The River Crossing’ – a sculpture by Jane Hart, manufactured as part of a set by Danbury Mint in the 1990’s. 

Photo made under studio flash, – two reflector umbrellas, placed directly above the item. Camera was a Nikon Df, with a Tampon 28-70mm f/2.8 portrait lens. Because this lens has a shallow depth of field, (it’s designed to be a portrait lens). I selected a tiny aperture, just f/22 with a focal length of 70mm, to produce sharpness throughout the image. For reciprocity,  that required an ISO of 1600.  

The shutter speed under studio flash is of little importance,  for the flash duration more or less determines the exposure time, 

(…so long as it’s under 1/250th sec – or the shutter will be faster than the flash and will obscure part of the image, and to slow a shutter speed will admit ambient light, which can be useful when using flash outdoors, or for fill-in, but not usually in studio, where the flash would usually be the only source of light).  

So shutter speed for this image was 1/125th sec.
