I did have some images I was going to do a post on this very subject but I will use one of them here for you.
This image is somewhat special. it is a blending of multiple images to show the detail change by simply rotating the object to the film plane.
What we are seeing in this block setup is the change of detail from one to the next.
Ultimately something like this will be most desirable for levels of detail visible.
As for direct vs bounce you will need to play with it to see. Some blanks love direct and others bounce.
With the right angle of lighting to the right angle of the pen all of those tricky details will come flooding out.
Hope this help.
