I use a Wisner 4x5 Technical Field Camera. My films of choice are Fuji Velvia and Provia F-100. I use three lenses: 90mm, 210mm, and 450mm in focal length. This large format system renders great sharpness and clarity of image. The picture taking process usually takes about 30 to 45 minutes of actual camera work with each photograph, but often time’s weather, light and seasonal plant growth requires repeated trips for the optimal exposure.
