2. Technical Methodology & Workflow

My workflow is distinct in its reliance on Computational Photography and Spectrally Accurate Imaging. I do not simply "capture" an image; I construct a digital record based on measurable data points.

2.1 The Hardware Ecosystem

Building a trustworthy digital archive requires absolute precision at every stage of imaging. My equipment and workflow follow international museum standards to ensure lasting authenticity.

Sensor: Hasselblad 907X & CFV II 50C and 100c (50-100 Megapixels).
‍
‍Why this matters: Unlike 35mm DSLRs (12-14 bit), the Hasselblad captures 16-bit color depth, providing 281 trillion colors.
This ensures smooth tonal transitions in gradients and recovery of details in deep shadows (15 stops of dynamic range), essential for dark oil paintings or carbon-based inks.

‍Optics: Hasselblad HC/HCD Macro Lenses.
‍
Why this matters: These lenses are shutter-integrated, allowing flash sync at all speeds to eliminate ambient light contamination, and are corrected for flat-field reproduction (zero distortion at the edges).

Illumination: Broncolor LED F160 / Siros S.
‍
‍Why this matters: I utilize lighting with a CRI (Color Rendering Index) of 98.6+. Standard studio lights (CRI 90-95) fail to render certain reds and blues accurately. my equipment guarantees spectral fidelity, ensuring the digital file matches the physical artifact chemically.

Verification: Eizo ColorEdge Monitors & X-Rite Calibration.
‍
‍Why this matters: My monitors are hardware-calibrated daily. What we see on screen is mathematically aligned with the raw data.

Flat Light Painting Photography

Application: Paintings, drawings, prints, photographs, manuscripts, and artworks with glossy or textured surfaces.

‍Methodology: The artwork is photographed using a specialized, symmetrical lighting setup combined with diffusion and polarization techniques. This configuration eliminates reflections, glare, and shadows while producing perfectly even, flat illumination. High-resolution, color-calibrated capture ensures maximum detail and accuracy.

‍Benefit: Delivers a true, distortion-free digital representation of the artwork, preserving fine detail, texture, and color fidelity for conservation, publication, and long-term archival use

Quality Control (QC) & Standards

I operate under a strict Trust but Verify protocol.

Scene Calibration:
‍
‍LCC (Lens Cast Calibration): Every lens/aperture combination is profiled to mathematically remove light fall-off (vignetting) and sensor dust.
Geometric Alignment: Laser leveling ensures the sensor plane is perfectly parallel to the subject to prevent keystoning.

Colorimetric Verification:
‍
Every session includes the capture of an ISA GoldenThread or X-Rite Digital SG target.
Targets are analyzed to ensure a DeltaE 2000 (ΔE00) of < 3.0, strictly adhering to FADGI 4-Star requirements.

Data Integrity:
‍
Files are shot tethered to a workstation.Checksums (MD5) are generated upon ingestion to ensure no data corruption occurs during transfer or storage.

Scope of Deliverables

Advanced imaging projects produce structured digital assets designed for conservation, research, and long-term archiving. Deliverables include high-resolution archival master files, technique-specific outputs (such as multispectral, RTI, focus stacking, gigapixel, or 3D data), and consistent view sets aligned with institutional standards. All files are color-calibrated, quality-checked, and organized using structured naming and folder systems compatible with museum databases. Deliveries include preservation masters, access derivatives, and a concise technical summary documenting the applied methodologies.

‍‍Preservation Master (TIFF/RAW): 16-bit, Adobe RGB (1998), Uncompressed. The "raw" digital negative.
‍

Production Master (TIFF): 8-bit, LZW Compressed, Color Graded. Ready for high-end printing.
‍

Access Derivative (JPEG): sRGB, Web-Optimized, Metadata Embedded (Title, Copyright, Accession).
‍

Technical Data (If applicable): RTI viewable files (.ptm/.xmp), UV/IR comparison stacks, or 3D Object files (.obj).
‍

Strategic Benefits to the Museum

investing in this level of digitization provides returns in three specific areas:

Preservation & Risk Mitigation
‍
‍Digital Substitution: By creating a "Digital Twin" with forensic accuracy, the need for physical retrieval of the object is reduced by up to 80%. Researchers can answer questions regarding condition, text, and technique using the digital file.
‍Condition Reporting: The Gigapixel and UV/IR files serve as a "state of record." Future damage or degradation can be measured against this baseline with pixel-level precision.
‍

Academic & Curatorial Authority
‍
New Discoveries: Computational imaging (RTI/IR) frequently reveals details invisible to the naked eye—faded signatures, erased text, or tooling marks—generating new scholarship and publishing opportunities for the Museum.
‍Global Access: Publishing FADGI-compliant images establishes the Museum as a leader in open access, attracting international attention and scholarly collaboration.
‍

Revenue & Sustainability
‍
Licensing: 100MP+ Hasselblad files allow for premium licensing (billboards, high-end art books) that standard DSLR captures cannot support.
‍Print-on-Demand: Gigapixel resolution allows for the creation of "life-size" or "macro-detail" prints for the museum shop, creating a new revenue stream.
‍

Terms & Requirements

Museum Responsibilities: Provision of a secure, climate-controlled working footprint (approx. 3x3 meters); presence of an art handler/registrar for all object movement.
‍

Insurance: Consultant carries full Professional Liability and Equipment Insurance. Museum retains insurance on all artifacts.
‍

Copyright: All intellectual property and copyright of the digital assets are assigned 100% to the Museum upon delivery. The Consultant retains only a limited license for portfolio use (accreditation required).
