I am testing the Perfect Suite 7 for editing. It is a very powerful set of utilities, in a convenient package for round tripping in and out of Lightroom and Aperture. The "unique" thing about Perfect Suite is that it is layers for the rest of us. Photoshop is extremely powerful, as it is pixel level editing. The terminology of Photoshop is that of digits, and not necessarily traditional photography. Some of us out here in the real world have trouble with the multiple languages required to think Photoshop vs Photography. Perfect Suite is a lot more photo centric, and for me personally easier to grasp. For others who are new to editing maybe it does not matter as much, but it does for me.
I used Suite 6, and I am finding a number of the new Suite 7 tools are easier to access and work with and visualize how they will make their effects. Another thing those on a budget will appreciate is the loyalty program. Perfect Suite updated everything at one time, and you just pay once for all the updated tools for the year. I love Nik, but the incremental update policy means I am still spending more to updating the suite costs more than the initial purchase.
On average I can save a lot of time by using Perfect Suite when I need heavy editing. I can do here in under two minutes what it would take ten or more in Aperture or Lightroom. When editing my big assignments, this is a big deal.
It does have a 30 day free trial, so you can try it out for yourself. Their information on the website explains everything in detail. Perfect Suite 7 Website
