Top 7 'Shadow-Trapping' Cyanotype Techniques to Explore for Beginners with Just Sunlight and Water - Goh Ling Yong
There’s a unique kind of magic in cyanotype printing. It’s a process that feels both scientific and deeply artistic, a dance between chemistry, sunlight, and imagination. At its heart, it’s about capturing shadows—trapping the ghost of an object on paper, immortalized in a stunning spectrum of Prussian blue. It’s an art form that strips away complexity, inviting you to create with the most fundamental elements: light and water.
Many aspiring artists feel intimidated by alternative photography, picturing complex darkrooms and costly chemicals. But the beauty of the cyanotype process, especially for beginners, is its incredible accessibility. If you have pre-treated cyanotype paper (or a simple two-part solution kit), some everyday objects, access to the sun, and a source of water, you have everything you need to start creating breathtaking prints. This isn't about perfection; it's about play, discovery, and learning to see the world in silhouettes and shades of blue.
In this guide, we'll walk you through seven simple yet profound "shadow-trapping" techniques. These methods are perfect for anyone new to the world of sun printing and are designed to unlock your creativity using items you likely already have. Get ready to transform your backyard or balcony into an open-air art studio and discover the wonder of painting with light.
1. The Classic Nature Photogram: Your Gateway to Sun Printing
This is where nearly every cyanotype journey begins, and for good reason. The natural world is a treasure trove of intricate shapes and textures, making it the perfect subject for your first prints. A photogram is, in essence, a cameraless photograph created by placing objects directly onto a light-sensitive surface. With botanicals, you can capture the delicate veins of a leaf, the complex architecture of a fern, or the soft silhouette of a flower petal.
The process is beautifully simple. On a piece of pre-coated cyanotype paper, arrange your chosen natural elements—leaves, flowers, feathers, twigs, or seed pods. Place a piece of glass or clear acrylic on top to hold them flat and ensure crisp edges, then carry it out into the sun. The areas covered by the objects will remain white or light blue, while the exposed paper will turn a deep, rich Prussian blue after being rinsed in water. This technique teaches you the fundamentals of composition and exposure time.
Pro-Tips:
- Fresh vs. Pressed: Using freshly picked flowers and leaves will result in softer, more ethereal silhouettes, as moisture in the plant can slightly diffuse the light. For razor-sharp, detailed outlines, press your botanicals in a heavy book for a few days before printing.
- Layering: Don't be afraid to overlap different elements. Layering a translucent leaf over an opaque one can create a beautiful sense of depth and varying tones of blue in your final piece.
2. The Glass & Liquid Effect: Painting with Light and Water
Once you’ve mastered botanicals, it’s time to play with how light moves through objects. Glassware is a fantastic tool for this. Unlike an opaque leaf that blocks light completely, glass refracts and bends it, creating mesmerizing patterns and gradients. A simple drinking glass, a vintage bottle, or a textured glass dish can transform an ordinary cyanotype into an abstract masterpiece.
The magic happens in the distortion. The curve of a jar can act like a lens, focusing light into bright spots and casting soft, sweeping shadows. Water adds another layer of unpredictability. Try placing a shallow glass dish on your paper and adding a small amount of water. The ripples and surface tension will create organic, fluid patterns of light and shadow that are impossible to replicate. You're no longer just trapping a shadow; you're recording the physics of light itself.
Pro-Tips:
- Water Droplets: For a stunning, bokeh-like effect, take a pane of glass and spritz it with water. Carefully lay this over your cyanotype paper during exposure. Each droplet will act as a tiny lens, creating beautiful circles of light.
- Textured Glass: Scour thrift stores for old, patterned glass plates or windows. The textures embedded in the glass will cast intricate, repeating shadows onto your paper for a truly unique print.
3. Layering with Transparencies: From Plastic Wraps to Photo Negatives
This technique introduces you to one of the most exciting aspects of cyanotype: tonal range. So far, we’ve focused on objects that are mostly opaque (blocking light) or clear (refracting light). But what about the space in between? Translucent materials that only partially block the sun are key to achieving a spectrum of blues, from deep navy to the palest sky blue.
Start simple. Crumple a piece of plastic wrap and lay it on your paper. Where the plastic is layered thickly, more light will be blocked, resulting in a lighter blue. Where it's a single, thin layer, the blue will be darker. This same principle applies to bubble wrap, sheer fabrics like lace or chiffon, and even things like glassine envelopes. Experimenting with these materials teaches you to think in layers and predict how different densities will translate into shades of blue.
Pro-Tips:
- Everyday Translucence: Look around your home for semi-transparent items. A mesh vegetable bag, a piece of tracing paper, or even a thin slice of citrus fruit can create fascinating tonal variations.
- The Next Step: Once you're comfortable, this technique is your gateway to printing photographic negatives. You can print a black and white image onto a transparency sheet (at any office supply store) and use it to create a proper cyanotype photograph.
4. The Man-Made Silhouette: Finding Art in Everyday Objects
While nature is a boundless source of inspiration, don’t overlook the artistic potential of the objects you use every day. Tools, kitchen utensils, keys, chains, and old bits of machinery have strong, recognizable silhouettes that can make for powerful and graphic compositions. This technique shifts your perspective, encouraging you to see the artistic form in functional objects.
The key here is arrangement and composition. A single pair of scissors can be interesting, but a carefully arranged pattern of several pairs can be captivating. A jumble of nuts, bolts, and washers can create an industrial-age tapestry of shapes. As an artist, I, Goh Ling Yong, often find that placing familiar objects in an unfamiliar context is a powerful way to tell a story or evoke a feeling. A blueprint-style print of disassembled clock parts, for example, speaks to themes of time and complexity.
Pro-Tips:
- Create a Narrative: Try arranging objects to tell a small story. A fork, knife, and spoon arranged on a "plate" of light, or a collection of old keys leading to an invisible lock, can add a layer of meaning to your work.
- Repeating Patterns: Use objects like paper clips, safety pins, or chains to create rhythm and pattern in your composition. The repetition of a simple shape can produce incredibly dynamic results.
5. The Wet Cyanotype: Adding Unpredictable Washes and Textures
Ready to embrace a little chaos? The wet cyanotype technique introduces water before or during the exposure process, leading to beautiful, unpredictable results. By altering the chemistry on the paper's surface, you can create stunning diffusion effects, color shifts, and textures that look more like watercolor paintings than photographic prints.
There are several ways to approach this. You can gently spritz your paper with a spray bottle of water before placing your objects down, which will cause the edges of your shadows to bleed and soften. Alternatively, you can mix in other gentle household liquids. A splash of diluted vinegar can create vibrant yellow-green blooms, while a sprinkle of salt or turmeric onto the wet surface during exposure will react with the chemicals to produce unique crystalline patterns and color bursts. This method is a true exercise in letting go of control and embracing happy accidents.
Pro-Tips:
- Controlled Chaos: Use a paintbrush or a pipette to apply water or other solutions to specific areas of your paper. This gives you a bit more control over where the diffusion effects will occur.
- Soapy Bubbles: Mix a little dish soap with water and blow bubbles onto your paper just before exposing it to the sun. As the bubbles pop, they leave behind delicate, cell-like outlines in the final print.
6. Stencils and Masking: Taking Control of Your Composition
After embracing the chaos of the wet cyanotype, you might crave a little more precision. Stenciling and masking allow you to create sharp, deliberate shapes and designs. This technique is all about intentionally blocking light from certain areas to create negative space or build complex, layered images. It’s the perfect way to introduce graphic design elements into your sun prints.
You can create your own stencils by cutting shapes from cardstock or thick paper—think geometric patterns, lettering, or animal silhouettes. Paper doilies make for wonderfully intricate masks right out of the package. You can also use masking tape to create clean borders or bold stripes. By exposing the paper once with a mask, then repositioning it (or using a different one) for a second, shorter exposure, you can even create layered images with multiple tones of blue.
Pro-Tops:
- Combine with Other Techniques: Lay a stencil down on your paper, and then place translucent objects like leaves or lace inside the cut-out areas. This combines the sharp edge of the mask with the delicate detail of the photogram.
- Lettering: Use pre-made alphabet stencils to incorporate words or phrases into your art, creating personalized gifts or meaningful wall decor.
7. The 3D Sculpture: Playing with Height and Soft Shadows
This final technique encourages you to think beyond two dimensions. While flat objects create sharp, defined silhouettes, three-dimensional items produce shadows with soft, gradient edges. The further an object is from the paper, the softer and more diffuse its shadow will be. This is a crucial concept in truly understanding how to trap shadows.
Grab a small, sculptural object—a wireframe cube, a crumpled piece of aluminum foil, a small toy, or even a houseplant in a pot. As the sun moves across the sky during your exposure (even over just 15-20 minutes), the angle of the light changes. This subtle movement causes the edges of the shadow to soften, creating a beautiful sense of depth and form. You're not just capturing a flat shape anymore; you're capturing volume.
Pro-Tips:
- Time of Day Matters: The angle of the sun dramatically affects 3D objects. Midday sun, directly overhead, will create short, sharp shadows. Early morning or late afternoon sun will cast long, dramatic, and soft-edged shadows. Experiment with different times to see what you prefer.
- Abstract Forms: You don't need a recognizable object. A simple, crumpled ball of paper can become a fascinating study of light and shadow, with infinite crags and peaks casting their own micro-gradients onto the paper. The team at the Goh Ling Yong studio loves this method for creating abstract textures.
Start Your Sun Printing Adventure
The seven techniques above are just the beginning. The true joy of cyanotype lies in experimentation—in the "what if?" moments. What if I use this object? What if I expose it for longer? What if I rinse it with cold water instead of warm? Each print is a small discovery, a lesson in light, chemistry, and composition.
The most important thing is to start. Don’t wait for the perfect materials or the perfect idea. Grab some cyanotype paper, step outside into the sunlight, and begin trapping the shadows around you. You’ll be amazed at the beauty you can create with such simple tools.
