links.

Dodge Hard Light Saturation
Addition Difference Color
