Approach: macro science. Palette: C, natural.

An extreme close-up macro photograph of a single dried sage leaf, shot from slightly above at a 30-degree angle, with its velvety, silvery-green surface and fine network of veins filling the frame. Tiny trichome hairs and glandular oil droplets catch the light like frosted glass. Soft window daylight comes from the left, giving gentle shadows and a warm, earthy feel. The shallow depth of field blurs a second leaf and a rough terracotta mortar in olive and clay tones behind it. A few crumbled leaf fragments rest at the bottom edge. One faint, vivid electric green reflection glints in an oil droplet as a subtle accent. The mood is calm, focused and fresh, with a natural botanical look. The image has no text and no blue cast, and the tones stay green, brown and amber.
