How to Make a Great Panorama
These are just my basic notes on panorama making. I will add a step-by-step set of instructions with images soon.
Shooting Panoramas
I
quite enjoy panoramic shots. I like the suspense of not knowing
exactly what the end result will be. Some don't work at all while
others that I thought wouldn't work come out amazingly well. Panoramas
look expensive because in the past they could only be shot with a very
expensive lens. I often get comments like "You're very professional, you must have a very expensive lens!"
Fortunately, there's a work-a-round. I shoot multiple exposures
left-to-right overlapping them by about one third or so. (By
remembering to shoot left-to-right, processing the shots is easier since
the images appear in the correct panoramic order in an image browser
application like Adobe Bridge.)
Software
There are many other applications that will stitch panoramas together. I use the inexpensive software Panorama Maker 5 by Arcsoft
to stitch the images together automatically often with some manual
tweaking. Be sure to have plenty of RAM. The more photos you're
stitching, the more RAM you need. I have 8 gigs. After stitching, I
adjust the image using Adobe Camera Raw and then Photoshop. The warp
tool in Photoshop is extremely useful. Panoramas that are not quite
symmetrical or missing a corner can be stretched appropriately using
that tool.
File Size
Also,
because the shots are multiple exposure, the size of the finished image
is impressive as well. (Of course, the images on this blog are greatly
reduced from their original size so they display quickly.) My Canon 7D
is an 18 megapixel camera which captures 5184 x 3456 pixels. But if
I'm taking a half dozen shots, subtract the overlays and the camera is
acting as an image sensor that is approximately 4 times as large! So
even if I owned a really expensive fish-eye lens, I could not get such a
large final image. The number of pixels is not important for
displaying the work on a display, but if the panorama is to be printed
large scale, the large file size is really impressive.
