disclaimer = some technically challenged photos below but chalked up in the name of learning ; ).
After learning of a process to boost the narrowness of the depth of field of an image this morning using panoramic stitching of multiple overlapping images taken with a longer lens instead of shooting the same field of view in one shot with a wider lens, I had to experiment as soon as possible.
I've shot panoramics with longer glass before to increase level of detail and angle of view, such as this wide rock art panel at the Horseshoe Shelter site last year.
I've also contemplated the benifits of a long lens wide open in different situations, but never put two and two together.
Below the first image is a panoramic of 16 overlapping images taken with my 40-150mm at 40mm (x2 crop) and wide open at f4. Stitched with an old version of Hugin (as was the above image), please excuse the parallax errors, exposure variences, and mostly a gross lack of scenery.
Now for the "control", I changed to my 14-42mm lens, took a sip of the drink, and shot at 14mm and wide open at f3.5,
In spite of a lower aperature, much sharper throughout, less bokeh, and broader DOF.
I'm sold on trying this on an actual subject of interest or a good friend standing somewhere scenic this weekend!

Long but scenic is my commute. I've often wanted to stop every fall and winter to shoot this stretch. I finally had a few extra minutes to stop for a change, though not the same as I've always invisioned from the higher perspective of the roadway. A couple "test" photos along the Provo River before the next storm finishes off all the leaves.
