Lens distortion correction was done per this specific lens through CS5 plugin software. As far as trying to correct the vertical lines I went as far as I felt comfortable where the image started to become unnatural with more perspective correction which was maxed out. Even more cropping in the corners would have been needed where I did not want to loose any more of the original image. I restretched the image to compensate for the compression but the fireworks where being shot so high in the sky on some of the shots and the explosions where so big that I had to aim my camera up to even greater angles which increased distortion even more. I made a judgement call to do this as I was maxed out on the mm and no room to move. On the full res image viewed on a large screen you can see the lens struggling in certain areas for sharpness. When you drop its size down for use on the web these details get harder to notice. If I where to print this to a nice size I would be able to see the deficiencies. I bet the 14-24 ED Nikon lens would have really helped this image in the full frame sharpness department.





Here is one where I did not have to adjust the camera angle to capture the full view so less perspective correction needed.
