PanoTool turns an iPhone or iPod touch into an inclinometer for taking panoramas with SLR and compact digital cameras. It provides audio feedback for pitch settings for up to 4 rows whilst at the same guarding against sideways camera roll.
Accurate pitch positioning makes it possible to make handheld 360กใ x 180กใ panoramas with suitable wide angle lenses.
With SLR cameras in portrait position the iPhone is held against the flat bottom of the camera preferably using velcro to prevent slipping and with compact cameras usually only a couple of rubber bands and a small piece of packing are necessary.
