+How to Sharpen Photos
+----------------------------
+First decompose the image into HSV: Colors/Compose.../Decompose. Select
+"HSV" from the list and "Decompose to Layers". This will make a new image
+(close the original).
+
+Select the "Value" layer for editing (so that colors aren't affected). The
+"Unsharped Mask" filter is under Filters/Enhance.
+
+Radius is how many pixels to select, amount is the strength of the filter,
+and threshold allows parts of the image to be ignored.
+
+After applying the filter go back to Colors/Compose.../Compose and select
+HSV again to regenerate the color image.
