For example:

high contrast: Enhances contrast between light and dark areas, intensifying highlights and shadows

shadow: Adds shadow effects

colorful: Rich colors, acts as a quality tag

detailed light/detailed lighting: Detailed light rays, quality tag

light leaks: Light leaks (simulates lens glare in photography); moderate effect in AI

sunlight: Sunlight; moonlight and starlight are also available, though their effects are relatively average

bokeh: Bokeh; creates a soft background blur in shallow depth-of-field shots, similar to blurry background

blurry foreground: Blurry foreground, useful for adding foreground occlusion effects

ray tracing: Ray tracing, quality tag

lens flare: Lens flare; noticeable effect depending on the art style

cinematic lighting: Cinematic lighting; minor effect, largely functions as a quality tag

see-through silhouette: Silhouette created by light passing through translucent objects (e.g., sheer skirts)

strong contrast: Strong contrast, identical to high contrast

light and shadow: Light and shadow, usually adds shadows; essentially equivalent to the shadow tag alone

light particles: Light particles, adds floating specks of light

light spot/floating light spot: Light spots / floating light spots, equivalent to light particles with slightly weaker effect

Reflection/reflect: Reflections on mirrors, water surfaces, or glossy objects

volumetric lights: Volumetric lighting, typically beams of light streaming in through a window; noticeable effect

backlighting/sidelighting: Backlighting / sidelighting, light cast from behind or from the side

chiaroscuro: Chiaroscuro (strong contrast between light and dark), similar to double contrast tags but slightly subtle

dramatic shadow: Dramatic shadow, quality tag

high-key and low-variance brightness scale: High-key and low-variance brightness scale, quality tag

rim lighting: Rim lighting, a photography technique illuminating the subject's edges to create a halo effect

light rendering: Light rendering, quality tag

light-rays: Light rays, quality tag

dappled sunlight: Dappled sunlight, simulates sunlight filtering through trees; great effect
