Beetle Week Day 2: Painting Bugs with ArtRage Studio Pro

Welcome to Day 2 of Beetle Week!

Earlier this year I was commissioned by entomologist and insect photographer Morgan Jackson of Biodiversity in Focus to contribute to a soon-to-be-published, honest-to-gosh dead-tree book about jewel beetles in Ontario. The result? My first series of scientific illustrations, instead of the off-kilter, surreal science paintings I'm known for. 

Today: Painting Bugs with ArtRage Studio Pro

When tackling a new illustration subject for the first time, I like to begin with mechanical pencil and bristol paper. They're my comfort zone. After that though, I have decisions to make. In my undergraduate degree, I worked mainly in oil paint. Since then, I sometimes find it more useful to paint digitally, especially for a project like these beetles. Adjustments and corrections to ensure scientific accuracy are much easier with digital media than with traditional paints.

I've tried a number of digital painting programs, and by far my favourite is ArtRage. If you're not familiar, it's a digital painting program with versions available for PC, Mac, iPad and the iPhone. Each one is relatively affordable (under $100 for the PC version, compared to several hundred for Photoshop).

The main attraction for me with this program has always been the interface. Instead of drop-down menus, ArtRage includes all the important tools right on the screen in two quarter-circles in the corners:

On the left, all your tools: oil and watercolour brushes, inking pens, pencils, erasers and host of other tools from technical to goofy. On the right, the colours, allowing you to adjust tones and how metallic the paint appears. These two palettes, tools and colours, mean everything to me as a classically-taught painter. I feel just like I'm dipping into my palette or brush box.

In ArtRage you can control the paper or canvas surface (or blackboard, or sandpaper or...) and the digital paint handles differently on each type. The big advance in Studio Pro (also known as ArtRage 3) over the previous 2.5 version is, in my opinion, the amazingly realistic watercolours.

I planned to use watercolours for the beetles early on. It can give the work the feel of old naturalist's studies. However, as the project went on, I realized that more than watercolour would be needed to bring out the richness of texture and metallic colour on some of these little animals.

Here's a look at Xenorhipus:

This painting required a lot of stippling.  The Intuos 3 graphics tablet has 1024 levels of pressure, so you can achieve some subtlety of colour depending on how hard you press.  It's one of the main features of working on a desktop that remains superior to the iPad version.

Here's an up-close look:

Up close, closer than I look while actually painting, you can see metallic green pain near the top swathed in more liquid greens. The little greyish tadpole strokes in the bottom half show how varying pressure even in a single stroke can add to the detail. 


A few of the beetles were shiny brown shades, others were multiple bright metallic shades. Another nice feature in ArtRage is you can store and name specific palettes.  Here's one of mine, for Trachys:

Custom colour palette for Trachys, the most brilliant of the subjects. You can see the point of grey chosen on the colour palette at right that I've listed as "grey dots". I found that often, the colours I chose needed to be more brilliant than the ones in the photo references to "read" similarly to the eye. 

I also saved a custom brush that I found was useful for fine detail, hairs and lines on a number of the beetles. Here's a sample of a few light-colour brushstrokes on a dark ground from the painting for Texania:

Custom brush menu. You can save multiple menus, and make them available to more than one file. I've placed some brush strokes on the white area beneath the menu so you can see what they look like without the rest of the bug's head.


If you'd like to learn how to save your own custom tools, I made a short video tutorial last year:



ArtRage is powerful for painting, but sometimes a little less perfect for editing. A couple of the beetles had a kind of "squashed banana" look to them as a result of me trying to inject more dynamic poses and bending them where they don't bend. When I went in to fix them, I used Photoshop Elements 6, the eraser, free transform and the clone tool.

Here's examples of the bent beetle Paragrilus (left), and unbent (right).

Paragrilus, in a dynamic, twisty, squashed-banana pose on the left, and fixed using Photoshop on the right.


There are selection tools in ArtRage Studio Pro, as well as some tools called templates that can be used and I suspect could have done the job in fixing Paragrilus's tilted back, above. I'll have to experiment some more. In this case, I went with tools I already knew to make the correction, and ArtRage allows you to save files in Photoshop's .psd format, even keeping layers intact.

Have any other scientific illustrators tried using ArtRage to do their work?  I'd be curious to see other examples or get feedback on this project. I would certainly use it again, perhaps even with digital pencils as I become more comfortable with them.
