📷 Photography Basics Series — Part 5 of 5
The Exposure Triangle Explained
Aperture, shutter speed, and ISO are often taught separately.
But every time you take a photograph, all three work together.
This relationship is known as the exposure triangle — and once you understand it, manual camera settings begin to make much more sense.
In the final part of this beginner series, I bring everything together and explain:
• How aperture, shutter speed, and ISO work together
• How each setting affects brightness
• How to balance the three settings
• How they affect depth of field, movement, and image quality
• How to make creative choices instead of only chasing the “correct” exposure
• A practical method for choosing settings in real situations
The exposure triangle can seem intimidating at first, but it becomes much easier once you understand what each setting contributes.
