Aperture

 The rate of the exposure is how open the lens is, this determines how much light hits the image sensor. The aperture also decides and affects the depth of field for an image, affecting what is in focus. 

Pros 

Cons 

The freedom in choice to blur a background or keep everything in focus.

A very low aperture can result in a super bright photo. 

Can capture detailed images.

A very high aperture can result in a super dim photo. 

Low aperture can reduce motion blur 

The corners of a photo can be dark 



for this design I decided to take the same photo twice adjusting the aperture as much as visibly possible. As you can see in the first image the girl is very clearly seen and you can see the details of her hair even the smaller ones that are lifting in the wind, with a very blurred background but as she is the only thing in the foreground, she is completely visible drawing the attention of the viewer. The audience focus on her and the fact that she is looking out and what she is doing or wearing this contradicts to the connotation and denotation of the second image with a difference in aperture levels.


This second photo shows the same girl looking into the same distance however with a complete re adjustment of the aperture as the background is completely in focus from the small details of the window the clock and the tree compared to the foreground of her shoulder and her being completely blurred not being able to tell much detail, however this is not needed as the audience are paying attention to what she's looking out to, with a partial denotation in the back of their mind reminding them that they're looking at the same thing somebody else is, what this does is make the photo more interesting and has more meaning to the location as it probably means a lot to the person viewing it  [in this case the girl to the left of the screen].

Triptych

Image
  This photography style includes three consecutive   images   that together create a story board of events. One photo may not make as much much sense as when it is put with the rest to finish the story.  Pros  Cons  The possibilities increases from one snap shot to three, meaning its easier to show the movement of a subject.  If the photographer isn’t careful then viewers may be confused at the actions between the images and not put together the motion so well. Viewers can admire the media pieces for longer and have more to denote.  Some may feel limited to only three images.  To show different elements to the same subject. If separated, one photo may not make sense.  These three images when placed together in the correct chronological order create a story. The first part of this story shows 2 girls in a conversation with neither of them looking too happy, the girl on the right is seemingly talking while the girl on the left seems to be...

Digitally manipulated

Image
  Not all photos come out as planned, this is where digital postproduction manipulation takes place. This process means that an editor makes changes to the images as the final product to make the image appear differently   Pros  Cons  If something goes wrong with the photo it can be fixed.  Changing one thing may effect the rest, like brightening the image may appear pixelated. Editing can make the photo prettier and more appealing to those viewing  If caught some audience members can be angry and unpleased  If the location of shooting was limited, some people may never know. The morph of reality to gaslight others may come around to make other things seem fake  This first edit is of two girls lying down on the grass this photo was taken during sunset in the middle of a field, therefore there is not much light and needed an extended shutter speed. Both girls are looking directly into the camera with the edited version showing one girl standing out...

Event photography

Image
  The use of high-quality images during an event is to capture the importance of the occasion and the business of the activities. To fulfil  a number of  requirements like remembering the  memories, or  getting natural moments in candid photos of movements.  Pros  Cons  Photographers don’t need to instruct anyone on what to do as subjects are already taking part  Not all attendants will want to be photographed. There is often multiple things happening at once making images more interesting  If in a dark room, then lighting can be an issue. If there is lots of subjects, then it can be quick and easy to continuously find things to photograph.  It is easy to miss a good moment on film and not have another chance.  This first image shows a girl looking up with party lights all around her surrounded by multiple different people, the audience can tell that this is a party from the context clues and the multitude of others around the ...
