f/4.5 (widest) Experiment in running through five different f-stops (f/4.5, f/5., f/8, f/14, f/29) to demonstrate the increased depth-of-field

f/4.5 (widest) Experiment in running through five different f-stops (f/4.5, f/5., f/8, f/14, f/29) to demonstrate the increased depth-of-field obtained with smaller apertures (larger f-numbers). Note that the widest aperture (f/4.5) has a nice blurred background, whereas f/29 shows all the confusion and distracting details of the greenery in the background. Wider-aperture lenses like the nifty-fifty 50mm f/1.4 or f/1.8 lens will make the background blur even more so, creating what's called a Bokeh. 28 August 2009. The subject here is Rudebeckia black eyed susans from the Cloisters City Park gardens, Morro Bay, CA. Photo by Michael "Mike" L. Baird, mike [at} mikebaird d o t com, flickr.bairdphotos.com; Canon 5D, Canon EF 28-135mm f/3.5-5.6 IS Lens, tripod.
