WORTH REPEATING

This subject was addressed a long time ago, but it is so critically important that it bears repeating. Of course, it’s about values because, without a thorough understanding of them, you cannot create significant paintings.

Many teachers assume that we all know what “value” in paintings means, so they don’t really elaborate and tell us HOW to see them. The concept is easy to understand when we’re talking about a greyscale, but extrapolate that to color, especially the various colors juxtaposed together to make a painting, and the values concept becomes murky.

You can make an entire painting a monochromatic green or even pink and, as long as those pinks have correct values, your painting will “read” and make sense to the viewer no matter what color you make it. Value is simply how dark or how light that color is.

Yes, but so what? Where’s the “how?” Well, first you have to learn to squint enough at something until the color disappears and you are left with a percentage of light. What amount do you see? Make your own value scale and go around your house placing it next to various objects; squint to make the color disappear so that you can just see the value of the object and not the color. This is a great way to train your eye.

Here is a value scale you can print, showing values 1-9 with the addition of black (which is the absence of light) and white. The lowest value is 1, or 10 % light; the next is 2, or 20% light and so on, up to value 9 at 90%, with white being 100% light:

When making a painting, values aren’t actual light, of course, but values create the illusion of dark and light in varying degrees (shadows and highlights). Value deals with the lightness or darkness of a color.

Here is part of Bouguereau’s Vendangeuse (The Grape Picker) in color:

And here it is in greyscale, showing just the range of lights and darks (aka “values”):

Vendangeuse (The Grape Picker)BouguereauGrayscale

And here is the pink version:

So, even in pink values, we still see the little girl, instead of a Botox Babe.

When we do a value-scale underpainting, we are separating the problems of seeing values in one hue vs. seeing those values in juxtapositions of many colors (hues). This makes the painting much easier to execute, and more accurate, because now you have a process.

And that’s why I say you must know how to see value because value analysis and then value duplication is the basis of all perception. It is the common denominator for the replication of all things, whether landscapes, still lifes, or portraits.

PART 7, CLASSICAL ACADEMIC APPROACH, MIXING VERDACCIO

Before you begin your verdaccio underpainting, make sure you have completed everything you want to accomplish with India ink, charcoal, and gesso and/or gelatin in bas relief, so that your rendering looks as perfect as it can.  This functions as your value map for the underpainting, and if it is perfect, nearly everything at Value 5 and under can be quickly glazed, rather than painted.  Of course, the need for the perfect underpainting is that glazes are transparent, and everything will show through!

Look closely at the enlarged version of this drawing; can you see the areas where it seems to be especially white? Those are the places where, if you could run your fingers over the board, you feel the bas relief of the gesso that has been built up only in the areas you want to advance, to give the painting extra dimension.  Pretend you are a sculptor and pay special attention to areas like jewelry, headwear, the forehead, nose bone and tip, shoulders near the viewer, lower lip,  muscle structure, illuminated areas of dark garments, fabric folds that are closest to the viewer, and anything else you want to advance.  Make sure you smooth those built up edges so they blend smoothly into the board surface–you don’t want them looking pasted on.  You should not see the physical edges of the build up:

Mixing verdaccio in nine values is the next step. Here is where you will make your life so-o-o much easier if you have purchased Frank Covino’s Controlled Palette.

PaletteFront

Before mixing any paint on the Controlled Palette, coat it lightly with olive oil.

To mix verdaccio:

*Put 2, 8″ strips of chromium oxide green on Value 2
*Put 1, 8″ strip of mars black on Value 2
(= 3 strips total on Value 2)
Mix together thoroughly for a “Value 2 verdaccio.”
Value 1 is comprised of equal parts of Value 2 with Mars Black.
Values 3 – 9 are made by the addition of Flake White to Value 2, then 3, etc. (aka a “color string”).

Then cover it with Saran Wrap (the most non-porous wrap in my tests) and put it in the freezer until you’re ready to paint. Even better is to buy multiples of the three colors and some empty tubes, and tube your mixtures. That way, you won’t have to mix it again for a year or more.

P. S.  Just a note to let you know of an upcoming workshop

Hello, readers. The Arizona Renaissance Art Guild is hosting a one-week workshop with Maestro Frank Covino, art teacher extraordinaire. If you will be in the Phoenix area on April 6-10, 2015, we would like to invite you to attend and make some new painting friends.  The cost for the week is $695.  Respond to this post if you are interested.  We still have two spaces available.
