Value Sketches at Cooper Lake

There can be a freedom in setting limits for yourself. A narrowing of focus within specific constraints can lead to a deeper exploration of what’s possible with what you have!

Recently I’ve been sketching with very simple tools, just ink pens and a water brush. I’ve been using a Platinum Desk Pen and Pentel Brush Pen.

Before the start of school, our family took a last camping adventure to the beautiful alpine Cooper Lake. Tucked in the Cascade Mountains, it’s a lovely spot for boating, swimming, and relaxing with friends.

Canoeing out to the middle of the lake, the snow-capped mountains of the North Cascade Mountains emerged. I quickly sketched as we drifted slowly, working to capture the slope of evergreen trees.

I loved sketching and used a minimal setup with just my A6 softcover Midori MD Notebook, Platinum Desk Pen, Pental Brush Pens (grey and black), and a water brush.

While the brush pens contain waterproof ink, the ink can be diluted and washed with water if applied quickly. I used a water brush to swiftly add tone for simple value sketches. Sometimes, my initial penstroke leaves a mark, but it doesn’t bother me: it’s just part of the process! These simple toned sketches force me to edit, simplify, and focus on values: areas of light and dark.

The grey Pentel Brush Pen is especially fun—and new to me! You can create a range of greys with a beautiful tone, and it can be layered upon itself to create deeper blacks. For even richer darks, I add marks with the black Pentel Brush Pen.

We always pick up snacks before starting any adventure!

My goals for this trip were to relax with friends, play on the water, and explore art as I had time. This simple sketching setup was easy and fun, and I loved creating a little series to preserve the memories—plus, treats are a must for every trip!

Value Sketch Tips

  • Squint your eyes to see the values in a subject on location.

  • Focus on big shapes and leave out the small details.

  • Simplifying a scene by categorizing it into 1,2,3 levels of value.

  • Turn a reference image into black and white to practice!

Additional Supplies Recommendations

Watercolors
For a mixed-media approach, consider incorporating neutral watercolor hues such as Payne’s Grey, Graphite Grey, or Neutral Tint into your sketches.

Waterproof Ink
De Atramentis Document Ink, a waterproof favorite, is available in Black, Urban Grey, and Brown. Pick a pen and its corresponding ink converter and fill it with your chosen ink color.


Happy painting!
