Some photos are focused on one subject, others attempt to capture an entire scene. Sometimes it can be beneficial to set everything aside and focus on a primary task. Becoming lost amidst a sea of clamoring noise disables our enormous potential for focus.
This picture focuses on only the subject. It has a shallow depth of field and simple techniques, portraits are focused precisely on the subject exclusively.
On the other hand, a landscape has no particular focus; it just captures a general theme without an exclusive subject. The entire picture is the subject.
A combination Portrait/Landscape has both a subject and a background general theme. It is less focused on one particular layer, because a camera cannot take in full detail of large changes of depth. Likewise our minds don't focus as well when there is a conflict of attention. Distractions or simple frivolity can consume precious focus, depriving us of our full capacity.
Until next time.
