고대 숲에서 희귀 버섯을 연구하는 식물학자

Expert portrait artist, I need your guidance on creating a hyper-realistic portrait of a passionate botanist in his forties, kneeling in an ancient forest, examining rare mushrooms with a magnifying glass and tactical flashlight. His expression shows studious fascination. Include rich texture details: dew-fringed ferns, mossy bark, airborne spores. Use cinematic backlighting, close-up composition, shallow depth of field. Please advise on achieving this realism.
