Mike,

My thought is that while Sandy is asking in reference to InDesign it would be good in this forum as afaik all the Adobe CS apps share the same 'type engine,' and all offer the choice of metic or optical. I think this would be an interesting topic of Typography for most Adobe applications - but then the long books specification would prob put it back into InDesign, oh the decisions...

Sandy,

I think metric uses the font's built in kerning information, that is the settings the font designer made the font with and optical uses an algorythm so that the software creates what it 'thinks' is the best kerning. Guess it depends on the font and how well it has been made as to which method works best. Don't tke this as authoritive information though and anyone who knows better please correct me.

Cheers,

Sam.
