People have commented that my images appeared so natural and realistic they felt they could walk right into them. I've always felt the best light for a photograph of architecture or interior design was natural, or available light. My theory is that my efforts should be transparent, no one not in the industry should be able to tell that I did anything to make the spaces look better than they actually are (this includes styling, but that is a subject for another day.) Almost always I only used my strobes, hot lights and bounce panels to reduce the contrast of the natural light to bring the lighting contrast of the spaces I was shooting into line with the limited dynamic range of my film and/or the mechanical restrictions of my camera.
Since adopting HDRI I no longer employ supplemental lighting to alter the presentation of the spaces or structures I shoot to conform to these restrictions. I work with the available light exclusively and get results that are on par with any image created with extensive lighting and hour upon hour of (sometimes) superhuman effort to maintain a realistic representation of the space, without unnatural shadows or odd reflections.
The end result is photographs that capture the character and emotional context of the spaces with unparalleled fidelity to the human perception of the space.
