D 300 sharpening.

[Towershot]

I am doing a few shots indoors for a friend to put in an advert in the local newspaper.

It is indoor shots ,in a ballroom, at around 7-7/30 pm
So some natural light and some mixed, so setting PRE WB,my friend wants some shots showing people dancing and the size of the Hall,so no flash,was going to use ISO 400 to 600,and tripod of course.10-20 sigma.
The question is this, as I am going on my hols a couple of days later,I will have no time for post processing.

So not having used in camera sharpening what do you sud jest
Auto or a setting around 5 (0 to 9)
Any suggestions welcome.

I'd suggest shooting in RAW and use the Unsharp mask facility in Capture NX before converting to JPEG.

Thanks for reply spcomp, but I will have no time for PP and want to give the card to him for him to get them printed,
I'll just shove the in camera sharpening half way and cross my fingers.
