Each of the panoramic photographs presented here started out as a series of adjacent and overlapping individual panels. Each panorama comprises anywhere from 2 up to 24 such original photos. They were stitched together into a single continuous view using one of two software tools, the specifics of which I'll get to in a moment. Although the resulting panel alignment is not as seamless as that produced by a true swinging panoramic camera, each program's price ($130) is considerably more attractive than that of the least expensive digital panoramic camera I have been able to find ($13,600). Sometimes I match densities using Photoshop before stitching, and sometimes I have to send the stitched result back to Photoshop if I got too wild with vertical error when capturing the original scene. The tool I now favor is called Panorama Factory, but I have also used PanaVue ImageAssembler. Both tools have undergone vast improvements in the past couple of years, and now attempt to allow for the frame-to-frame variations inherent with a hand-held series. For both programs, I only use the more labor-intensive manual stitching modes because of the resulting superior pixel alignment. I currently favor Panorama Factory because of its simpler human interface, its fine-tuning algorithm, and its quicker method of alignment flag placement. Each program is undergoing continuous improvement, so watch this space for any leapfrogging news. Some hints for more successful panorama creation: It is crucial that all the original photos are taken from the same point in space. Otherwise near objects line up differently against distant objects, and it is mathematically impossible to align the images later. A tripod really helps here, with the side benefits of sharper original panels and of lowering the panel-to-panel vertical misalignment or rotatation, which neither program is very good at correcting. It is also better to disable your camera's automatic exposure and color balance, and manually adjust the exact same settings for each original photgraph for better control of the color matching when the panorama is blended. Both tools can match exposures after the fact, but the results have been less than satisfactory for me. Although the tools can align adjacent panels with as little as 10% or as much as 90% overlap, I have found that a 50% overlap between panels works well for me. And finally, if some object in your scene is in motion, try to capture it in the center of one of the panels, and then avoid capturing it in adjacent panels. Obviously, this requires that you end up with less than 50% overlap. To maximize the overlap, a speedy camera is helpful. |
