I have just discovered this site few days ago.
Like to share this with everyone. Looks like small aperture is great:
1 For portraits in studio, F8 or F11 so that various parts of the body can be in sharp focus, as some part of the body is nearer to the cam than others.
2 For outdoor portraits, my favorite is F13 and F16 to balance fill-flash and ambient light. Also, to be able to have the background sharp enough to recognise the place. Otherwise, you might as well shoot in a dumping ground and use F2.8 so that you do not see what's behind.
3 Close-ups like flowers, my choice is F16 so that every part of the flower is sharp, but still get good bokeh in the background.
4 Landscape - here again I use F16 so that foreground and background are in sharp focus.
So, looks like not much uses for those huge barrels that are also known as phallic symbols in these areas. That is why I use small lenses and I call myself SmallAperture.
