Subject Isolation

Isolating a subject is a matter of using the appropriate aperture , in the top image I used f2.8 to isolate the single purple flower so it would stand out even more from the blue ones, in the lower image I used f5.6 to try and maintain the entire flower in focus, it helps a lot to not have a busy background so the bokeh is as pleasing as possible and this helps with the isolation, extenders and extension tubes come in useful to get in tighter with your lens and a wider aperture lens is better for isolating your subject, this can be used for taking people portraits also.
