A course by Julia Rouaux
Julia Rouaux has always been passionate about nature, even as a child, and she never missed an opportunity to draw it. This led her to take a scientific illustration course after completing her degree in biology and, ultimately, to combine both of her passions while pursuing a PhD in natural sciences.
She currently works as a freelance illustrator and teaches scientific and naturalist illustration. She has created illustrations for scientific studies, informative publications, undergraduate and postgraduate theses, and educational materials including images for three illustrated guides on mammals from South America and around the world.

FAQs
Scratchboard is a technique where you scrape away a layer of black ink on a white surface to create detailed illustrations, perfect for capturing textures, light, and shadow in naturalistic and scientific art.
This is an intermediate-level course; basic drawing skills and familiarity with art materials are recommended, but you don’t need to be an expert in scratchboard.
You’ll need scratchboard or Claybord, scraping tools like a craft knife or fiberglass scraper, pencils, microfiber cloths, India ink, carbon or tracing paper, brushes, plus visual references and basic personal protective gear.
You’ll learn how to research species, transfer sketches, create realistic textures and fur, apply light and shadow, fix mistakes, preserve and digitize your work, and understand the difference between naturalistic and scientific illustration.
You transfer your sketch using carbon or tracing paper, carefully pressing to mark key lines without distortion, ensuring your sketch stays true on the final surface.
Yes, you can digitize your artwork by scanning or taking high-quality photos, then refine details digitally for presentations or professional portfolios.
Naturalistic illustration focuses on artistic expression and the beauty of nature, while scientific illustration emphasizes accuracy and clear communication of biological data.


Excelente.
Excelente curso muy completo y bien explicado.
Eine Technik, die ich so noch nicht kannte -
sehr gut erklärt
mit tollen Beispielen.
Ganz herzlichen Dank dafür ...
It was so interesting to see how nature inspires people to create! It was a lovely course, although the materials were a bit hard to get in my area. But it was still a fun experience!
I love this technique and until taking this course had only been practicing with scratch paper, this helped me understand the differences between types of scratch boards and what else I can do with them . Excited to improve my skills!
