    NIST is one of the nation’s oldest physical science laboratories, having been established by Congress in 1901. NIST provides expertise in various sciences dedicated to enhancing the United States’ economic competitive posture and integrity.

    OSAC-as part of the USDOC’s Forensic Science Program-is specifically purposed to develop discipline-specific forensic science protocols and standards for NIST.

    Geis provides the OSAC with expertise in ocular physiology and neurology, color science, and applied thermodynamics; sciences related by their common involvement with light energy and manipulation (photonics).

    Geis’ foci include the admissibility and veracity of visual evidence (photography, videography, thermography, etc.) in forensics and litigation, the substandard implementation of imaging and remote sensing within governmental echelons, and human visual performance expectations in various anomalous situations such as traffic accidents and personal injuries.

    Photoshop Histograms are Horribly Underrated and Misunderstood

    Digital imaging histograms (not to be confused with RGB Parades) are a census of pixels whose channel or composite values occupy certain “bins” or discrete values along the x-axis, or abcissa. Easy enough to say, but as the relational axiom goes, “it’s complicated.”

    A Proxy Workflow in Premiere Pro: Hardware, Software…and Practitioner “Configuration!”

    Extreme resolution (e.g. 5.5K+, high bit depth, high frame rate, computationally demanding compression, etc.) can bring even a talented workstation to its knees. However, in our context there is really no such thing as a “fast computer;” a workstation is a combination of hardware, firmware, software, and operator competencies, and any one may drastically depreciate the other/s.

    Channel Operations (“ChOps”) in Photoshop: Automated v. Manual Sky Replacement Example

    Photoshop is a shockingly “deep” application with latent but powerful features for generating selections. There are automated descendants of those features, such as the Edit>Sky Replacement… menu item. Are the automated functionalities competitive with manual ChOps?
