No direct computer interface. Large emulsion formats provide unequaled resolution. Ample resolution for high magnification, fine structure characterization microscopy. Easy digital conversion for computer input, storage and manipulation. Acceptable sensitivity for low light level applications, marginal sensitivity for high speed applications.
Video has some down sides too.
In the past 5 years, technology applied to video has been modified to provide high quality, high resolution digital images. Relatively high sensitivity and image integration for low light applications such as fluorescence imaging. Digital image cameras have some inherent disadvantages as well. High Resolution 3-CCD imaging with real time image enhancement rivals the image quality of megapixel imagers. Direct digital input without image processing boards.
