Detailed Close-Up: Hand Gripping Syringe

Photorealistic macro close-up of a human hand gripping a sterile medical syringe with a capped needle, set against a neutral light gray background. The focus is razor-sharp on the syringe barrel and the fingertips, with a shallow depth of field that softly blurs the background. Render fine skin texture, tiny lines, subtle veins, and reflections on the stainless needle hub and the clear plastic barrel. The syringe shows metric graduations and a small amount of colorless liquid inside. Lighting is even and cool white, emphasizing cleanliness and precision in a clinical, sterile mood.
