Pacific Sunset Step Two

Pacific Sunset Step Two
The painting turned out nicely. The two-step process involves laying out the shapes, basic contrasting colors and values in the first step and saving that work as an image. Then, in the second step, painting on top of that imported image goes smoothly and quickly. Refer the the post of step one to see where I left-off in step one.

You may download the SVG source in xml format of step two of this painting from Google Docs.

I have also used this two-step process successfully to paint falling water in in a mountain stream.

Pacific Sunset Inkscape Painting

This work in progress represents the first step in a new, two-step process with which I am experimenting using Inkscape 0.47. I have painted the basic areas in this first step. I will paint on top of this base image in the second step.

Inkscape can be quite memory intensive, so once I have nine or ten layers, each composed of gradients and filters, adding strokes or applying effects can take time waiting for the processor on my old PC to finish swapping. Moving parts of one layer to another layer, across too many layers, can be even more memory intensive. So this experiment will involve taking the painting to a point that satisfies me and upon which I can build. I will then export the work as a PNG, just as I have in for this post. This first step took less than one hour to paint. I mostly painted with a thin brush and then clipped the resulting shape from a rectangle so that the color below would show through the shape that I left unshaded in the top layer. Occasionally, I colored the shape and added it alone as a new top layer.

You can see the layers and palette that I used in the first step. The base image is build up in layers which are shown below.
layers step one
The background is on the top at the left while the foreground in in the bottom right. The image is made by stacking and aligning the layers row-by-row, from top to bottom and left to right. The palette also shows the order.

In the second step, I will import that PNG, add layers on top of the flattened image, and finish off fine points with brush strokes and filter effects.

The photo upon which this painting is based was released in the public domain. See the brilliant original entitled Pacific sunset by Andrew Schmidt.

Jenny Lake

Study of Mountain Reflection in Water


Jenny Lake is in the Teton National Park, WY. I chose this scene to study reflections in water because the original photograph contained high contrasts in the values across the water and because it is one of my favorite places. Reflections in dark water are a particular sort of challenge in Inkscape, so I have additional hints about painting high-contrast reflections to add to those that I outlined in the post entitled Painting water using Inkscape 0.47.

Two values of blue, two values of brown, two values of gray, and black were used as very thin brush strokes to compose the water. The browns and grays are all vertical strokes with vertical motion blurs while the blues and black are all horizontal strokes with horizontal motion blurs. The horizontal strokes also have the torn-edge effect while the vertical strokes have the ripple effect. I placed the dark strokes on the bottom and worked toward the light. The edges of each major color of the horizontal strokes would overlap if they were not interwoven -- that is, only the blurred edges overlap where the colors blend because of the transparency of the blurs. The real key is to break the vertical strokes with the horizontal strokes so the eye sees the reflection but it appears to be reflected on top of the rippling surface of the water.

In this study, I have not worked on the mountains (yet); they are tracings from the photo. I hope to work on the mountains at a later date, but for the time being, I have purposefully placed them "out of focus" as they are of less interest to me than the water in this study.
