There is another issue, the quality of the digital capture. Kodachrome has a unique look that differs vastly from Fujichrome, and many PI's use a film based on its particular qualities to improperly prejudice results in client's favor. You can always rent, but you probable would not have the software nor know how to use either properly. One clear fact remains, the quality of the files captured with the right digital camera system far surpasses that of film, while providing significant advantages in the creation of images. Analyze the technology for a moment to compare cameras and identify your budget.
Resolution is a crucial specification when evaluating a digital camera.
The number of pixels a camera can create greatly affects the quality of the printed output. The more pixels a camera provides, the larger the file that can be output with acceptable results. Most desktop models produce at least a 640x480 pixel image, up to about 1,280x1,024. The number of pixels you end up with is a most important factor in the purchase of a digital camera. Some cameras use less than the full resolution of the CCD to create smaller files.
