Test Sequence

Tripod Sequence - Gasworks Park

To shoot our final panorama, we went to Gasworks Park. There's a hill at the Southwest end of the park that affords a great view of the park and the surrounding Seattle cityscape, and this is where we decided to take our photos. We also opted to use a DSLR in order to ensure better image quality. Despite it being cold and windy, we weren't the only people up on the hill taking photos, and we actually had to pause a few times to wait for some oblivious tourists to move out of the way.

When stitching the images together, the image solutions we had did not align properly with our solutions nor with the class solutions. To fix this, I adjusted the blending numbers on the blend between images 4 and 5 to be about half way between the numbers of the previous and the next.

Handheld Sequence - Gasworks Park

We used the same camera for the handheld sequence, and took photos from the same spot. This panorama consists of a total of 29 images stitched together. As expected, it was much harder to hold the camera level without the use of a tripod, and the fact that it was a windy day didn't make things any easier.

One thing we didn't consider is that when shooting a panorama, you should pay attention to whether there's any predictable motion in the scene and attempt to follow that motion when you take your photos. We forgot to do this, and there just so happened to be a sailboat moving in the opposite direction -- if you look closely in this image, you'll see it gets multiplied several times in the background.
