APERTURE : Understanding Exposure in Digital Photography

On our series of demystifying photography, we’ll be looking at one of the three cardinal factors that determine exposure in photography; which is Aperture. The other two are ISO and Shutter speed. Before we go ahead, it’s advisable¬†we have a good knowledge of the structure of a DSLR camera

What Is Aperture

Aperture can be defined as an opening in a lens through which information in form of light travels into the camera body/structure. This could vary in size. The larger it is, the more light that gets into the camera.

Aperture Size

The size of the aperture can be controlled by the Iris. In Digital Photography, the aperture is measured in f-numbers (for example f/8). The f-numbers or f-stops can be used to describe how wide or narrow the aperture is. A smaller f-stop means a larger aperture while a larger f-stop translates to a smaller aperture. This is another area photographers find confusing but once you understand the ideology, it sticks.

Below a graphic representation of Aperture.

Depth Of Field.

We can hardly discuss Aperture without making reference to Depth of Field. Depth of Field can be defined as the amount of your shot that is in focus. A large Depth of Field means that most of your image would be in focus. This can be produced using a small aperture (large f-number/f-stop) such as f/16.

Large Depth of Field
Large Depth of Field (Large F-number/Small Aperture) F-stop f/13 Exposure time 1/160secs ISO 160

A small or shallow Depth of Field can be seen as an image with only a portion of it in focus while the rest of it remains blurry or fuzzy.

Shallow Depth Of Field
Shallow Depth of Field (Small F-number/Large Aperture) The image was taken at the LetstalkphotographyPH meeting f-stop f/1.8 Exposure Time 1/200 secs, ISO 1600 Focal Length 50mm Subject Distance 2.5m Metering Mode Centre Weighted Average No Flash

DSLR Lenses are manufactured to have specific values on how wide or narrow the aperture can get. The lens specifications usually state the largest f-stop and the smallest f-stop. A lens with a maximum f-stop of f/1.2 is considered to be a fast lens because it allows more light to pass through compared to a lens with a maximum aperture of f/4.0

Collaborations And It’s Relevance Among Creative Professionals

As Creative Professionals, we have a moral obligation to constantly hone our skills if we want to remain relevant in the Industry. Before we go further, let’s start by defining some key terms in this Editorial.

Who is a Creative?

A Creative is an artist. This individual is someone who sees the world slightly differently from others. Examples of Creatives include but not limited to musicians, painters, stylists, make-up artists, and Photographers.

Who is a Professional?

A Professional can be seen as a member of a profession or any person who earns a living from a specified professional activity or craft.

So simply put, a Creative Professional could be seen as a creative specialist/person who is employed for the extraction of skills in creative endeavours


A Collaboration could be seen as the act of working together with someone or a group of persons to achieve something.

Let’s get down to our clime. As a Creative Professional, there is a burning¬†desire to create your portfolio. This portfolio gives an insight into your craft and how proficient you are at it. In the recent past, there has been an increased number of collaborations among creatives; especially photographers, makeup artists, stylists and others to create images for the sole purpose of advertising online; especially on social media to help project one’s business.

Collaborations yield exceptional results when there’s a prolific combination of specialties from the departments involved. Like the saying goes, “A team is only as strong as the weakest member“. In summary, it’s expected that everyone is meant to contribute their best to ensure outstanding results are produced. Collaborations bring together Creatives who have fresh ideas and diverse concepts at the planning stage so a great deal of humility and mutual respect is required of all members to ensure the outcome is successful as everyone sure has a valid point to add.

Finally, collaborations involve working together as a team with a common goal/objective. Tasks are shared which every member executes and gets back with results. Working in isolation is only a sure path to disaster. Success also tastes better when shared.
