“Using Light to Create Realism in Botanicals”, taught by Robert McNeill at The Huntington Library, Art Collections and Botanical Gardens, October 3-5, 2018 was an amazing 3-day workshop!
Robert began with a thought-provoking quote by Leonardo da Vinci: “A painter should begin every painting with a wash of black, because all things in nature are dark except where it is exposed to light.” We were all inspired by the meticulous approach and techniques, and how he used light to reveal the drama, depth, form, transparency and detail of the subject.
Snapshot’s from Robert McNeil’s workshop.
He discussed the importance of capturing the effect of light, how it requires controlled tone/value to describe the relative lightness or darkness of color, creating an illusion of form. When we perceive tones/values, they are always relative to each other and never seen in isolation. Therefore, simultaneous contrast is always at work. Being able to create and control tonal/value gradation in watercolor is an important skill to acquire, along with the ability to see them and record them accurately. This controlled effective tone/value can take your work to a higher level by creating “enhanced relations through convincing volume”. Robert’s painting of the Cardiocrinum gigantum was a perfect example of how a painting encourages the viewer to look closer by revealing detail that has been made more apparent by light.
During the workshop, Robert shared examples of his work to illustrate the process and techniques of using light to create realism. He stressed the importance of constantly analyzing the process as one worked. Generous with information, patient in answering every question, his enthusiasm, interest and support were always encouraging.
Lighting: Robert reviewed ways to light your subject, explaining that correct intensity and direction of light for the subject is important to reveal aspects crucial to capturing its essence. He usually uses overhead lighting that is controlled. He noted that it is not always helpful to place subjects in strong light, as extreme contrasts can create more problems than it solves. His painting of Abies koreana ‘Carron’ beautifully illustrates how studying the play of light across all aspects of his subject creates a sense of drama. We were encouraged to think about lighting in the subject’s natural habitat, and what would be typical of natural lighting. It was suggested that we avoid overhead lights in a room, and also light from windows, keeping light consistent on the subject you are painting.
Documenting Stage: Thorough and objective observation of the subject is key. Observe the subject from all angles to ascertain which angle would convey the most convincing nature of the subject. Carefully look for overlapping and foreshortening. (Taking photos as a reference is OK, but best not to rely on photos.) For details use eyes, and measure subject for 1:1 scale, carefully documenting information, as subject will change by growing, wilting or drying out. Observe the difference that the angle of light source makes upon subject for revealing visual strengths. Fifteen minutes were given to make three quick loose, linear drawings of our subject, the rose. Fifteen more minutes were given to make three more quick, linear/tonal drawings. Color matching was made at this part of the documenting process. He asked us to be mindful of the way colors are affected by the color next to it. Robert uses Winsor Newton transparent paints only, and always mixes his own greens and oranges.
Development Stage: We began this part of the process by producing a full size 1:1 scale drawing, referring to documenting stage material to ensure accuracy. Robert shared examples of his work showing meticulous detail to be used as a reference for final painting. Next we were to make an accurate tracing from the drawing of our rose. The tracing was placed in a variety of positions before making a final decision and transferring it to watercolor paper. After transfer, it was advised to always re-work to produce more accurate drawing. He cautioned us about erasures on watercolor paper that can cause paper’s surface to breakdown. Robert also gave a tip about using a piece of silk and an agate to smooth a ruffled paper surface.
Demonstrations:
Lifting Preparation.
Winsor Newton Lifting Preparation may be used for ease in lifting paint for veins, etc.
Use 3 layers of lifting prep, allowing 2 hours of drying time in between each layer.
You may use lifting prep over layer of wash.
Best to only use in small areas, and be extremely careful not to go over pencil lines.
Ox Gall Liquid.
Mix 3 drops of Winsor Newton Ox Gall in ¼ cup water. Keep small marked water jar with this mixture separate from other water.
This mixture helps paint to flow easily.
You may use Ox Gall and water wash on paper first, and when slightly damp, add paint wash. Or, you may use Ox Gall and water and paint all at the same time.
Never use paint with Ox Gall for dry brush work. Keep paints and brushes used for dry brush separate.
Dry Brush Technique.
Using a Spotter, WN 000, Robert demonstrated stipples and tiny fine lines.
Robert used a separate plate with tiny dots of dry paint, moistening his brush with a damp sponge.
For texture, only hit the high points of the paper.
Can use damp brush on top of stipples very carefully.
It is important to avoid using one technique, rather use a combination of wash and dry brush. Continually analyze the process you are using.
Indian Yellow may also be used as a light glaze over finished painting…very carefully.
During the three days, we all talked about Robert’s useful ideas and techniques that made an impression on us. At the end of the class, works in progress were placed on a table for sharing. Robert emphasized the importance of seeing all work within the group as a valuable learning experience. Following are ideas and techniques that resonated with members of the class:
“I very much enjoyed learning how to make fast, free sketches while not looking for details, but instead seeing the overall shape.” “Learning how to focus on the contrasts, especially the dark and light.” “Watching Robert using a scalpel to release bits of dried paint from the paper surface.” “Experimenting with Ox Gall as a wetting agent in the water jar, and learning how to use WN lifting preparation was very interesting and highly useful information.” “Hearing the words: ’Slow down, think, organize and plan’ was a reminder to always approach work with pre-planned thought.” “Importance of continually analyzing the process.” “Reactivate the line after a trace to create depth as a reminder while painting.” “Remembering to soften outside edges while keeping them sharp, yet light.” “Using a damp sponge for moisture control when using dry brush techniques.”
The time flew by far too quickly! We are all grateful to Robert McNeill, both as a brilliant artist and as an excellent teacher. His meticulous attention to detail and thorough observation of his subjects are reflected in the light and form he achieves in his paintings. He inspired us to see the subtleties and nuances of light as we create art. Thank you also to the Education Committee for bringing him here, to Tania Norris for supplying the subjects, and treats, to The Huntington for hosting us, and to BAGSC.
