Background blur / bokeh on a natural subject: variation with aperture - OMD EM10ii + 45mm f/1.8.
Effect of aperture on background blur / bokeh effect on a natural subject - OMD EM10ii + 45mm f/1.8. Successively taken shots f/1.8, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16 and f/22 (except that f/2 was actually taken last for completeness but I placed it second in the column of photos where it should go). This series shows well the compromise that you might have to make between getting an aesthetically pleasing blurred background effect and not actually having parts of the subject out of focus. This honeysuckle flower has petals pointing to and away fro the camera and, with the lens wide open, parts of the flower are out of focus. This in itself can be a distraction. In this case it seemed best to focus on the buds / seed pods and the most detailed parts of the picture to get a pleasing shot. It is not until around f/4 that the whole flower is in decent focus but a lot of the bokeh effect is lost by then. This would not be a problem if the subject was flat with all parts equidista...
