Copying and scanning are two different methods for digitizing film.

Copying involves projecting the image from the film onto a piece of paper or a specialized copying film, and then photographing it with a digital camera. This method can produce high-quality results, especially when using a high-resolution camera and lens, but it requires specialized equipment and can be time-consuming.

Scanning, on the other hand, involves using a specialized film scanner to convert the film into a digital file. Scanners are designed specifically for film, and can produce high-quality results quickly and easily. They can also correct for many common issues with film, such as color cast and dust.

In general, scanning is the preferred method for digitizing film, especially for large volumes of images. It's faster, more accurate, and more consistent than copying, and it produces high-quality files that can be easily edited and shared digitally.

However, if you need to reproduce an image for print or exhibition, copying may be a better option, as it can produce a higher-quality final product.
