Rule of thirds

 Subject is placed off center in an area where the grid lines intersect

Clear center of interest:

subject is clearly identified in a photo, stands out a lot

framing

Natural frame is around subject matter, adds emphasis

filling the frame

Photo is taken very close to the subject, leaving little/no background

repetition

 Repeats elements in a composition, such as lines or shapes

leading lines

Photo is taken on an angle, or has lines leading your eyes to a subject

visual perspective

Showing a sense of space or distance in a composition

Depth of field:

Distance changes the sharpness of different elements in an image

When critiquing a photo what are  the 3 main areas we discuss?

composition, lighting/technical aspects overall mood/impact

1. Composition: Arrangement of subject matter

What element(s) is being utilized to enhance the impact of the photo?

Elements utilized are typically lighting aspects to focus on the subject matter. The position of the subject also changes the impact, and shows the importance of each object.

1. Lighting/Technical Aspects:Color, Contrast, depth of field, saturation etc.

These aspects are the most important part of a photo, as it can change the entire tone or look of the image. 

1.  Overall Mood/Impact

Mood can be changed through various techniques such as color and subject placements. This changes the impact of how an image is viewed by the viewer.
