How to identify highlighting and shading techniques in period and how to use them in your own work. By: Thomas Paumer Augusta_and_tom@yahoo.com CVO, CBM, GoA Definitions http://www.watercolorpainting.com/glossary.htm Blending: Fusing two color planes together so no discernable sharp divisions are apparent. Blotting: using an absorbent material such as tissues or paper towels, or a squeezed out brush, to pick up and lighten a wet or damp wash. Can be used to lighten large areas or pick out fine details. Body Color: The mixing of opaque white gouache with transparent watercolor; or gouache colors in general. Chroma: The purity or degree of saturation of a color; relative absence of white or gray in a color. Cross-hatching: Using fine overlapping planes of parallel lines of color or pencil to achieve texture or shading. Used in traditional egg tempera technique; drawing in pencil, chalk, pen and ink; and engraving, etching, and other printmaking techniques. Gesso: Ground plaster, chalk or marble mixed with glue or acrylic medium, generally white. It provides an absorbent ground for oil, acrylic, and tempera painting Gouache: 1) Watercolor painting technique using white and opaque colors. 2) A water-based paint, much like transparent watercolor but made in opaque form. Traditionally used in illustration. Graded Wash: A wash that smoothly changes in value from dark to light. Most noted in landscape painting for open sky work, but an essential skill for watercolor painting in general. Gum Arabic: Gum arabic is produced from the sap of the African acacia tree and is available in crystalline form or an already prepared solution. It binds watercolor pigments when used with water and glycerine or honey. Masking fluid: A latex gum product that is used to cover a surface you wish to protect from receiving paint. Miskit by Grumbacher and Art masking fluid by Winsor & Newton are two such products. Also referred to as liquid frisket. Opaque: A paint that is not transparent by nature or intentionally. A dense paint that obscures or totally hides the underpainting in any given artwork. Trompe l'oeil: A term meaning "Fool the eye" in French. It involves rendering a subject with such detail and attention to lighting and perspective that the finished piece appears real and three-dimensional. Underpainting: The first, thin transparent laying in of color in a painting. Variegated Wash: A wet wash created by blending a variety of discrete colors so that each color retains it's character while also blending uniquely with the other colors in the wash. Wash: A transparent layer of diluted color that is brushed on. Watercolor: Painting in pigments suspended in water and a binder such as gum arabic. Traditionally used in a light to dark manner, using the white of the paper to determine values. http://artapprenticeonline.com/blog/art-terms-and-painting-tipslayering-and-glazing/ Glazing: A ‘glaze’ however refers to the application of a transparent color applied over a dried area to adjust the hue, intensity, or value and color temperature. In watercolor painting, artists layer thin transparent glazes and washes until they achieve the depth or saturation of color they desire. Acrylic and oil painters will also use or layer transparent ‘glazes’. It is very important to understand that layering is simply placing one layer of color over another, while ‘glazing’ is ALWAYS a transparent application. Layering : Layering is also a gradual buildup of light and /or dark values and requires several applications before the desired result is achieved. Usually the first application of color will cover the largest area; each subsequent application of color should be smaller staying within the perimeter of the first color. Think of a pyramid, each application is smaller than the previous. Right: Royal 17 D III f. 7v Edward VI receiving the book Author: William Forrest Title: The pleasaunt poesye of princelie practise, imperfect Origin: England, S (Bledlow or Oxford) Date: 1548 This is a very typical example of cross hatching. It is common, and most recognized, as the shading method in woodcuts, etchings, and ink drawings. The same method that is used to give depth to the medieval art piece in black and white, can be used in color to give similar affects. (see below) Left: Bibliothèque nationale de France, Département des Manuscrits, Français 598, fol. 13r. This is a non-typical, color example of crosshatching in a medieval manuscript. If you look the brush strokes in the floor create a pattern of density and shade without actually adding density or shade. You can also see how effective hatch work shading can be by looking at the woman’s waist line and draping fabric. The entire effect was created in hatch work.

How to identify and replicate hatching/ cross hatching Warning: the act of doing hatch work is extremely intuitive and subjective… I can only show the basics of how it is done. Each person will pick up on it at different levels and speeds. Please bare with me as I try to explain it the best I can… Luckily for us, hatching is the easiest shading technique to identify from a period source. Essentially, it is lines at varying spaces to create shape and form. That being said, it is easiest to identify with wood cuts (see below) and etchings. Looking at the image above, it is modern cross hatching techniques. Some of these can be replicated, but it is more important to show the types of shading and manipulation that can be done with lines. Hatching work can be done with an ink pen, quill, or paint brush. The color you use does not have to be black. (In fact some times it looks best not using black… I’ve gotten great results from brown.) This is probably the least used medieval shading technique. How to identify and replicate wash work painting Wash work painting is probably the most used form of medieval highlighting and shading. It is possible to use with glaire or other non-rehydrateable paints, but extremely difficult (as you cannot blend the lines.) The way to properly identify wash work is to look at the changes in the hue of the paint. While wash work directly changes the saturation of the color, it will not effect the hue. Finding these subtitle differences is important to determining the technique used, but it will become easier the more practice that you have with painting in this style. Please note, the “Lancelot du Lac” painting posted before and the “Christ Disputing with the Merchants” (right) are the same style of painting technique. Da Verona’s painting took meticulous effort to blend lines to create a smooth transition between the shades, while “Lancelot du Lac” is far more abrupt. Both styles are made by this method. Wash work painting works by changing the saturation/ intensity of your colors in a structured manner to create the effect of highlighting and shading. Now, that sounds rather wordy and academic… Everyone notices that the more water that you add to your paints, the thinner and less opaque your paints become. What this process seeks to do is use varying levels of more and more opaque paint in order to create the look of shading. Title Cutting from an Antiphoner Origin: Italy, N. (Lombardy) Date: c. 1430 - c. 1435 Artists: Stefano da Verona (active in Lombardy c. 1375 - c. 1438) To the left are pictures that I took from Master RanthulfR AsparlundR, KSA ‘s website. It shows a two step process in order to create the Trompe l'oeil effect. If you look at the top picture very closely, you can see at least 4 layers of different saturations of paint. The steps to create this effect are: 1. Prepare your supplies. You will need: Paint, extra paint wells, brush, and a paper towel or 3. 2. Determine the point in which the light will hit the object and how you want you shading to look. 3. Mix and hydrate your paint in one paint well (we will call this paint well A) and place a small amount of water in another paint well (we will call this paint well B.) 4. Move a small amount of paint from paint well A into paint well B. This will make paint well B a very light wash. 5. Use the wash in paint well B to lightly paint the object. 6. Wait for the paint to dry. If you find that your wash is too powerful or saturated, slowly use your paper towel to blot away and remove excess paint. 7. Once your underwash is completely dry, add more paint from paint well A into paint well B, making it a more saturated wash. Use this more saturated wash to paint the next ring of paint in your object. 8. Repeat steps 4-7 until you have a series of saturated washes to give the full effect that you desire. 9. At this point, you blend the lines between your shades of paint. To do this, lightly dampen your brush and lightly run them over the lines. This will create a nice, smooth transition in your paint.

Origin Italy, Central (Florence) Date c. 1340 The illumination to the right uses a strong mix of layered and washed painting. You can tell the layered painting because the artist uses another color of paint to highlight or shade, and then blends it into the painting. This changes the hue of the paint from the base paint. You can tell the difference between wash work painting and layered work painting because layered work painting uses multiple colors and change the hue of the paint. If you look at the Dragon in the illumination on the right, you can clearly see the shading (and form) created by adding green to the yellow dragon. Looking at the mountain on the bottom left of the illumination on the right, you can see clear swatches of white added to the paint. You can also se plenty of white highlighting in the border. There are things to consider when doing layered painting techniques: 1. It only works for paints that rehydrate. If you are painting with glaire or tempera, you will be unable to blend the colors. 2. If working with period or natural pigments, always research your pigments for interactions. 3. Remember your color wheel. If you are painting with blue and want to highlight something with yellow, it will turn green. Since layered work changes the hue of the paints, the most common use I have found is using a white to highlight a color or using a separate pigment to shade. I have also seen some layering work well with shading with blacks and browns. The process taken to create layered paintings is fairly simple. 1. Paint the base layer (this is similar to an underpainting but is usually more opaque.) 2. Let the paint dry . 3. Charge your brush with just enough water that you would use for blending, and slowly wet down the areas of your base coat that you want layered. 4. Charge your brush with the highlighting color and paint it to the watered area of your basecoat. This should allow your highlight color to mix with your base color on the paper. 5. If you find that it is not rehydrating and creating these highlights and shades that you desire (or it is creating more of a feeling of white work.) Allow the highlighting paint to dry a little bit and then charge your brush with a little bit of water and blend the highlight into the painting. Allowing it to dry a little bit before blending will allow you to have an even blend. If you do not have the time to allow it to dry before blending, make sure that you can get the even coat that you desire. Bonus: The highlighting effect with white work (pictured right) was created in a 3 step system. Step one was the basecoat in vermillion. Step 2 was to highlight and blend with white (probably lead white.) Step 3, is once the paint and the highlight was completely dry, they painted the white work over. This is a common theme when painting with layered painting. Above: Yates Thompson 12, 40v Author William of Tyre Title Histoire d'Outremer, continued to 1232 Origin France, N. (Picardy?)
