laboratory test tubes science research
Prompt
Photorealistic close-up of several clear glass laboratory sample vials with black ribbed caps standing in a brushed metal test tube rack, some empty circular wells visible in the foreground. The vials catch a cool blue scientific glow from below and the right side, with a deep black laboratory background fading into shadow. Labels are generic frosted stickers with soft abstract line markings, no readable text. Mood is precise, sterile, and research-focused, with a restrained palette of icy blue, silver, black, and transparent glass highlights. Low-angle macro composition, central vials sharp and rear vials softly blurred, strong contrast, natural reflections, shot on a 100mm macro lens at f/2.8 with shallow depth of field.
