Here's a few examples of HDR images I've produced from my visit the Naval Museum. I rented a Canon 16-35mm F2.8 'L' lens for the trip.
I've been using two different HDR programs. Picturenaut and Cinephoto.
I took this sequence of photos in the under Lake Michigan exhibit.
The Composite HDR image.
Original exposure, 20 seconds!
