SUBJECT                                When we talk about it, we expect most of the time that it should be something very obvious or clear or obscured. It is the main point.

How many times do you ask yourself before you shoot? Generally, you should be able to identify it before you actually take your shot.
But sometimes the subject is not very clear, but there should be something to be able to support the subject.
The perspective like which lens you use & the position of the photographer.
Your technical decision are crucial like the shallow depth of field or focal length.

THE FORM                                 The lines, patterns, shapes, texture and colors are what determines the visual structure of an image.

The feeling of symmetry and balance is addressed in the choice of creative decision we make.

THE CONTENT
What is the implied meaning of the story…is it apparent or hidden?

Is it creating emotion, mood or memory?
What is it that catch your attention?
Is there some sort of tension that pulls you to immediately draw your eyes to a certain scenery or object .
Sometimes it is not very instant but rather you identify things or certain expression after an image is critique, in this case post production also affect the way you resonate with the image.
