Possession of the photographic assets alone does not ensure great images unless the photographer understands the use of correct lighting and has the patience and commitment, to create controlled highlights and shadows with sparkling diamonds.
In technical terms, it is the use of different types of lighting (Soft and hard) both for metal and diamonds in proper ratio and conjunction that is required for high quality images. Fine-tuning the lighting to get glitter of diamonds with smoothness and graduating highlights on metal surfaces, for form and shape. The varying tones of shadows and highlights, on very small surfaces poses the greatest challenge to the photographer.
It is very time consuming and requires a lot of patience and dedication to execute great jewellery photography. Thus I insist once again that great jewellery photography go beyond equipment. Having visual sensibilities are the greatest assets of a professional jewellery photographer.
like in medicine, where you have a specialist doctors who have mastered in Ophthalmology, Oncologist, Ortho etc. Jewellery photographer is a specialist who has mastered the art of jewellery photography.
