Correcting Barrel Distortion
Because my 17-85mm is not particularly great at the wide end, I will usually have to deal with barrel distortion. My research indicates that there’s only one good and common way to correct barrel distortion: using the open source Panorama Tools. Plugins that employ Panorama Tools are available for Photoshop and GIMP. There’s also a standalone program that uses Panorama Tools — it’s called hugins (don’t ask me where the name came from).
Panorama Tools is extremely user-unfriendly. (This reminds me of my experience with the open source FFmpeg utility for performing video format conversions. Why are such common power tools such frakking bitches to use???) Open source developers are archetypical geeks who have zero understanding or concern for user-friendliness. A pox on them.
Anyway, I have my work cut out for me to learn how to correct for barrel distortions. (Don’t think the problem goes away if I buy a $2,800 EF 14mm f/2.8 L lens.)
