I put in the word "moreso" because I do realize that if it's in there longer, shadows will come out a bit more, but then you'll blow your highlights way out of proportion by overdeveloping. Shadows stop developing first in the developing process and after a point, they are incredibly difficult to budge without blowing out your highlights.
