Learn what diffraction is in photography and how it affects image sharpness. A practical guide by Capture Canvas for better photos.
At Black Canvas Photography, I often tell my students that photography is not just about light… it is also about how light behaves when it passes through your lens.
Today, I want to talk about something many beginners ignore, but professionals quietly respect, diffraction.
When you close your aperture too much, thinking you will get the sharpest image, something unexpected happens. Instead of becoming sharper, your image actually starts losing detail. That softening is not your mistake… it is physics. Light bends when passing through a very small opening, and that bending reduces sharpness. That is diffraction.
So what should you do as a photographer?
Don’t blindly shoot at f/16 or f/22 every time. Learn to balance depth and sharpness. In most cases, your lens performs best somewhere between f/5.6 and f/11. That is your sweet spot.
At Black Canvas Photography, we don’t just teach camera settings. We train your eyes to understand why things happen. Because once you understand the “why,” your photography changes forever.
