The length of the shoot is dependent on several factors. The most important variables are resolution, camera, and location.
For example, using a Nikon D1H camera, about 100 low-resolution photos can be shot in 1 minute. The lower the resolution, the faster the process; and similarly, if the photos are taken outside and do not require a flash, the process is also quicker as the photographer does not need to wait for the flash to load.
The number of photographs is dependent on the width of the set. As the number of photos increases, so does the panoramic angle of the picture. As a general rule, at least one photo is needed per one degree.
There is no problem if you wish to stop the process and continue it later, as long as the set and the lighting conditions do not change. If in some photos there were lighting problems or background motion, the user has the opportunity to ignore these photos during the processing stage. If a large number of photos are unusable, then the photo sequence must be reshot.
3D photographs can be taken in black and white.
