LAB Inversions

I am often asked about my technique for obtaining creative effects using LAB color adjustments in Photoshop. While the theory behind this set of techniques is a bit complicated, there’s nothing complex in practice about using LAB color adjustments creatively. I’ve written about these techniques both in The Photoshop Darkroom and also in The Way of the Digital Photographer.

To make your life easier if you want to experiment with creative LAB, I’ve also written a Photoshop action that you can download for free using this link (check out the included readme file for installation instructions). This action essentially presents the possible LAB channel adjustments as a palette of possibilites for you to choose from when making your creative choices, and I’ve used my own action—Photoshop’s word for a macro—to create the different creative versions of the images shown here.

For example, with the cone flower (Echinacea) shown here, last year I planted it in a pot on the porch, assuming it would essentially be an annual. Somewhat to my surprise, it has come back strongly for a second year in its pot. We water it with recycled water—such as unfinished water bottles started by the kids. The young flowers are translucent and striated, like the day-old blossom shown. As the flowers mature, the petals become opaque, and a mono-colored shade of pink magenta.

The miracle of LAB channel inversions and adjustments leads straight to the alternative, colorful versions you see below:

I plan to print these images as a quadtych, with the four images arranged in a sequence, pairing the original version on white with the Inversion on White, and the two black versions together.

Where: This is an online webinar via Zoom. Zoom authenticated registration and a tuition payment of $29.95 are required for enrollment. Seating is limited. Click here to register now.

Also, Harold will explain how to use LAB for creative sharpening effects by using only the grayscale information in an image, thus avoiding unsightly and over-sharpened color.

Harold says, “All-in-all, you get more ‘bang for the buck’ with creative LAB than any other aspect of Photoshop, but at the same time LAB is surprisingly underused and underrated. I always enjoy teaching this subject, and tell my students as the class begins to hang on, it is going to be an exciting ride!”

Flowers on Black versus an Inversion

Orchids on Black © Harold Davis

Orchids on Black © Harold Davis

The image above, Orchids on Black, was created by photographing the flowers on a black background, with a bit of enhancement in LAB color. Flower Magic on Black, shown below, was photographed on a light box. The background of the image was converted from white to black using an LAB inversion of the L-channel.

LAB Color Variations

From the block-print-like flower composition on white (shown second from the bottom of this story), I used LAB color to apply individual color channel adjustments to create the eight variations shown in the Photoshop collage (immediately below). To learn how to do this in detail and step-by-step, check out my complete online video training course Creative LAB Color in Photoshop. This course provides unique and detailed information, substantially the result of years of research, work, and experimentation on my part, that you can find nowhere else.

I created the original version shown below using my Photographing Flowers for Transparency technique on a light box. The channel adjustments in the collage (above) use variations that do not involve inversions of the L-channel, which swap whites for blacks (and blacks for whites), and (in this case) create a black background effect. An example of an L-channel inversion of the block-print flower image is shown at the bottom of this story.

Making a Flower Block and LAB Collage

Last week I photographed a medley of flowers from our garden on the light box, with one result shown in a previous story. The flowers together formed almost a kind of color block print:

Running the block print image through LAB color adjustments, I couldn’t help enjoy the variations, and constructed an eight-panel collage. Each panel represents an LAB channel equalization or inversion, all based on the original flower block. Click here or on the collage to view it larger.

Low Geostationary and Decaying Orbits around the Clematis Inversion

I spent a few days doodling and noodling with flowers, first on the light box for transparency and then with LAB inversions in Photoshop, and Low Geostationary and Decaying Orbits around the Clematis (shown here as an inversion) is one of the images I came up with!

Inversions (and lions, and tigers, and bears, oh my!)

From the humble Echinacea photographed for its delicate petals, the miracle of LAB channel inversions and adjustments leads straight to the drug-crazed and colorful versions you see here (just as they used to think soft drugs led to harder ones). Poppies will put them to sleep, and their little dog too! Even though the Echinacea is a simple, calming herb, and it is certainly no relative of Morpheus or his fearsome descendants.

I plan to print these images as a quadtych. In other words, four images, with the original Echinacea and the three shown here.

What a great word “quadtych” is! Almost as nice as “quidditch.” I often create sequences using the creative power of LAB, and these seem like a natural for printing quadtychs—and even pentaptychs and hexaptychs!
