Avoid Softness with Diffraction Limit
Smaller apertures (like f/22) increase depth of field but decrease sharpness due to light diffraction. The **Diffraction Limit** tool at **Online Tool Base** calculates the exact aperture where your specific camera sensor begins to lose resolution.
Known as the Diffraction Limited Aperture (DLA), this point dictates your sharpest settings. **onlinetoolbase.online** calculates this based on your pixel pitch (Megapixels vs Sensor Size). High-res cameras suffer from diffraction sooner (e.g., f/8) than low-res ones.
Why Use This Tool?
Landscape photographers often stop down blindly to f/22 to get everything in focus, unknowingly making the entire image soft. This tool tells you: "On your 45MP camera, don't go past f/10." It encourages you to use Focus Stacking instead of Diffraction for depth.
Key Features
- Pixel Pitch: Calculates the physical size of photosites.
- DLA Output: The f-stop where airy disks overlap.
- Optimization: Helps find the "Sweet Spot" of the lens.
How to Use
- Enter Megapixel Count (e.g., 45).
- Select Sensor Size (e.g., Full Frame).
- Read the Diffraction Limited Aperture (DLA).
- Try to stay wider than this f-stop.
