There is an auto enhance feature in adjustments but you're really going to have to supply more information as to what it is you are looking to do and what you mean by 'touch up a photo'.

Have you read the chapter of the User Manual on making Adjustments? Aperture's User Manual is good, and serves well as a first point of reference.
