After learning about PixelTools (thanks Darren) and then eyeing the film lab collection for a while I finally had to get it and what a set of Powergrades.
As non-destructive, editable grades you can apply and tweak to suit your needs. The best bit is to take a look at how they built it all up to understand more about what goes into emulating a film look.
The utilities are great as they give you specific elements you can drop into your own work when you only need a bit of something rather than the entire package.
