Brenizer Method

I’ve mentioned before on this blog that I sometimes create panoramas using my zoom lenses. These aren’t your typical wide landscape panoramas—they can be images of a subject, like a tree, that simply doesn’t fit within the frame provided by the zoom lens. Here’s an example of one of my photos created using this technique.

The Brenizer Method, also known as a "Bokeh Panorama" or "Bokeh Pano", is a photographic technique that combines panoramic stitching with wide apertures to create portraits with an extremely shallow depth of field. This method, popularized by Ryan Brenizer, allows photographers to achieve a look similar to that of larger format film cameras using digital cameras. 

Here is a video explaining this method very well.
