Digital illustration

Drawing is an art form that involves the use of an instrument to mark a two dimensional surface. Artists have traditionally used analog media.

I studied science, so I drew fossils and on maps, and I learned programming. Then I got a pocket computer with a plotter. My first Mac had a graphical interface and printer. I now use digital tools to create images. So I work with digital art media (pen display, and mouse). Digital art requires creativity. My work is layered. First I used raster graphics software (MyPaint). Since when, I have been using the vector graphics application Inkscape. I'm in two art clubs.

Raster graphics

Pixels are tiny. They're arrayed. Forming a bitmap. Most Internet images are raster.

Clothed male portrait
This was in an art class at a community centre. The subject was an amiable cook.

Vector graphics

Vectors are scalable. They are visual elements. Geometry deals with figures. It has simple features. Points can extend into lines. Those can be curved. A polygon consists of joined lines. Maths defines those. Commands put them in space.

I entered the first two of these in an exhibition.

Self portrait
I finished my self portrait on Wednesday 1 May 2024.
Window frost
My digital media group had chosen the theme "frost". Therefore on Thursday 6 June 2024, I completed this project. The reference photo was from a Web site. I built up the image in many layers.
Cafe interior
Urban Sketchers Canberra visited the Canberra Museum & Gallery. I sat in its closed cafe, facing the bar. I finished this illustration on Friday 13 September, 2024.
Graffiti on the theme of deadlines
My digital media group had set the theme "Deadlines". On Friday 20 September 2024, I finished this conceptual artwork.
World Naked Bike Ride participant
My art group set the topic "Exhibition/Exhibitionism". My subject had been a local participant in the 2009 World Naked Bike Ride. I completed the work on Wednesday 6 November, 2024.
Scott's Crossing
On Sunday 12 January 2025, I was downtown. Urban Sketchers Canberra had a field excursion. The locale was Scott's Crossing. On 15 March 2025, this was my impression. My style is collage.
Diagram
I completed this on Saturday 5 April 2025. It shows how to connect a mouse to a TV.
Schrödinger's cat
My digital media group had chosen the theme "May...". Which I interpreted as "maybe". By Saturday 10 May 2025, I had depicted Schrödinger's cat.
Traced and filtered fossil leaves
My digital media group set the theme "lasting impressions". I auto-traced my photo of fossil leaves. They were late Permian, about 254 million years old. Then I added a sandy backdrop. And finally there's a filter-effect. I finished this on 8 June 2025.
Greyscale, RGB & CMYK gradients
I was impressed by a pastel demo. So I emulated such hues. Layering gradients. Those were radial and linear. The first being grey-scale. The others used colour models. Vertical was red, green, and blue (RGB). Horizontal was cyan, magenta, yellow and black (CMYK). I finished this on 16 January.
