dave said:I took some photos this morning and shot this Crepe Myrtle 'Natchez' using two different aperture settings. Everything else was identical:

Notice the background change as the aperture opened up.

This is probably a little pedantic and inconsequential, but I think it's important on at least some level to note that when you change the aperture value either the shutter speed or the ISO value (or both) need to change to get a similar exposure.

And that's what happened here, too:

f/5.6, ISO 100 , shutter speed 1/200
-vs.-
f/20, ISO-500, shutter speed 1/83
