Some of the niftiest software is free. For instance, Hugin, which stitches 360° panoramas together from your pictures. You can then upload the panoramas to 360 Cities for everyone to explore. The basic membership there is also free. The above is the interior of the Wichita cathedral last week.
Although the ideal camera for making panoramas is a full-frame DSLR with a fisheye lens, any camera that isn’t junk will work, possibly even cellphone cameras. Those who travel to picturesque places might want to keep an eye out for possible panoramas.
