I enjoy photographing with a Fisheye lens even when entering the American Adventure to listen to the Voices of Liberty.

Many photo editors can “correct” distortions in many lenses including fisheye ones. To test this in my editor of choice, Adobe Lightroom CC, I opened up the Lens Correction brick. After enabling profile corrections, the software found and used the profile for the Sigma 15mm lens I photographed with. Using the profile, Lightroom cropped and rotated the image to straighten the curves created by the fisheye lens. The results you see below.

This is an extreme example but you get the idea. Check your software and see if it has Lens Corrections for any lenses you own.
Certainly, the most important feature, that of the vertical lines of the photo were corrected very well. But it appears to me that the curves of the rotunda, and especially the round curves of the bottom of the dome, are distorted even more by the process. Still minor by comparison to the improvement to the photo by the straight verticals.
Scott replies: Jim, the Fisheye is an extreme case when it comes to fixing distortion. I am going to try a wide-angle on my next trip and see if the software handles it better. Thank you for your comment and observation.
