Value Sketches

Value Sketches
The following value sketches illustrate the visual thinking process described in the previous blog on value patterns.  The process is one of discovery and experimentation. Keep a sketch book and experiment with various compositions in conjunction with value patterns.  If the value pattern is troublesome, change the composition.

Value Painting
It is almost spring time and I begin teaching watercolor for the design and art students at the University of Washington once again. I always look forward to this quarter because the watercolor course is fun and challenging and it gets me revved up again to paint. I have been busy working on a new book for Routledge Press out of the UK and the manuscript is due in June. OUch! But it is a fun challenge. the book is entitled: "Urban Design: The Composition of Complexity". which brings me to our lesson of this week: value painting and its relationship to composition.

Value painting as i have discussed involves designing a value pattern within your composition that dramatizes the light and dark relationship between and among shapes. The value pattern helps structure or assemble the composition into a coherent whole. Then and only then do you want to begin adding color.

My Process of Value Sketching
Either from field sketches or photographs or both, I begin doing small 3x5 inch Pentel Sign Pen sketches in my sketch book. I try a number of compositional configurations, sometimes zooming in on a subject for more drama and sometimes highlighting a certain feature of the subject. I then begin playing with various value patterns around a selected center of interest to see how the mood of the value pattern is emerging. For example, if i am using middle and dark values at the center, the mood may be subdued or diffused in the lighting, much like my sky today looking out of the studio on Whidbey Island--rainy and cool. i might want to go with more contrast in the light and use a light value with a dark value, essentially using strong dark shadowing around the center of interest.

One important aspect of this sketching process or process of visual thinking: it is a process of discovery. Meaning that by exploring and sketching various combinations of value patterns i discover other directions and approaches. There are times when i begin painting with a value pattern and have a really tough time making the painting work. I then go back and change the composition to provide a different and more dramatic value pattern. It is really a cyclical process of discover like design. Do not try to intellectualize the painting in your mind before you begin. Dance with it as it evolves through your hands and eyes and mind. I will add some sketch examples soon if i can figure how to import them. More later, gang. Keep painting and think VAUES.

Value Painting

Value Painting in Watercolor.

Hi painters! I just talked to a good friend in England as he settles into his new painting studio in their wonderful garden. Time to paint again. I have been sidelined working on a new book entitled: "Urban Design: The Composition of Complexity" about the elements and principles of design composition applied to complex urban settings. Having fun.

Value Painting. Why is it so important?
The next couple of sessions will involve what I think is the most important aspect of painting: value relationships. Why? As you arrange shapes into a larger pattern or composition, you begin telling a story in the composition. The color adds mood through temperature (warm or cool dominance) and local colors (an apple is red, green and yellow). but, the drama of a painting and how the composition is structured or assembled is done through value patterns, the relationship of light to dark. essentially, the eye of the observer will go to the point or area of highest contrast of light--lightest next to darkest. To soften a mood, i may have values in the mid range next to each other that reduce that contrast, reducing the effects of the light--middle value next to a mid-light value.

Value Scale.
In printing, a nine value scale is often used. In painting, a five value scale is more common and is actually a derivation of a three value scale--something like this: (1) lightest, (2) middle value, (3) darkest value. Let's expand that to the following: (1) light, (1.5) mid-light, (2) middle value, (2.5) mid-dark, and (3) dark. So we will use a five value scale for our exercises and experiments.

Recommended Preparation.
What i have learned through practice, reading, self-teaching is that the value pattern of your painting and the composition are inherently entwined. In my sketchbook, i rough out a number of compositions, around 3x5 inch sketches until i start to get a compositional relationship that i like--that has some strength at the center of interest with movement, direction, etc. Next, i do quick value studies of each composition using the value combinations below, emphasizing the center of interest as the place i want the observer's attention. Here are the combinations:

(1) light next to (2) middle value for a sunny and hazy affect;
(1) light next to (3) dark value for a bright and strong sun with strong shadow affects
(2) middle next to (3) dark value for a moody, overcast or darker affect.

Skip Lawrence in "Painting Light and Shadow" helped me greatly through his writings and examples with a nice concept: the majority of value change (assuming three values 1, 2, 3) occur in and around the center of interest with the remaining value occuring predominantly everywhere else. Watch out! Your head will hurt as I did not say that everywhere else is the same color, simply the same value.

For example, for a moody day, i choose to put the mid and dark values at and around the center of interest and everything else is a light. where the light value is can be many colors, local colors, but they are all roughly the same value. Yahoo! Mood. With Skip Lawrence's approach, you can arrive at a matrix of nine moods for the SAME COMPOSITION WITH THREE DIFFERENT CENTERS OF INTEREST.

Exercise.
sketch nine small studies in pencil approx. 2x4 or 3x5 largest three per row, three rows
in row one, select a center of interest and with one color paint three value patterns using that center of interest: 1/3, 1/2, 2/3.
for row two, select another center of interest in the same ccomposition and do 1/3, 1/2, 2/3
repeat of a new center of interest for row three.

ask your eye to tell you which sketches have more drama, which less? and do i need to alter the composition to improve the value patterns?

Try these and get back to me as I am back in the saddle again.

Greens Revisited

Greens Revisited
Hi gang, have been busy with new artist in residence studio on my property and a new book project. A reader had some concerns about the green exercise I last gave so will clarify.

The basic idea is to practice making greens in each family of colors (transparent delicate, intense, and opaque) with the basic blues and yellows. you will be able to make lots of greens just by varying the amount of yellow or blue that you mix.
then, add the red in that family to the green mixtures of yellow and blue and you will create a green gray, very useful green colors. you will see the mixtures going from orange-brown (too much red and yellow) to blue gray (too much blue). practice.
then, you can do the basic mixtures and try some of the staining or intense colors, the pthalos, to the basic mixtures and see how you can enrich each of the green mixtures.

essentially that is the intent of the exercise. practice and i will have another section for you at end of next week.

keep painting, ron kasprisin

Common Flaws

Hi gang, sorry i have been away, went fishing in Ontario Canada and had a great time.
This section is on common flaws when beginning your watercolors. Flaws is a weak term but my students view them as that so we will use the term. When beginning watercolor painting, there are characteristics that show up in your washes etc. that are normal and natural and will go away with time. Here are a few:

BANDING. when doing washes for practice and you are using a back and forth brush stroke, moving down the page as you paint, you may get banding marks in the wash. this is usually due to a number of things:
1. you are putting too much pressure on the brush, driving the brush into the paper where the brush has more than one point of contact with the paper, leaving two marks or streaks not one
2. your brush angle may be too low, again putting more than one part of brush on paper and leaving a banding affect.
3. i suggest really lightening up on your pressure, move your hand away from the ferrule up the handle, and put the pressure of your hand into your pinky with the pinky resting on the paper and moving with the stroke, it really helps.

BLOSSOMS AT BOTTOM OF WASH. when you get to the end of a wash, and the paper is dry, the bead left at the bottom will usually not keep running down the paper but will sit there. here is where the example of drying wash sucking up the wetter wash comes into play. as the wash above starts to dry out, it pulls the wetter bead back up into itself (the damp dry sponge affect on your wetter brush) and you will get a blossom. HINT: wipe your brush and use it as a blotter and run it over the bead to pick up the excess water into your brush from the paper.

FLOODING. i prefer students to be more wet than dry so i dont worry about flooding where you have water from previous strokes running down the paper into the new wash area. sometimes this can be the cheaper studennt grade paper or just too much water in the brush. just keep practicing and dont get too dry.

BREAKING EDGES. get in the habit of breaking or lifting out your edges as you finish a wash. quickly either add water no pigment to the end of the wash as if doing a merging and let the wash edge just soften out like cotton; or quickly go into the wet edge with a damp brush and lift our or break the wet edge to soften it and avoid hard edges.

More later, have fun. Ron K

watercolor lesson: greens

Watercolor Lesson: Greens

Greens are dominant in most landscapes and often provide real challenges for beginning painters. Architects and landscape architects are traditionally fond of olive green and are often surprised to find out that it is actually a green gray: all three primaries are present and the red quiets down the color intensity of the yellow and blue mixture.

Mixing greens requires some practice with each palette family and with the staining colors.

Basic Greens. for each palette, the delicate transparent, staining and opaque palettes, mix the yellow and blue in varying amounts for a range of greens from yellow green to green to green blue. For example, mix azo yellow and cobalt blue to get a nice bright green. vary the amounts of azo and cobalt to mix a range of greens. Repeat this for each of the other two palettes, pthalo yellow and pthalo blue, and yellow ochre and cerulean blue.

Green Grays. Now mix the family red with each of the green mixtures and do a number of variations (you will see the green going from a green to a brown so be careful and use your eye judge). for example, mix azo yellow, cobalt blue and add rose madder to take the brightness away. Next for the same palette family, instead of using the family red, as in red madder, mix a staining red such as pthalo red or alizarin crimson to see the more intense version of the green gray. do for each family.

Mark down under each mixture what the colors used are so you have for reference.

More later, have fun painting.
