I'm using LuaLaTeX to write my thesis and I've been learning about typography thanks to Robert Bringhurst's "The elements of typographic style". Problem is I can't replicate the letterspacing used in titles sectioning, so do you know how I can achieve that? (I tried with microtype package with no success at all).
My cls is inspired heavily by Evind Uggedal's thesis (which at the same time he is inspired by Robert Bringhurst's book) but he is using pdflatex instead of LuaLaTeX.
Here is Eivind Uggedal's cls: https://bitbucket.org/uggedal/thesis/src/5017b3e8bdb8/src/uiothesis.cls
Here you have an screenshot:
As @rdhs has pointed in the comment below you can use the two options he wrote. In my case I prefer the first one because I don't have to import another package, so if you are going to use it make sure you update your microtype package to the last beta version (visit this site if you need more info http://latex-alive.tumblr.com/post/1303450459).
tlmgr --repository http://tlcontrib.metatex.org/2011 update microtype
Here is the final result:
As @NVaughan said in the comment below, if you're using TexLive 2012 you should type:
tlmgr --repository http://tlcontrib.metatex.org/2012 update microtype
