A bit of an experiment I did earlier this summer. 15 images pano (3*5). 9 second exposure at f/7 per frame with a 50mm lens. I added some notes with directions.
Check out the high res.
Took me quite a while to stitch together. My computer was suffering. The image is unaltered in terms of saturation. I tried to keep it faithful to the actual scene.
Overall the stiching seems to have come out quite ok. There is only slight banding in the sky on the left which seems to be the result of the poor RAW converter in the stitching application.
