Practical exercise
Achieving sharp images every time: try it yourself


1. Focus Check
Zoom in 10x on LCD after shot; verify eyes or key detail is sharp.
2. Aperture Sweet Spot
Shoot at f/5.6-f/8 for maximum sharpness (not widest or narrowest).
3. Mirror Lock-Up
If DSLR, use mirror lock-up + timer to reduce vibration.
4. Clean Sensor
Blurry spots? Clean sensor or get it serviced.
5. Lens Sharpness Map
Test corners vs. centre; some lenses softer at edges.
