The second is to produce a digital file that has higher resolution than that produced by a single frame, often of interest when shooting with a low to moderate resolution digital camera. This technique is equally useful when shooting with 35mm film to create composite frames that are wide enough and large enough to produce extremely large high-quality prints — equivalent to those shot with large format. All it takes is a bit of care when shooting and some work on the computer.
