    f/5.6 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.

      Great series to show what the f/stops will do. All you have to do is check out the leaves and it really enhances your demonstration.

      What a vivid difference (and a great demonstration).
      The flowers just pop off the page using this setting.
      It's one thing to read about a lesson like this, but it is
      unforgettable when seeing it laid out like you've done here (visually).
      Thanks, Mike.

      Ah ha! you have caught the bug for Rudbeckia's! All mine have wilted now since it has been 6 months of blooms.

      Mike, thank you for posting this experiment. It makes a lesson that can be difficult very clear. Wonderful composition and the color is gorgeous.
