His philosophy is to contribute to science and create awareness on conservation of wildlife, natural resource management and environment protection through his work.

[10] In 2010, a team of eight people including Dhritiman traveled within the Great Himalayan National Park to observe rare peasants and the brown bear.

[12] Dhritiman is one of the very few nature, wildlife and conservation photographers who has dived in frigid waters of the Arctic and Antarctica to capture the aquatic life.

He has also taken iconic pictures of the Snow Leopards in Spiti Valley and in Ladakh which are arguably the first detailed pictorial documentation of the most enigmatic animal in the wild (non-camera trap).

His parents have been a constant source of inspiration since his childhood, so much so that, quite unlikely for his time and upbringing, he was left to himself to choose his career or, rather, follow his passion.

[12] Apart from his parents, Dhritiman has also accredited Moushumi Ghosh, who has been a guardian and second mother and largely instrumental in him becoming a successful nature, wildlife and conservation photographer.

[12] Dhritiman's formative years in developing his interest in wildlife also took place from to his association with Climbers Circle - an institute where he learnt his mountaineering skills and with Prakriti Samsad - a council of nature observers and research activities.

Dhritiman completed his higher secondary from Barasat Peary Charan Sarkar Government High School.

Some of the essential awards are as mentioned hereunder: Dhritiman has co-authored a book with Dr. Asad R. Rahmani called Magical Biodiversity of India.
