I was shooting photos out at Hanging Rock State Park last week, taking a few panoramic series, a handful of HDR sets, long exposures of waterfalls and similar stuff. I also started experimenting with Vertical Panoramas and sets that involved a little more than just the x-axis. One of the sets I took was coming up to the main rock face of Hanging Rock Mountain itself, and for lack of a wide angle lens (or a DSLR that can take a wide angle lens) I took about 40 photos trying to get the whole mountain. Now not wanting to try and stitch it together myself, last night I opened up the files, told photoshop to stitch them together itself (something I don't do on my regular panoramas) and let it do it's thing.
Now I've already discovered that Photoshop CS3's photomerge function doesn't do vertical merges well on it's own, so I finished up the last few chapters of The Anansi Boys checking to make sure it could handle the set before going to bed. It didn't spit up any errors so I let it work into the night, and when I woke up I found it showing off a pretty distorted, and absolutely massive stitched pano, in addition to a few system error messages that were effectively screaming for more RAM.
The 14172 pixel wide by 30634 pixel high image is so big, Photoshop is incapable of saving it as a photoshop file, let alone a jpeg. The only way I could feasible save it was a 3.91GB tiff file, that takes 30 minutes to open on my 1ghz ibook.
I'm in the process of downsizing the file to a more manageable 10000px high, but at the rate photoshop is going it may be a couple hours. Until then, here's a screen shot of the monster photo.
