Sharpen your JPEGs
Reveal delicate details without adding artefacts like haloes and noise
01 Create a layer to sharpen
Go to File>Open. Browse to sharpening.jpg. Grab the Zoom tool, right-click, and pick Actual Pixels from the menu. Hold the spacebar to get the Hand tool. Drag to view the mouth. Click on the Background layer’s thumbnail and press Ctrl/ Cmd+J to make a duplicate layer for sharpening.
02 Incremental sharpening
To sharpen a shot quickly but have some control over the sharpening amount, click on the Quick editing tab. Click on Adjustments. Click Sharpen. To increase the sharpening amount, either drag the slider right or click on the preview thumbnail to increase it in incremental jumps.
03 Adjust sharpness
This Quick Adjustment option is fine for rough and ready sharpening, but it can add artefacts. Click the top-left thumbnail to reset the shot (or drag the slider to 0.) A better option is to click on the Expert editing tab, go to Enhance and choose Adjust Sharpness.
04 Lens blur
Drop the Radius slider to 2.0 pixels. Click and hold the mouse button over the preview window to see the unsharpened version. For more subtle sharpening, set the Remove dropdown menu to Lens Blur. This reduces artefacts such as haloes.
05 Extra options
If your shot suffers from shake-induced blur, try setting the dropdown to Motion Blur, then dragging the Angle wheel to counteract the direction of the blur. Don’t tick the More Refined box; this tends to add extra artefacts. Click OK.
06 Before and after
Your sharpened version of the shot now has delicate details without added artefacts. Click the top layer’s eye icon to turn it on and off and compare it with the original. If it’s too sharp, drop its Opacity to reduce the sharpening amount.
