In the Lightroom exporting menu, there are options to sharpen for screen and print.
What are the differences between the two? And how does each setting actually sharpen the image? And finally what is the benefit of this feature over manually sharpening in the "develop" phase of the process?
Update:
After several comments I have decided to edit the question to clarify why I have asked it and why previous questions on similar topics have not answered it.
I am after the values it uses and how it defines these values when sharpening, so that if it is too much or too little I can replicate it manually.
