Hi All,

I joined this community and bought my first DSLR at the end of the year, then, without giving myself much time to learn, I was off travelling for some 8 weeks.
I'm looking though some of my photos, and I'm seeing an issue I cannot ignore... manly with pictures of big buildings in big cities:

I have some buildings appearing to lean at ridiculous angles.

Having investigated, I understand that this is caused by lens distortion, and is most exaggerated using a zome lens at it's shortest. Please see the example below.
I have been saving photos in raw format (.nef) and, as yet, I haven't used any PP software other than Nikon ViewNX2 which came with my camera.

What is the best way for me to deal with this distortion?
Thanks for any advice.
Matt.
