I’ve been playing with hugin to stitch together the dozens of frames for the Egner Memorial Chapel Stained Glass project. During yesterday lunch I shot some material in the front lawn and turned it into a one of those “little planet” images. Here is a screen capture from the preview dialog. A quick hack….
OK, its terrible, and I’ve quickly learned a lot about what the input images need to be. But still, pretty cool! Next time, it will be AWESOME! I’m already addicted to planetoids.
Update: So after rendering this out, and “correcting” the flag in GIMP, and cloning out the tripod on the lawn and some other noodling, I ended up with this:
I consider this to be pretty respectable, considering the input images were not at all what they needed to be. The above image is construced from 5 concentric rings of images, so as we get further out, the overlap issues an parallax issue get to be severe.
The proper way to shoot this is use a wider lens, as a 15mm ( this was shot at 24mm equiv ) an use a single band, ensuring anything architectural is in full fames.
Even so, the Haas building looks plausible, I salvaged the flag nicely, an at least its not egg shaped.
I got married in The Chapel and so it is somewhat special to me. Its a more modern chapel, built in the 1920′s. The stained glass work in the chapel is rather nice, and I think under appreciated. So during break I have been starting work to create some high resolution panoramas:
The stitched image is about 125 megapixels. The above image, to fit here, is about 5 megapixels, so 5x the resolution you are seeing above. There are various image quality issues, but overall the results are rather nice, and certainly better than anything I could do with a single image from any affordable medium format camera.
With a better lens, like a 400mm APO of some sort, I could easily achieve resolutions perhaps 3x higher, or approximately equivalent to a 150 dpi scan of a 2 story tall object.
