These are two illustrations of the same subject using a different atmospheric color gamut for each. They are colored pencil on 2ply bristol paper.
In August of this year the Corpse flower, Amorphophallus titanum, bloomed at the Denver Botanic Gardens. This is a sequence of photos of the process I used in creating this drawing using graphite and carbon dust.
The initial contour drawing on Strathmore 500 series semi-smooth bristle
I began by brushing on carbon dust to establish some soft light to middle values. Then I started to draw in the details of the folds of the blossom with an F graphite pencil.
I continued adding carbon dust for the soft shading followed by graphite for the details of the folds.
The upper-most part of the blossom is mostly carbon dust.
The finished piece with labeling,
This is a time-lapse video of a quick study of a tomato. I used two pencils (a 2H and a B) and a kneaded eraser.
This is the contour drawing transferred onto Strathmore 500 series 2 ply bristle velum surface.
The next step was to establish all the tonal values with a relatively medium-hard grade graphite, in this case a Staedtler Mars # H.
This is the finished drawing after the darkest tones were refined using a softer/darker grade graphite, a #HB and #2B blended and smoothed with the #H
