From Manila, he moved to Davao in 2003 to conquer Mount Apo (Philippines' highest peak) and has been climbing an average of thrice yearly since then. He has worked as official photographer for the Department of Tourism Region XI, before opening his own photography studio. He is an avid mountaineer who has scaled many peaks around the country (and in Kota Kinabalu, Malaysia), a spelunker who is into cave photography, a diver and a trekker. Rhonson's skills vary from portrait, landscape, fashion, sports, aerial, product, food, wedding to photojournalism. He has honed his eye in film photography and darkroom processing before moving on to digital photography, so he remains partly purist by heart.
