Lens sharpening

Get to know your lens.

A lens does not resolve detail equally everywhere in the frame. Phorevia can measure suitable edges in a photograph or chart capture, create a sharpness profile and use it to guide correction on your photographs.

Correction on — Lens sharpening example — **Nikon interior · photo-measured sharpness profile** The same photograph with correction off and on, using a profile fitted to nine accepted edge samples in this image. This is a photo-calibration example, not a controlled chart measurement of the lens.

Correction off — Lens sharpening example — **Nikon interior · photo-measured sharpness profile** The same photograph with correction off and on, using a profile fitted to nine accepted edge samples in this image. This is a photo-calibration example, not a controlled chart measurement of the lens.

The profile was measured from this photograph using Phorevia's photo-calibration workflow. It can include focus and motion softness; it is not a claim of chart-measured lens performance.

The detail view uses the same 960 × 640 source-pixel rectangle on both sides, starting at (2520, 1680). Its display size adapts to your screen.

A closer look

The tools behind the result.

Choose a calibration source

Use a suitable photograph, or save and print the calibration chart and photograph it with the lens and settings you want to characterise.

Measure and review

Analyse the chart samples, inspect the fitted result and save a usable lens sharpness profile.

Apply the profile

Select the appropriate profile and inspect its correction on real photographs. Keep the capture conditions in mind when choosing a profile.

Look across the frame

Compare corners and centre at detail scale. Watch for excessive sharpening on high-contrast edges as well as changes in texture.
