25 Questions

1. What is the difference between a Digital Image and Digital Evidence?

Digital Image = a representation of a physical object. (The physical object is the evidence) Digital Evidence = stuff such as Child Porn in which the data is the evidence, OR if an item of evidence cannot be recovered, such as bloody fingerprint on a concrete wall, the image itself then becomes the evidence.The camera automatically creates a reciprocal exposure. SO - if the initial shutter speed is 1/60th and is changed to 1/125th, this WILL NOT result in a -1 exposure. Same thing when the f/stop is changed, a reciprocal exposure will be created. This is NOT how you bracket in auto exposure mode.In focus.History Log: maintains a list of the processes performed for ALL editing sessions. History Window: Displays only the steps for the current image processing session.
