Workshop Description

This will be a hybrid workshop: the same class will hold students of both graphite and pen nib and ink techniques. All the hints and explanations about both media take place in the same room, but individually each attendee will use one technique for their project. Participants will have the instructor’s full assistance and guidance, since the workshop is limited to the same number of students as if it were a single technique workshop.

Graphite content:

Participants who choose graphite will learn:

  • Methods for accurate observation of light and shadow with all their subtle nuances
  • Methods of sharpening, handling and moving the pencil for an improved application and filling with graphite
  • Use of delicacy in drawing for efficient use of time, good finishing and preservation of the integrity of the paper
  • Methods for total filling with layers of shade in a gradual mode from light to dark tones
  • Practical rendering of textures and different colors of objects represented as shades of gray; recognizing luminosities, reflections and contrasts; practical and fast forms for the rendering of hairs and thorns.
  • Prevention of errors, paper deformities and irreparable damages

Graphite prerequisites:

Pen nib and ink content: refined hatching techniques

Participants who choose pen nib and ink will learn:

  • Understanding how the pen nib works and the physical aspects involved in its performance, thus learning to select the best material at the moment of purchase.
  • Methods for preserving the pen, avoiding corrosion and damage and even improving its function by sanding and keeping it always clean as new.
  • Practical hints to facilitate general aspects of the work, related to the traits of the ink and its tendency to dry and change, as well as to the economy of movement and prevention of troubles.
  • Methods for the practice of hatching, challenges involved in it and how to overcome them.
  • Shading with hatching and how to render good 3-D drawing illusions of any kind, taking advantage of characteristics of our visual perception and our cognitive and physiological traits.
  • How to represent by hatching the variety of shapes and forms of the natural elements and the technical choices available to render a pen nib shading, having previously some graphite shading as basis.
  • Corrections and prevention of dramatic errors.

About the Instructor

Rogério Lupo, born in 1970 in São Paulo, Brazil, is natural science illustrator and teacher of biological illustration since 1998. Bachelor in Biological Sciences at University of São Paulo (USP) in 1997, had Art Classes at Escola Clássica de Arte (Classical School of Art), São Paulo, from 1993 to 1998. His illustrations are present mainly in academic works, especially on taxonomy and ecology. His quest for more care and artistic value, even in academic and technical illustrations, enlarged his professional potential leading his original artworks to be purchased to integrate private or institutional collections.

Rogério works in a variety of media, as he is not able to choose one favorite. He always aims to share his experience in didactical material, making it available for free on internet. Some of his works have been awarded in important competitions, for instance the first prize in 2002 and 2003 of the Margaret Mee National Contest (Brazil) – black and white category – and the first prize in 2010 and 2013 of the Margaret Flockton Award for Excellence in Botanical Illustration (Australia).
