Sharpening your photos: try it yourself
1. Masking Trick
In Lightroom, hold Alt/Option while sharpening; white = sharpened areas.
2. Subtle Amount
Increase sharpening gradually while viewing important detail at 100%. Stop when edges look clearer, then back off if halos, crunchy texture or noise become obvious. There is no universal correct percentage.
3. Radius for Detail
Low radius (0.8-1.0) for fine detail (eyes, text).
4. Noise Caution
Try the same sharpening on a clean low-ISO photograph and a noisy high-ISO photograph. Notice how sharpening can make noise more obvious, so the noisier file may need a gentler setting.
5. Output Sharpen
Apply extra sharpening only when exporting for web/print.
