The main point I want to stress is that if you are starting out in real estate photography and trying to decide what photo editing software is best for you, Lightroom 2 (or Aperture 2.1) and PTlens is all you need to do create great interior photos. Here's why:
Here are some of the things I like about using PTlens as an external editor from Lightroom or Aperture:
What about Photoshop Elements (PSE) and Photoshop CS3 (PSCS3)? I get asked this all the time and here's what I tell people: Photoshop evolved over the last 10 years or so as a photo-editor that does everything for everybody whereas Lightroom and Aperture were specifically designed in the last year or two just for photographers. They are really good at helping you catalogue, sort, select and adjust images from a photo-shoot. Yea, there are some things you may eventually want to do that you will need one of the Photoshops for like sky or window replacement, removing cars from driveways or using the photomerge feature to create panoramas but these things are in the advanced 5% of real estate photography post processing.
