Film images are relatively easy to store. One limitation of traditional film images is that they are not available immediately after capture. Digital Cameras Digital cameras let you preview images as soon as they are captured. You therefore have immediate feedback about whether you have captured an adequate image. Digital camera technology is improving dramatically, so you can now capture electronic images of unprecedented resolution and dynamic range.
Digital cameras are ideal tools for forensic lab applications.
If you have a piece of evidence you need to document to support court testimony, for example, or if you have a latent print you wish to prepare for submission to an AFIS search, you can use a digital camera to capture a series of high-quality images. You can then preview the images to see if the lighting and focus is correct, and if the artifact you meant to show is well displayed. Digital cameras allow you to save on production costs because you don't pay for repetitve images. You also eliminate any uncertainty about whether you have a clear image with sufficient detail to accomplish your objectives. Digital imaging technology allows law enforcement agents to analyze photographs in real time using computers.
