Composition and Framing

Shallow depth.  It is when the background of the image is blurred but the main image is focused so you can see it.

Symmetry and pattern. This is when the image has a pattern against it in an interesting way.

Viewpoint. View point is looking down onto an image from above.

Rule of Thirds and deep depth field. Rule of thirds is when the horizon  is in the back grounded picture. The deep depth field is when nothing is blurred.

 Framing. Framing is when something else is framing the main image. For instance in this photo the hole is framing part of the fish.

Cropping. This is when you cant see all of the image because most of it is cropped, taken away from the original image.

Balancing element.  Balancing elements is placing your main subject off-centre, as with the rule of thirds, creates a more interesting photo, but it can leave avoid in the scene which can make it feel empty. You should balance the "weight" of your subject by including another object of lesser importance to fill the space.

 

This photo is leading lines. Leading lines is when the image has lines leading towards the main image or photo. This does not have to focused as long as the  lines lead to the image.

Placing your main subject off-centre, as with the rule of thirds, creates a more interesting photo, but it can leave a void in the scene which can make it feel empty. You should balance the "weight" of your subject by including another object of lesser importance to fill the space.
