Today, electron microscopy (EM) is increasingly confronted by the revolution in image‐processing technology provoked by modern computers. Digital cameras are fast replacing film‐based cameras in EM, as elsewhere, and the procedures for digital image‐archiving, image‐analysis, and image publication are rapidly evolving. To take advantage of these advances, we have chosen for the moment a ‘middle road’, in which film remains our basic recording medium in the electron microscope, but immediately thereafter, all film‐based images are converted to digital files for further analysis and processing. The rationale behind this approach is that film still offers far greater sensitivity and resolution (providing an image equivalent to> 10 000 pixels per inch in a 1‐s exposure), and film is still far easier to organize and archive than digital images of comparable resolution. However, digital manipulation of EM images has become mandatory. Hence, we explain here, in some detail, how we convert from film to digital.
