This Saturday, I did an early morning shoot at Huntley Meadows in Alexandria. This image is from 20 images, processed in ASP3, output as ProPhotoRGB TIF and stitched in Hugin. Even after dropping the resolution quite a bit, it's too large to upload. When I print it, it'll be 16 inches by over 6 feet.
Hugin is a tremendously capable tool, and I especially appreciated that it maintained the color space in ProPhotoRGB..
