laboratory test tubes science research
Prompt
Photorealistic macro close-up of several unbranded glass laboratory test tubes and graduated cylinders standing upright on a clean white lab bench, filled with transparent red and cobalt-blue liquids at different levels. Compose tightly with one central red sample sharply in focus and surrounding tubes partially cropped and softly blurred, creating layered reflections, refractions, tiny bubbles, and glass distortion. Use natural-looking cool laboratory light mixed with subtle warm highlights from the background, a calm clinical research mood, and a palette of clear glass, white, deep crimson, blue, and muted amber. Shot on a 100mm macro lens at f/2.8, shallow depth of field, realistic reflections, documentary science photography style.
