I experimented this with few photos, here you can see the outcome. Moderately used this is a great tool to use, First photo is the original.
in the last photo as it was sharpened too much it came granular.
In these the difference is significant and worth the trouble – the detail are much more clear. Also I did add a little contrast too 🙂
