USER MANUAL HASSELBLAD HTS Item no 3043400 What is it The HTS 1 5 is an accessory for H system cameras that greatly expands their usability both technically and creatively It works by allowing a lens to be moved in two different ways to meet some challenges typically found in professional photography It is compact simple to use and can prove to be an invaluable aid in certain situations The HTS 1 5 adapter is mounted between the lens and the cam era body and by way of the databus connections automatically conveys data to ensure the optimum in convenience and accu racy of exposure This information is finally stored as metadata with each file that can then be accessed in Phocus And it is in Phocus that DAC corrections automatically take into account all tilt shift and rotational movements as well as a long list of specific lens data This ability unique to Hasselblad ensures the exceptional quality produced by the HTS 1 5 What does it do The HTS 1 5 primarily solves problems but equally well pro motes creative opportunities to provide the photographer with an almost invaluable tool Problem solving would be most obviously beneficial in architec tural work close up product photography and certain kinds of documentation for example Creative opportunities would cover almost any area of photog raphy where a fresher approach is required regarding selective focus and or perspective manipulation How does it
