Use a supported overhead camera rig as your default. A rigid copy stand, non-contact cradle, diffuse low-heat lighting, manual focus and exposure, and a gray or color reference let you adapt to paintings, bound pieces, textured surfaces and oversized work without forcing the object onto glass. Use a flatbed or specialized scanner only when the artwork is flat, stable, correctly sized and can be captured without pressure or damaging heat.
The capture device is only one part of an archive. Preserve the camera-original or scanner-original file in a lossless format, keep edited files as derivatives, and attach descriptive and technical metadata. If an item is loose, flaking, brittle, stuck, severely curled or structurally compromised, stop and involve a conservator-aware digitization service.
What makes a tool suitable for fragile artwork?
Choose equipment by the risk it creates for the object, not by resolution alone. A high-resolution image is not an archival capture if the artwork was pressed, overheated, forced flat or inaccurately colored.
- Non-contact support: the object rests on a cradle, board or other support rather than being pulled through a feeder or pressed under a lid.
- Geometry tolerance: the setup accommodates bindings, relief, texture, curled edges and large dimensions.
- Controlled illumination: light is even and glare is managed, with heat kept as low as practical.
- Color control: a gray card or color target is captured under the same lighting as the artwork.
- Repeatability: camera position, lighting, focus and processing can be reproduced for a series.
- Preservation workflow: originals, derivatives, metadata and integrity records remain distinguishable.
The Library of Congress says form-feed equipment is unacceptable for fragile, high-value, fine-art or archival materials and advises against placing glass or Plexiglas on artwork. U.S. National Archives guidance likewise warns against forcing bindings open. These are handling constraints, not optional quality settings.

Why an overhead camera rig is usually the safest default
Build a rigid, parallel setup
Mount the camera on a copy stand so the sensor remains parallel to the artwork. A rigid stand prevents perspective changes between frames and avoids leaning over or touching the object. Use a cradle for bound material; never flatten a binding simply to fit a scanner or to make a page look square.
Support without contact pressure
Support the work on a clean, stable surface. For a book or portfolio, set the opening angle that the binding can tolerate and capture each side without forcing it farther open. For raised or textured artwork, allow the surface to remain in its natural position rather than clamping it.
Use diffuse, even, low-heat light
Place diffuse lights symmetrically to reduce gradients and glare. Keep the lamps far enough away and cool enough that the object does not warm. For glossy paint, adjust the light and camera angles rather than wiping, pressing or covering the surface. A setup reference frame should include the gray card or color target before the artwork sequence begins.

One-click scans. No signup required.
Set focus and exposure manually
Autofocus and autoexposure can change between frames when a border, dark pigment or white paper enters the scene. Establish focus on the artwork plane, lock it, and use manual exposure so a series remains consistent. Capture RAW when the camera workflow supports it; retain that file as the camera original.
When a scanner is appropriate
A flatbed or specialized scanner can be efficient for a flat, stable original that fits entirely on the bed and can be captured without pressure. The Library of Congress recommends equipment sized to the object and controls that limit light and heat. Check the lid, platen and transport path before placing any artwork on the device.

Pre-flight checks
- Confirm the object is flat enough to rest without bending, crushing or catching an edge.
- Confirm the active area is larger than the artwork; do not trim, fold or force it to fit.
- Determine whether the lid applies pressure. If it does, do not use it for fragile work.
- Check the scanner’s illumination and heat behavior and avoid a prolonged sequence if the object warms.
- Make a short test with a safe surrogate before the original.
Automatic-feed scanners are a different category. National Archives guidance identifies them as unsuitable for fragile, weak, bent or valuable papers because rollers and the feed path impose handling forces.
Color accuracy: target the capture, not just the software
Make a reference capture
Photograph a neutral gray card or color checker under the same lights, camera position and exposure used for the artwork. Keep the target in a setup frame rather than placing it on a delicate painted surface. Use the reference to establish white balance and, where supported, a consistent camera profile.

Choosing a target
The X-Rite ColorChecker Passport Photo 2 (model MSCCPP-B) is documented as containing gray-balance, white-balance, 24-patch Classic and enhancement targets, with software for custom DNG and ICC camera profiles. X-Rite marks that model out of production and directs users to Calibrite for an upgrade, so verify the current successor before purchasing. Do not assume an old listing is still the supported model.
Keep a consistent correction policy
- Apply the same white-balance and camera-profile method to the complete capture set.
- Make only restrained post-capture adjustments needed to represent the object and correct the capture.
- Record any crop, rotation, tonal adjustment, stitching or retouching in the processing history.
- Keep the unmodified original separate from the corrected derivative.
Resolution and file strategy for an archival master
Capture at the highest useful optical resolution your object, lens and lighting can support without introducing blur, glare or unnecessary handling. A larger pixel count does not compensate for movement, poor focus or uneven illumination. Review focus and edge detail at full size before dismantling the setup.

Preserve the original
USGS recommends retaining the original, unmodified scan in an uncompressed or losslessly compressed format such as TIFF or PDF, then using a copy for cleanup and distribution. For camera work, retain the original RAW when available and create a lossless master after controlled processing. Do not overwrite either file with a web-sized JPEG.

| File | Purpose | Typical handling |
|---|---|---|
| Camera or scanner original | Evidence of the capture | Read-only storage; never overwrite |
| Lossless preservation master | Stable archival representation | TIFF or another lossless format; retain full captured detail |
| Working derivative | Color correction, crop, stitching or cleanup | Use a copy and record every material operation |
| Access derivative | Web, catalog or sharing | Resize or compress only after the master is secured |
Keep checksums or other integrity records where your storage system supports them, and maintain redundant backups. A backup is useful only if you can identify which file is the master and verify that it has not changed.
Metadata is part of image quality
NARA states that an image is not high quality unless metadata is associated with it. Put the descriptive record beside the files or in a collection system, and retain technical data with the master.
Record for every object or sequence
- Object identifier, title, creator and rights information when known
- Capture date and operator
- Camera or scanner model, lens, focal length and working distance when available
- Lighting type and arrangement
- Color target or gray-card identification, white balance and color profile
- Orientation, scale information and whether the image is a recto, verso or detail
- Software and processing history, including crop, stitching and tonal changes
- File format, dimensions, storage location and checksum or integrity record
- Condition notes and any handling restrictions
Use a stable identifier that connects the object, the original, the master and every derivative. This prevents a beautifully captured file from becoming separated from the artwork’s identity or provenance.
Step-by-step workflow
- Assess condition. Look for loose or flaking media, brittle supports, stuck pages, severe curls and structural weakness. Stop and seek conservation advice when the item cannot be supported safely.
- Choose the capture path. Select an overhead camera for irregular, bound, textured or oversized work. Select a scanner only if the object is flat, stable, correctly sized and free of pressure risk.
- Prepare the workspace. Clear the surface, wash and dry hands as appropriate to your institution’s policy, stabilize the stand or scanner and remove anything that could touch the artwork.
- Set support and geometry. Use a cradle for bindings, keep the camera parallel, and leave enough clearance for raised or curled areas.
- Set lighting. Arrange diffuse, even, low-heat lights and inspect the live view for glare, reflections and gradients.
- Capture the reference. Photograph the gray card or color target under the final lighting.
- Lock camera controls. Set manual focus and exposure; keep the same settings for the sequence unless the artwork requires a documented change.
- Capture the original. Use RAW when available, or the scanner’s least-processed lossless option. Include an identifier and sequence record.
- Inspect before moving the object. Check focus, edges, shadows, glare, clipped highlights and complete coverage at full size.
- Create the preservation master. Process a copy, apply the documented profile and restrained corrections, and save a lossless master.
- Create derivatives and metadata. Export access files only after the master is safe; attach descriptive and technical metadata and record processing.
- Verify storage. Write checksums or integrity records where available, make redundant backups and test that files can be opened from the backup.
Common failures and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| One edge is soft or the artwork looks trapezoidal | Camera is not parallel or the object is not evenly supported | Re-square the copy stand, stabilize the support and refocus on the artwork plane. |
| Color changes between frames | Autoexposure, autofocus or changing light | Lock focus and exposure, keep lighting fixed and apply one documented profile. |
| White areas lose detail | Highlights clipped during capture | Reduce exposure before repeating the frame; do not try to reconstruct missing detail in editing. |
| Glossy paint shows bright streaks | Specular reflection from the light angle | Move or diffuse the lights and adjust the camera angle without touching the surface. |
| Pages or boards bow at the center | Binding or support was forced flat | Use a cradle and capture at a safe opening angle; never press the object under glass. |
| The scanner catches or bends the artwork | Object is too fragile, large or thick for the transport path | Stop immediately, remove it without pulling, and switch to supported overhead capture or professional handling. |
| The archive contains only edited JPEGs | Originals were overwritten or discarded | Restore the original/RAW or scanner-original retention policy and create derivatives from a protected master. |
| A file looks correct but cannot be identified later | Metadata was omitted or detached | Use a stable object identifier and attach the capture, technical and processing records before distribution. |
Performance, reliability and cost decisions
Throughput depends on handling time as much as on device speed. A scanner may be faster for a stable stack of compatible flat originals, while a camera rig avoids repeated platen contact and adapts to objects that cannot be flattened. For fragile work, the safer setup generally wins even when each frame takes longer.

Budget for the complete system: a rigid stand, suitable support or cradle, diffuse low-heat lights, a camera and lens, a color reference, storage and redundant backup. Consumables and labor for inspection, metadata and quality control are part of the archive cost. A cheap device that causes a single damaged original is not a low-cost workflow.
Repeatability improves reliability. Mark stand positions, keep a setup sheet, use the same reference capture method and review a sample from every batch. FADGI’s Third Edition was published in 2023, with the FADGI page last updated 2024-02-27; use current institutional requirements when your project has a formal compliance target. NARA’s cited technical guideline dates to June 2004, so treat it as foundational guidance and verify any newer requirements from your institution.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When to use a professional service
Refer the work to a conservator-aware provider when it is brittle, flaking, stuck, severely curled or otherwise unsafe to open or support. Ask how the provider handles stabilization, lighting and heat, originals and derivatives, color references, metadata, file formats, backups and delivery of the unmodified production master. The service should be able to explain what will happen if the object cannot be safely opened or captured.

Frequently Asked Questions
Should I flatten a curled artwork before photographing it?
No. Do not force a curl flat. Support the object in its safe position and obtain conservation advice if the shape prevents a complete, non-contact capture.
Can a web screenshot replace a preservation image of the artwork?
No. A screenshot documents an online page. The preservation image must come from a controlled camera or scanner workflow that captures the physical object.
What should I do if the target is unavailable?
Use a clean neutral gray or white-balance reference and document exactly what was used. Verify the current supported color-target model before buying a discontinued product.
How do I prove that an archived file has not changed?
Store a checksum or other integrity record with the master and verify it after copying or restoring from backup.
Is a higher pixel count always better?
No. Focus, even illumination, accurate color and safe handling matter first; extra pixels cannot restore clipped detail or compensate for motion blur.
