The Brenizer method, sometimes referred to as bokeh panorama or bokehrama, is a photographic technique characterized by the creation of a digital image exhibiting a shallow depth of field in tandem with a wide angle of view.
Large format cameras use a negative that is at least 4×5 inches (102×127 mm) and are known for their very shallow depth of field when using a wide aperture and their unique high level of clarity, contrast and control.
[1] The Brenizer method increases the effective sensor size of the camera, simulating the characteristics of large format photography.
Shallow depth of field panoramic stitching photographs are sometimes referred to as the Brenizer method, as he popularized it in recent years through his work.
The process requires taking multiple shots of a scene in a manner that allows for later image stitching using a fast lens, generally of a focal length of 50 mm or longer.
