An overhead photomosaic

A multi-image Photomosaic Panorama

collage-1 Yesterday I was walking under an avenue of deciduous trees that made a wonderfully patterned canopy, but even a wide angle lens would not adequately capture the effect, so I turned to the multi-image panorama solution. Be warned however not all multi-image photomosaics will automatically turn out for the best, Autostitch and similar program are written with the assumption that they will have a conventional landscape view, with a horizontal horizon and vertical trees or building as a reference, The tops and bottom of the image may need to be stretched to maintain this. When you don't have strong horizontal or vertical lines the stretching can be unpredictable, so you may need to tinker with your software's setting.
