深紅の顕微鏡背景に集まる赤血球

Several red blood cells (erythrocytes) in sharp focus at the center of the frame, moderately sized, showing their characteristic biconcave disc shape with detailed texture and natural reddish color. Three to four erythrocytes clustered together in the central area, all in crisp focus. The remaining erythrocytes are scattered across the background, softly blurred with a shallow depth of field, creating a gentle bokeh effect. Muted, dim lighting — not overly bright, with soft diffused illumination that is easy on the eyes. Dark, deep red background tones. Scientific photorealistic style, microscopic photography, macro lens, low-key lighting, cinematic depth of field, restrained color palette, no harsh highlights.
