Imaging Engineering & Color Science

I build C++20, Python, and Swift/Metal tools for camera image quality, color science, and HDR/SDR research. My work combines sensor-level analysis, numerical methods, and hands-on color measurement with professional studio experience as a Photographic Assistant and Digital Capture Technician.

Selected work

Stimulus editor showing two gray disks on a black field, with a layer inspector reporting per-layer luminance in cd/m², the size mode, and the display's extended-range context.

HDR psychophysics platform

A macOS platform for authoring and running HDR and SDR psychophysics studies, built to keep requested stimulus state, realized renderer state, and measured output as three separate records.

CAM16 and Hellwig–Fairchild calculator

Enter an XYZ value and viewing conditions, then compare what CAM16 and the 2022 proposal predict. The model runs in the browser, from the same tested source as the standalone tool.

Line chart comparing Nikon D800 and D810 MTF50 across aperture, with center-to-corner margin bars.

SFR/MTF across aperture and field

Across 299 accepted regions, a center-only score missed important field behavior in the D800 series.

Display-P3 to sRGB gamut mapping

Local MINDE lowered mean CIEDE2000 to 2.323, but no method won across average error, worst case, and hue behavior.

Dot plot comparing ISO-style color-fidelity scores for five cameras across three chart sets.

Spectral sensitivity and camera color fidelity

Four cameras closed against paired chart captures at 9.5–13.8% RMS per channel; the unpaired fifth remained unscored.

Heatmaps of center-normalized green response and red-to-green chromatic response, with a screening summary.

CFA flat-field response

Only 3 of 52 sphere frames retained headroom; equal-radius corners still spread by 16.1–20.0%.

From photography to imaging systems

My B.F.A. in Professional Photographic Illustration included the Advertising Photography option and a minor in Applied Imaging Systems. That background joined lighting, capture, and visual judgment with the technical questions that now drive my camera, color, and display work.

Imaging and color measurement

Eight public investigations connect camera sharpness, sensor-level uniformity, color characterization, spectral analysis, instrument measurement, and color-management algorithms. The studies lead with what was found; reports, formulas, aggregate data, and tested C++20 excerpts remain available one level deeper.

HDR/SDR psychophysics research platform

I built an end-to-end Swift/Metal macOS research application for study authoring, controlled execution, response and session records, HDR presentation state, measurement context, psychometric analysis, and structured export as part of my M.S. thesis under Dr. Mark D. Fairchild.

See how the platform separates requested state from measured output.

Camera and photographic practice

My experience includes color-managed capture and output, digital and film systems, studio lighting, video, camera and image-quality evaluation, and color measurement. In an advertising studio I supported professional capture, lighting, and color-managed workflows. At RIT I spent four continuous years as a Photographic Equipment Student Manager, supporting a 3,000+ item facility and supervising 35+ student employees.

Current focus

Camera measurement, color-management algorithms, spectral analysis, HDR/SDR experimentation, display-pipeline validation, and modern C++.
