What happens to light when the f-stop iris is more open?

Less light is allowed in

More light is allowed in

When the f-stop iris is more open, it means the aperture of the camera lens is set to a lower f-stop number (like f/2.8 versus f/8). A wider opening allows a greater amount of light to pass through the lens and hit the camera sensor. This is critical in photography and video production, especially in low-light conditions, as it helps create properly exposed images.

Opening the iris also affects the depth of field; a lower f-stop can produce a more shallow depth of field, which can be used creatively to emphasize the subject while softening the background. This is an important concept in video production as it influences the overall aesthetic of the image captured. Understanding how the f-stop affects light entry and exposure is essential for achieving desired visual outcomes in various lighting environments.
