I've been working with a new ebook author the last couple of weeks on a new PFRE ebook on real estate photography post-processing. In the process of comparing all the possible photo-editing software for correcting barrel distortion, converging verticals and horizontal alignment I became aware of an issue that I'd not realized before. It's this:
When you are choosing a wide-angle lens for shooting real estate you better pay attention close attention to which photo-editing software has lens profiles for the lens you are going to buy. If you don't you are liable to find yourself doing a lot of manual distortion correction or switching photo-editing software.
The good news is that PTLens ($25) has profiles for almost every lens on my list and the planet! The developer Tom Niemann has done a fantastic job of making lens profiles available. This video illustrates how easy it is to use. You can use PTLens with Lightroom, Photoshop, Photoshop Elements and Aperture.
For example, if you decide to purchase a Tokina 11-16mm wide-angle lens (according to the poll on my lens page roughly 8% of PFRE readers use this lens) and you expect to use Lightroom or Photoshop CS5 you have a surprise in store for you because they don't have a lens profile for that lens. So you'll either need to use PTLens or DxO Pro to correct lens distortion.
To clarify this issue I'm in the process of adding columns to the lens page that show which of the popular photo-editing software has profile for all the popular wide-angle lenses. I have columns added for Lightroom/ACR but realized while I was writing this I probably need to add a column for DxO Pro too. Frankly, I'm a little surprised that Lightroom/ACR don't support all these lenses. Tom can do it in his basement in Portland so it can't be that hard!
