How I Document Degrading Multimedia Exhibitions
Most people think the hard part of exhibition documentation is taking good photos. It isn't. The hard part is dealing with something like Exhibit Of Sorrows, an installation that was deliberately designed to decay over time and then trying to create a permanent record of it. The work exists in a state of controlled deterioration. Your documentation has to capture what is there without pretending the deterioration hasn't happened. I spent three weeks working with a similar project last year. The piece used expired photographic chemicals on fiber-based prints, analog video stored on degrading magnetic tape, and site-specific architectural elements that couldn't be moved. Each component had its own degradation rate. The prints were fading at different speeds depending on the substrate. The video had tracking errors that got worse every time you played the tape. The architectural elements were gone, dismantled by the original venue. You can't digitize something that doesn't exist anymore, but you can document the gap.
Getting the Metadata Right Before You Start Shooting
Before I pick up a camera, I need a complete inventory and condition report. This sounds obvious but people skip it. A photograph without proper provenance metadata is just a picture. I've seen entire exhibition archives become useless because someone photographed objects without recording where they came from, how they were stored, or what condition they were in at the time of capture. For each item I document, I record: the acquisition date, current physical condition, environmental history, chain of custody, and how it relates to other items in the exhibition. If the piece is multimedia or interactive, I also document the original viewing experience—the lighting, the sound, the sequence, the duration. None of this is negotiable. Without it, you've built a database of images with no way to verify what they actually represent.
The Technical Process for Different Media Types
Digital photography requires a completely different approach than scanning or video capture. Each method has specific limitations you need to understand before you start. I'll walk through what I actually do rather than what a textbook would tell you to do. For fiber-based photographs, I use a copier arm with a macro lens and shoot at f/11 for maximum depth of field. Natural light diffused through a silk panel works better than studio strobes because it reveals surface texture and any fading patterns without creating harsh shadows. I always include a color calibration target in the frame. The target gets cropped out in post-processing, but the color accuracy it provides is essential for archival purposes. Here's something most documentation guides don't mention: you should photograph the same object under different lighting conditions. A raking light at a low angle reveals surface texture, craquelure, and previous restoration work that flat lighting completely hides. I take one set of images under diffuse light for color accuracy and another under directional light for surface analysis. Both files go into the archive. They serve different purposes.
Get the Full Details
For prints with active degradation, like the ones in this type of multimedia installation, I photograph them at their current state. I don't try to digitally restore the colors or remove stains. The degradation IS the record. Restoring the image digitally creates a false document. What matters is capturing exactly what is visible right now, before the next batch of fading happens.
Analog Video Tapes
Video preservation is where most people fail. Playing a deteriorating tape repeatedly accelerates the damage. I use a professional deck with a timebase corrector and capture frame by frame, not continuously. Each frame gets saved as an uncompressed TIFF sequence. This takes longer but it's the only way to catch transient errors that disappear between frames. The tracking errors in degraded tapes are permanent. You can't fix them in post-processing without introducing artifacts that misrepresent the original image. My approach is to document the errors themselves. The visual noise becomes part of the archival record. Future researchers need to know what the tape looked like during playback, including the degradation patterns. I also maintain a separate log file for each tape session. Every error, every artifact, every moment of signal loss gets timestamped and described. This log becomes as valuable as the captured footage because it explains the condition of the source material. A clean capture of a degraded tape without documentation is misleading. It suggests the image was always that way.
What Most People Get Wrong
The biggest mistake I see is treating preservation as a purely technical problem. It isn't. It's about understanding what the artist intended and how the materials were meant to change over time. I documented a multimedia exhibition once where the curator kept asking me to "fix" the color in degraded photographs. I refused. The color shift was part of the work's meaning. Preserving the degradation accurately served the artist's intent better than artificially restoring the original colors ever would. Another common error is relying on automated metadata extraction tools. They miss things. I've seen databases where the creator field was populated with the wrong name because the tool extracted text from a label that listed the donor, not the artist. Or where the date field was filled with a serial number instead of a year. Manual verification of all extracted metadata is non-negotiable. Take twenty minutes to double-check every field. It saves months of correction work later.
File Formats and Storage
For images, I use uncompressed TIFF for master files and JPEG2000 for access copies. The TIFF files go into a cloud-based archive with redundant storage. The access copies live on a separate server so researchers can view them without touching the masters. For video, I store the frame-by-frame TIFF sequences as individual files organized by tape and timecode. This is bulky but it's the only format I trust for long-term preservation. MP4 and other compressed video formats become unreadable within decades. TIFF sequences don't have that problem. The real cost isn't the storage. It's the maintenance. File formats become obsolete. Systems need periodic migration. I budget roughly fifteen percent of the initial documentation cost per year for ongoing preservation work. This covers integrity checks, format migrations, and hardware replacements. If you skip this budget, you're not preserving anything. You're just moving data from one dying drive to another.
When Documentation Fails Completely
Sometimes you can't save the record. I worked on a project where the original installation required a specific architectural space that was demolished before documentation could begin. The multimedia elements were tied to the building's acoustics and lighting. Without those conditions, any reconstruction would be a guess. I documented what remained: photographs of the space before demolition, interviews with people who experienced the original installation, and any surviving physical components. The result was incomplete but honest. It's better to document the gap than to pretend it doesn't exist. This is the limitation nobody talks about. Not everything can be preserved. Some works are designed to disappear. The documentation process has to acknowledge that failure is sometimes the only accurate record. You capture what you can. You note what you can't. You move on.
