Hi, everyone.!

I've been wanting to know for a long time how to correctly calculate resolution before scanning. Is there some chart or formuly by which it's done?

and another thing... When I scan I have 2 controls:

Resolution and Scaling

I always scan at 300 ppi and 100% of scaling. I change scaling if I need to enlarge a picture.

How should I properly use these?

Thanks
