Who can help me with a good software for defishing/dewiding images ? I need them for my 18-70 nikon lens, that produces altered pictures when used at 18 (curved lines).

Thank you for your help.

Ok, I found that Capture NX already did that... but the problem is that the feature is blocked. Does it works only on fisheye lenses, recognizing them ? Or is there a way to use it also on a standard 18-70mm lenses, when used at its widest angle ?

Defishing with CaptureNX works with RAW/NEF and JPG-files :D
But only when the shot was made with a fisheye.
There is no algorithm in CaptureNX to correcct for geometric distortions of "mainly" straight lenses. You have to do that in PhotoShop or DxO ...

epaperpress http://epaperpress.com/ptlens/ has some software called PTlens that helps correct lens distortions. There's a photoshop plugin and a stand alone version. They also have a trial version that you can try out too. I'm not exactly sure about what file types it works with though.

I also found another program that works very well for shooting architecture, without spending bundle on a tilt/shift lens, but I can't remember the name of it right now. If I find it I will come back and post it.
