Sharpen
The “Sharpen” function attempts to create a crisper and cleaner image with more defined lines, and is useful
for when an image is just slightly out of focus and would benefit from a small adjustment. Note that sharpen
does not clear up out of focus images, so it’s always better to take a correctly focused image (or use EDF if
needing greater depth of focus) before looking to use the “Sharpen” function.
The “Sharpen” function has two different methods.
UnSharp Mark...
- Contrary to it’s odd sounding name, the “UnSharp Mask...” method is actually a sharpen
-
ing method. The name comes from the process it uses to create a sharper image by taking an unsharp positive
image with a negative of the original image and merging the two in order to create additional contrast in the
positive image.
The “Radius” slider refers to the size of the edges to be enhanced. Larger settings tend to cause halos around
edges, so, use sparingly to ensure fine details are enhanced without ghosting. Also, threshold and radius are
related in effect, and thus, lowering one will allow the other to be increased if needed.
