PTLens is a PhotoShop plugin that corrects for barrel/pincushion distortion automatically, based on camera profiles.
I submitted some photos to ePaperPress a few days ago, and I’m pleased to say that the Canon PowerShot Pro90IS now has a profile.

Here is a sample before and after image – move your mouse over the image to view the original.
