Since the advent of a high res DSLR, I was able to continue producing images in a panoramic format without carrying an additional bulky panorama camera in the field. Each year, the software utilized for stitching multiple digital images seems to get better, easier, and more sophisticated. The benefit of merging multiple images allows for a much larger file, but file size is not always necessary. I’m going to suggest something that seems to go against the grain of conventional publication/DPI standards for print media.
Dots per inch, or DPI has a direct relationship to viewing distance, and this is sometimes overlooked when evaluating a picture for size-output based solely on DPI. For example, I have four 3.5ft x 10ft panorama images displayed as canvas gallery wrap prints in the Fairbanks International Airport. Two of those were panoramas made from multiple files, and two were cropped from a single 17MP RAW file. When viewed at a distance of 15-20 feet (since they are hung high above the hallway) one can’t tell the difference. All four look quite sharp and clean. If these were viewed from 2 0r 3 feet however, the quality might seem inferior. But then, no one views a 10 ft picture from 3 ft, since you could not even see the whole thing at that distance.
Below is a gallery of panorama images, most of which are digital files stitched together in photoshop, some are film files from the Fuji Panorama 6x17cm camera.
