portrait photos:

This photo I took not only has rule of thirds but has a blurred background that helps empathize James (the guy in the photo/model/subject) and by exposing the photo in photoshop, and even though James has a busy background behind him the lines of the fence all lead to him (whose in the foreground of the photo).
 
This photo is a good representation of contrast because of Strahinja (the guy in the photo/model/subject) is wearing a dark jacket and hoodie that is has a decent amount of colour difference compared to the plain grey/white door behind him.

shutter speeds and aperture size

Slow Shutter Speed
Slow shutter speeds if used with panning can create motion blur, panning is done by focusing on a single moving object/person while they are in motion, if done correctly it can produce a feeling of movement in the photo.

Fast Shutter Speed

Fast shutter speeds are good at catching in-the-moment photos, used for high speed movements, commonly used for freezing an action.

Wide Aperture
A wide aperture makes the foreground objects sharper and the background all blurry, its a good method of emphasis and is useful when a background is distracting or boring. (no one likes boring backgrounds imma right?)

Narrow Aperture

a narrow aperture keeps objects in the photo crisp and detailed, this makes it good for landscaping and technically any other type of photo. 

type of aspects in photography

 

This photo shows the leading line, the leading line in this is the boardwalk, the board walk makes the viewer's eye move down the photo. The reason I choose this photo is because not only is it a good representation of  leading line I also like the colour  scheme, the pale colours give the photo an almost "vintage" look.  

This shows framing in a photo, the frame is the window , the window makes your eye automatically look at the landscape outside. The reason I chose this photo is because I loved the vibrant colours and  I find its a great representation of depth and space.

This represents the rule of thirds, the rule of thirds in this photo is the fact that the bee is on/around  the right vertical line. The reasons I chose this photo is that I really like the use of  shutter speed to show the blur in the photo, the blur actually helps show the rule of thirds in this photo (this is my personal option).

This photo describes interrupted pattern. I though that it was a good representation of pattern because it shows the basic idea of a interrupted pattern, a repeated and consistent design that remains that way until a object (or person intersects it and discontinues it.  

This photo is a type of "fill the frame", this means that a majority of the screen is filled with the image you want to emphasize. In this image the owl is filling the frame and  making it so there is more positive space then negative space, the negative space in this case is the blurred background.
