Image “Gamuts” and Accuracy
It is an ubiquitous standard that forensic images be accurate, yet there is simply no such thing as an accurate photograph. The actual question should be whether or not the natural inaccuracies of a visual artifact are germane to an argument.
Temporal Video Compression: Why Video in Litigation Can Be Perilous
Like .jpg (Joint Photographic Experts Group) compression, video compression is mathematically very complex.
Quantization: A Fundamental Digital Concept
Digital Sampling occurs at regular intervals in an audio stream. The very term "Sampling" implies a resulting less dense or populated data set than the original.
.jpg (“JPEG”) Encoding: The “e” Is For “Experts”
One of the most contentious and misunderstood issues in digital asset management and forensic image virtue is image compression.
Color Management Fundamentals
Devices reproduce color inconsistently. Inaccuracies in color are a forensic liability.
Controlling Color in a Digital Presentation
This demonstration is built in Adobe© Flash©-specifically, in Flash's underlying programming language called ActionScript™.
Elliptical Distortion
Elliptical Distortion is one of the most commonly objected-to phenomena of photography. It's also one of the most ignored aspects of forensic imaging. What an enigma!
Digital Sampling and Quantization: Bit Depth
Bit depth simply refers to the number of bits ("0" and "1" values) used to represent a digital sample, whether referring to audio, still images, or video images.
Audio Sampling: Saving Space at What Cost?
Audio Sampling is one of the most misunderstood aspects of video preparation and security recording.
“Color Temperature” and Color Bias
"Color Temperature" refers to (in photography & videography) the relative balance of Red and Blue in light.
