Reestablishing the Drawing

Over time, the shapes in a painting may diverge from those in the original drawing. Sometimes this is intentional, but often times, the proportions and viewpoints just get slightly off and the painting no longer reads correctly. At this point, it helps to reestablish the drawing.

This week, I put the paintbrushes down and picked up a stick of vine charcoal to correct my ellipses and adjust the various objects to be consistent with a single viewpoint. The nice thing about using vine charcoal is that you can easily erase it with a dry bristle brush.

By this point, I’ve lowered the viewpoint and reduced the size of the base of the front glass. I also extended the back glass bit further to the left so that it appears to be the same size as the front glass.

My attempt at rendering the scallops along the rim of the bowl doesn’t read correctly. The bowl looks like it is pinched and lopsided. Also, the reflections and shadows don’t really convey roundness.

Here I’ve raised the front rim of the bowl and really worked to correct all of the ellipses. Once I was satisfied with the overall shape, I rendered the bowl, as if it were flat-shaded. Now when I go back and add in the reflections, they will be subordinate to the shading and this should help to preserve the roundness of the bowl.

The glasses and the bowl work well together, but I still need to lower the viewpoint for the wine in the decanter.

On a Roll

I made a lot of progress this evening, painting glass and brass.

The brass bowl was actually pretty easy to paint. First I used some Permanent Alizarin to clarify clarify the shape of the bowl on the left side. Then I mixed up a greenish hue, consisting of Cadmium Yellow Light and French Ultramarine Blue, desaturated with a bit of Burnt Sienna. I painted the bowl from dark to light, and then went back with a brush loaded with a mix of Permanent Alizarin Crimson and Cadmium Red to color the reflections of the cloth and desaturate the green.

For the bottom of the decanter, I mixed up a fairly bright greenish white, using a mixture of Yellow Ochre and French Ultramarine Blue. I painted the glass at the bottom with the darkest mixture and then streaked in lighter values, in some cases, applying white straight out of the tube. I also used a thin, transparent green to desaturate the purple representing the top surface of the wine.

I used the same technique for the bases of the wine glasses. At this point I still need to adjust the roundness and then paint the glass at the top.

This is the painting at the end of the evening. Not bad for a few hours of painting. Now I can go over the entire painting, adjusting shapes, values and colors, while making decisions about hard and soft edges.

Here’s my punch list for the painting:

  1. Lighten the left side of the table.
  2. Darker, more painterly, scumbled background.
  3. Finish the top of the glasses.
  4. Wine glass shadows should start at stems.
  5. Adjust shape of glasses and bottles for consistent eye level.
  6. Extend decanter shadow onto cloth.
  7. Rework the colors and folds in the cloth for better contrast and more realism.
  8. Adjust color of right side of table to match left side.
  9. Paint glass effects in middle of decanter.
  10. Rework cork for more contrast and detail.
  11. Add details like stems and shadows under cloth, bottles, and glasses.
  12. Add highlights.

Value Scale

Gary showed me this simple method for judging values in my painting. He uses an eleven step value scale, much like Ansel Adams’ Zone System. Gary’s scale has six primary values, numbered 1 through 6, and five half-steps that lie in between. His insight, which seems obvious in retrospect, is that you can use standard palette colors, straight from the tube as examples of values on the scale. The picture below shows five of the standard palette colors with their positions on the value scale.

In a typical painting,

  • White will be reserved for specular highlights.
  • Prussion Blue will be reserved for the darkest darks.
  • The shadow values will start at Burnt Sienna.

This means the bulk of the mid tones will have values in the narrow range between Yellow Ochre and Burnt Sienna.  Mid tones are important – they make or break a painting – but they are hard to nail because they occupy such a narrow portion of the value scale.

Gary recommends figuring out the mid tones by process of elimination. Start with the knowns, like the blackest blacks in the shadows and the whites of the specular highlights. Then work your way up out of the darkest shadows towards the mid tones. Once your figured out the shadows and the highlights, all that is left is the mid tones, and by this point, you have a lot of paint on the canvas to help you make judgment calls.

Gary also stressed the importance of using the entire value scale in order to make the painting more interesting. It doesn’t matter whether the scene is light or dark – you use the entire range. If it is a night scene, streetlights and stars will be pure white, and the moonlit mid tones will be blues with values between Yellow Ochre and Burnt Sienna. If it is a sunny day in White Sands, New Mexico, the glint of the sun will be white, and the sunny sand will be made up of mid tone grays with values between Yellow Ochre and Burnt Sienna. In both cases, the shadows will start at Burnt Sienna and go all the way to Prussian Blue.

Making Progress Again

I just returned from a trip abroad, so this is my first post in a couple of weeks. Gary is at the Hermitage in St Petersburg, so Jim Phalen is our guest instructor for the week. Jim is a master of paint surface techniques and very knowledgeable about art theory and history. The photos below show my progress for the week.

In my first session back, I worked on the reds, painting the apples and the cloth.

I took Jim Phalen’s advice and extended the Burnt Sienna underpainting across the white tabletop. Then I notched out part of the cloth on the right side in the back to make the composition more interesting.

Painted the pear and the tip of its stem.

Painted the tabletop, the inside of the decanter, and the cork.

Marching Orders

Had my second weekly critique today. Gary used the time to demonstrate how to choose the right values for each part of the painting. He says the hardest values to nail are the mid-tones, but it is these values that make or break a painting. The reason mid-tones are hard is that the artist actually has a choice. The lightest lights and darkest darks are easy to place because there is no choice – the limited range of values available in paint forces the darkest shadows to black while reserving white for specular highlights.

I like to think of the process as putting together a jigsaw puzzle. With a puzzle, you start with the corners then move to the edges and then the center, always moving from the known towards the unknown, always triangulating from multiple directions. In a painting, you start with the obvious known values which are the darkest shadows and brightest highlights. Once these are placed, you can work up out of the shadows and down from the highlights until the mid-tones are boxed in. At this point, the choice of suitable values is smaller and more manageable.

Gary has painted a number of suggestions directly on my painting: (1) the horizontal gradient in the background should start at a much lighter value on the left and go to jet black on the right; (2) the right side of the table near the red cloth will need to go very dark; (3) the wine and the shadows on the fruit and the right side of the bowl need to go almost to black; (4) the front edge of the table needs to be pretty dark.

If you look at the image above, you can see some of Gary’s suggestions, painted directly on my canvas. I find it fascinating that the background should go from a fairly light, chalky gray on the left to jet black on the right. It is also amazing that the portion of the table top adjacent to the red cloth will be a fairly dark, olive drab. If Gary has these colors spot on – and I suspect he does – they will illustrate how hard it is to nail the mid-tones without the context of the adjacent lights and darks.

Here’s the gradient, roughed in to Gary’s specifications. It actually looks pretty good and nothing like what I would have imagined from looking at the first picture.

At this point, I have put in a more dramatic gradient behind the tableau.

Solid

Here’s my Word-of-the-Week image for “Solid”.

The crate is made from a wooden box and six very small window mats. The rivets are from the Michael’s jewelry crafting department – they are self-adhesive faux pearl halves. My original plan was to spray paint the box black and then use a drybrush to add rust and grime. I also wanted to add a cold, cloudy and gray, windswept sky.

The class discussion was great and I came away with a bunch of ideas to improve the concept. Gary says that since I took the time to make the box I will have to actually put it in one of my still life paintings.

This exercise meshed nicely with my theatrical set building experience and got me thinking about the possibilities in constructing sets and dioramas to use as source material for paintings.

Wine and Apples – More Darks

Today I mixed up some deep burgundies for the decanter and the wine glasses. I started with Permanent Alizarin Crimson, then mixed in some French Ultramarine to move more towards violet, then darkened the mixture with Burnt Umber.

I’ve been working to establish my darkest darks so that I will have some reference for my shadows and mid-tones. Soon I will need to nail down the other end of the scale by finding the light mid-tone value for the tabletop. You see, I need to reserve white for the specular highlights – when the painting is done, nothing will be white, except for the small reflections on the glass and the fruit. This means that the table top will need to take on a value more like the cloth but then the cloth will have to go darker, which will push the shadow on the cloth almost to black. When I lose white, the entire value range will compress.

Wine and Apples Background

This evening I mixed up a string of dark, slightly warm neutrals for the background. I started with a mixture of Burnt Umber and Prussian Blue, which I lightened with Titanium White. As I got to the lightest darks on the left side, I found I needed to add a bit of Yellow Ochre and Burnt Sienna to keep the mixture warm enough. I like the dramatic chiaroscuro look of the painting, but think the darkest portion of the background on the right side needs to go darker.

This was my first time painting with Neo Megilp. This strange sounding medium is added to the paint to make it settle and flow. Notice how the dark paint with Neo Megilp is velvety smooth, while the Burnt Sienna in the underpainting shows lots of brushwork.

Tomorrow, I hope start on the darks of the wine in the decanter and the glasses, probably with a mixture of Permanent Alizarin Crimson and Burnt Umber.
