One of the most fundamental concepts of photography everybody should understand is the exposure triangle. Consisting of a relationship between aperture, shutter speed, and ISO, mastering this can help when shooting in different, and really any lighting conditions. You can find more in-depth info about Aperture, Shutter Speed and ISO below.

Join me on this journey as we break down the exposure triangle!

What exactly is the exposure triangle?

The exposure triangle is a visual representation of the effects aperture, shutter speed, and ISO have in conjunction with each other, and how they can result in achieving different types of shots. Below I’ve included an example diagram to help guide you through the process.

From this you can see that reducing:

Shutter Speed – means a lighter but more blurred image.

Aperture – means a lighter but shorter depth of field image.

ISO – means a darker but less noisy image.

And increasing these:

Shutter Speed – means a darker but more still image.

Aperture – means a darker but larger depth of field image.

ISO – means a lighter but more noisy/grainy image.

Below you can see a more in-depth understanding of Aperture, Shutter Speed, and ISO.

Aperture:

Aperture refers to the size of the opening in the lens that allows light to

pass through to the camera sensor. It is measured in f-stops, with a

smaller f-stop number indicating a larger aperture opening. By adjusting.

the aperture, you can control the depth of field in your photographs,

determining how much of the image is in focus and creating stunning.

bokeh effects.

Shutter Speed:

Shutter speed, on the other hand, refers to the amount of time the

camera's shutter remains open to capture light. It is measured in seconds.

or fractions of a second, with faster shutter speeds freezing motion and

slower speeds allowing for motion blur effects. By mastering shutter speed,

you can capture fast-moving subjects with clarity or create long exposure.

shots that convey a sense of movement and energy.

ISO:

ISO, measures the camera sensor's sensitivity to light. A lower ISO setting

results in less sensitivity and produces cleaner images with less noise,

while a higher ISO setting increases sensitivity but can introduce grain or

digital noise. By adjusting the ISO, you can shoot in low-light conditions.

without sacrificing image quality whilst controlling the overall brightness of your

photographs.

In summary, mastering these skills within photography is essential when working with different lighting conditions to achieve the desired effect you are wanting to capture.
