I altered the recipe of photography chemicals to make pale green & gray prints. Other times I bleached a blue print yellow & printed a second blue print on top of it yielding green, yellow & blue.

Green & Gray Cyanotypes

All works on paper are UNFRAMED unless otherwise specified. Original one-of-a-kind cyanotypes on cotton watercolor paper in different sizes. If there is a price visible, that print  is available for purchase. If there’s no price, it’s currently not available while on exhibition.

Botanical Cyanotypes (All sizes)

Most of my botanical paintings are on 1.5 inch deep gallery canvas. A few are painted on wood panel. They are stretched and ready to hang, with either painted sides or clean white sides and a wire on the back.

Botanical Paintings (Oil & Acrylic)

These botanical paintings mark my return to oils in 2024. Their much slower drying time allows me to do things I cannot in acrylics and their rich, creamy, less flat color appeals to me.

Oil Paintings on Canvas & Panel

All the plants used to make these unique monotypes and depicted in my paintings are native to where I live in northern California.

Native California Species (botanical cyanotypes & paintings

Works on paper are UNFRAMED unless otherwise specified. Each is an original monotype on 100% cotton watercolor paper. *Those originals without prices are not currently available while on exhibition. About the medium: Cyanotypes are a 19th century alternative photographic process also known as blueprints, sun prints or photograms. My cameraless botanical prints are all unique monoprints made using fresh plant cuttings. There’s no film negative, etched copper plate or carved block. Thus there are no other copies. Some are single-exposure and others are multiple-exposure, which yields varying shades of blue or a ghostly overlapped effect from seeing multiple images on top of each other.

Large Cyanotypes:  All 18" x 24" (45 x 60 cm)

Triptychs and diptychs are perfect over a sofa, up a staircase, down hallway or  above a headboard. Most of these works are unframed. Each is an original monotype on 100% cotton watercolor paper.  Most of these sets of original monotypes are loose works on paper which require a mat and frame. Just a few of these are mounted on wood panels and do not require framing. The 18 x 24" prints fit in a 24 x 30" frame nicely once matted.

Diptychs & Triptychs: Botanical

All works on paper are UNFRAMED unless otherwise specified. The Agapanthus flower, also known as the Lily of the Nile, only blooms in summer. These are all original one-of-a-kind cyanotypes on watercolor paper, technically lensless photographs, made using real plants from my own garden. Agapanthus flower only bloom for 2-3 months in summer, so I can only make these prints then. The yellow ones began as blue prints and were toned to change their color. The flowers of my "Delft" series which resemble painted porcelain are actually paintings using light-sensitive photo emulsion with a print made inside their silhouette.

Agapanthus Flowers (All Sizes & Colors)

Painted in a dark room with cyanotype photography chemicals –not ink. I arranged wildflowers atop the light-sensitive painting and exposed it to light to print a pattern inside the painted silhouette.

Delft Garden: Cyanotype Paintings

All works on paper are UNFRAMED unless otherwise specified. These are all hand-printed original photographs using the 170-year-old cyanotype process and very big negatives the same size as the final print. They are of the woods near my house in Oakland, across the bay from San Francisco in northern California. I love how light through fog transforms the familiar into a dreamscape.  I am an early riser, so catching the hushed, fog-blanketed world at dawn is easy for me. This series is ever-growing as I continue to hike the trails every week, the same as I have for 20 years.

Foggy Woods: Cyanotypes of northern California

All works on paper are UNFRAMED unless otherwise specified. Each is an original monotype on 100% cotton watercolor paper.  Reminiscent of sumi ink scroll paintings, the narrow format is perfect for hallways, stairwells, staircases, kitchens, bathrooms and other tight spaces.

Tall & Narrow Cyanotypes

All are hand-printed original cyanotypes, whether landscapes, abstracts or botanicals. Signed on the back. All are matted in acid-free mats with archival linen tape and plexiglass rather than glass to withstand shipment. Some frames are metal and some are wood, but most are white. Please read the details in the description.

Already Framed Works on Paper

The Sunrise Collection (Oil and Acrylic)

These original photographs are each hand-printed using the positive to get a negative–meaning with the dark and light areas reversed. What was originally a dark silhouette of a branch against a morning sky is flipped to look like a night sky with the branch illuminated by moonlight. Different sizes of works of the same name-- take note when purchasing. This series is still growing.

Botanical paintings in all shades of green, mostly in acrylic but some in oil. These are all either on 1.5 gallery wrapped canvas or on birch wood panels all with clean white sides ready to hang without framing.

Green Spring Botanical Paintings

Each abstract cyanotype is an entirely unique work of experimental photography made without a lens, negative or stencil. These exact lines, shapes and shades of blue cannot be recreated as the way the paper was   manipulated by me during exposure was spontaneous and unique. A traditional single-exposure cyanotype yields a white silhouette against a dark blue background on paper painted with light-sensitive chemicals. But instead of creating a white image by blocking light with solid objects on the light-sensitive paper, I use water to block the light, submerging parts of the paper at different angles, creating subtle gradations of darkening blue as I immerse the paper for successive timed exposures under water.

Abstract Cyanotypes

All works on paper are UNFRAMED unless otherwise specified. Each is a unique monotype on 100% cotton watercolor paper.These square original cyanotypes range from 18 x 18" to 22 x 22" to 36 x 36." Take special note of the dimensions if you mean to buy more than one to hang together.
