Located at the front of your camera, it allows specific amounts of light into the camera to create a sharper, accurate image.

For example in the left photo, there was a larger aperture used, which gives more attention to the image that is closes to the camera. It gives it a sharper focused look. Whereas the photo on the left is used with a slightly smaller aperture where the camera focuses on the whole of the image rather than one picture.

This could also be known as depth of field, which is the distance between the nearest and furthest objects giving a focused image. This can create much more eye catching images as it can make a specific object look much sharper, and giving it more of the attention than the objects around it in the background, while bringing out details within the object it is more focused on, like the tonality.

In order to change the option on your camera of the Aperture, it is visually seen as “F–“. With a scrolling option at the front of the camera as seen in the image, which allows you to have a higher or lower aperture option.

Aperture is the adjustable lens opening that controls the amount of light allowed into the camera. the smaller the aperture the greater the depth of field. Whereas, a wide aperture gives you a shallow depth of field which leads to only the foreground is sharp.  A narrow aperture gives you a deep depth of field which means everything is sharp.

What is Aperture?

The aperture controls how much light enters the camera. It also controls the depth of field. Aperture is the adjustable lens opening that controls the amount of light allowed into the camera. Learning to properly adjust these three settings based on your location and subject is essential for capturing good exposures.

We tested using the aperture by taking pictures of things we collected from the beach, rocks, shells, flip flops, and other objects. Using two types of set up, first was an infinity table which gives the illusion of white space in the background of the image. We placed coloured jell sheets in front of the lights changing the colour of the images. Our second set up was using more natural light, with a white backdrop.

What is depth of Field?

Depth of field is the distance between the nearest and furthest objects giving a focused object that are in acceptably sharp focus in an image captured with a camera. The lower the depth of field, the closer you are to your subject.

Here is an example of different depth of field where on the right the background of the image is out of focus and the flower is in focus.

How does it function?

Aperture is like the “pupil” for your camera system. It opens and closes to alter the amount of light that passes through.

How does it effect depth of field?

Depth of field determines which parts of your photo are in focus and aperture lets you control that. A wide aperture gives you a shallow depth of field (only the foreground is sharp) A narrow aperture gives you a deeper depth of field (everything is sharp).

For these images we used a narrow aperture giving it a deep depth of field to ensure the whole image was in focus. If we had widened the aperture the background would be out of focus and the objects would still be clear.

In this photoshoot I experimented with aperture, with some images resulting in being darker then others. In some of these images I used coloured gel sheets to create a colour filter over the images, holding the sheets over the lights.

what is depth of field?

As a result, depth of field (DoF) is the distance between the nearest and furthest elements in a scene that appear to be “acceptably sharp” in an image. The distance between the camera and the first element that is considered to be acceptably sharp is called DoF near limit.

In the image, if a lot of the image is being focused on, this is called large depth of field. In the image, if a small amount of the image is being focused on, this is called narrow depth of field.

I used ‘shift’ and ‘X’ to reject the images that I didn’t want to edit as they were out of focus or over exposed.

I have filtered out my rejects by filtering to only show the flagged photos.

You can compare images next to each other by selecting two and then clicking ‘Compare View’. You can then zoom in on them by clicking on an image and moving about.

You can also compare more than two images in ‘Survey View’, however you can’t magnify the images in this mode.

I RAG rated my images from green to red. Green is the images I will definitely edit, yellow is alright, and red is the least best images out of my final selection.

I edited my best image adding contrast, vignette, texture etc. to add depth and make the image more interesting. This is the original compared with the edit.

More Basic Edits

How to export images from Lightroom:

File – export – ‘export to: same folder as original photo’ – tick ‘put in subfolder’ – ‘Blog’ – image sizing – tick ‘resize to fit’ – ‘short edge’ – 1000 pixels.

Do the same for the ‘print’ folder but choose 4000 pixels.

Final Image

What is it?

A shutter – is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene.

shutter speed – It’s the speed at which the shutter of the camera closes. A fast shutter speed creates a shorter exposure which is the amount of light the camera takes in and a slow shutter speed gives the photographer a longer exposure. 

Using different levels of shutterspeed we then did a shoot of our own where one person was taking the photo and the other moved around trying to avoid the camera. This meant the photogropher had to set their shutter speed depending on the model, as they were moving fast, to capture the focussed image.

JOHN BALDESSARI

John Baldessari was an American photographer known for his work featuring found photography and appropriated images. Initially a painter, he began to incorporate texts and photography into his canvases in the mid-1960s. In 1970 he began working in printmaking, film, video, installation, sculpture and photography. 

The three balls

One of his most recognised shoots involved photographing three balls being thrown into the air attempting to capture them in a straight line. In this shoot no two photographs are the same because of variables such as changes in wind speed and the natural lighting. Through this process, he captured a divide between the thought of an idea and its execution.

My attempt

Inspired by his collection called – Throwing Three Balls in the Air to Get a Straight Line – We tried to capture some similar images.

Camera dodge game

To experiment with the effects of changing the shutterspeed we played a game where one person has the camera and the other tries to dodge the camera whilst the photographer attempts to capture them.

Here are the results from my recent studio shoot exploring the use of aperture to create different effects.

Here is a diagram to remind you of the effects that aperture creates:

In this shoot, we chose to show the results of using different apertures to take the same images:

The following images are in the same order of aperture (f5.6, f16, f36), but in these, the objects were arranged moving away from the camera, in order to show the clarity in aperture levels. This is drawing on the idea of lining up 22 eggs away from the camera, and by increasing aperture from lowest to highest, seeing an increase in the number of eggs that are in focus. Here we of course didn’t use eggs but instead the objects we were already photographing. You can see this effect was achieved as in the first image (with a low aperture) a low number of the objects are in focus, but in the final image (with a high aperture) all the objects are in focus.

When I first opened Lightroom Classic, I created a collection to put my photos inside. I made a sub-folder for the photographs we had taken in the studio, and began the process of editing.

Using the picker tool, I selected my best images that would be eligible for editing, ones with the least blurring, highest resolution, and good framing. The rest would be discarded as the set was obstructed by either someone else or the shutter when the shutter speed was set too high.

this is annoying

The photographs with the white flag in the top left were the ones that were kept, whilst the ones with the black flag were discarded.

These were the photos I was left with. My plan was to then experiment with editing to give them more colour and detail.

These were the three edited images I was left with. I increased the vibrance in each one to bring out the blue hue of the background, and messed mainly with the exposures and contrasts to create three similar pieces that could work as a tryptic.

During my GCSE’s I used Lightroom for my photography, so I’m familiar with the tools and layout of Lightroom Classic.

Aperture is the opening of the lens through which light passes to enter the camera, aperture can also be described as the adjustable lens opening that controls the amount of light allowed in the camera
