Here side by side, is a real world example.
Do you want a smooth background or do you prefer a little more texture?
Love the series James !!! Great examples !!!
This is excellent, thanks so much for posting! I am always looking for the f/4 setting on my 400mm lens, but it just isn't there. :( Maybe some day!! :) Thanks Captain.

Nice James!!!
Thanks for taking the time to do this for us.
:)
Cool series; you can see a change in the sharpness in the top of the piece of wood from aperture to aperture. Where was the actual focal point; in the center of the wood measured both ways?

Thank you for posting this, definitely help.
James:
Great post.. That should be made a "sticky"..

Very well done, James. Your test shots also show the effects of diffraction. The limb is not near as sharp at f/16 and f/22 as f/8.
Excellent stuff James!

If this doesn't help someone understand better why their background looks the way it does I don't think anything will. It just doesn't get any simpler than that!
The side by side shots are very informative, thanks
Well done Frog-teacher :)

Great examples James. Thanks for the info.
Bokeh and the sharpness of the subject at given aperture seems to differ with every lens. Your lesson on the 600mm is as informative as it can get. Thank you.
Very nice examples of the effects. Wanted to add to the comments that it also depends on how far away the background is to the subject. At different background depths each f stop will give a different effect than the ones shown. Things like lighting, blade shape and configuration, lens quality also come into play. My Canon lenses gave a much different bokeh than my Leica or Schneider lenses do as will a Nikon lens. This gives a good general visual representation of how it works. A nice starting point for folks to consider.
