Frequently assess the condition of your artworks and periodically update condition reports. Frame your photographs properly with UV protection glazing and acid-free mounts and use passe-partouts. Look for fading, moisture, cracks, brittle or possible colour (chemical) changes due to high temperature or humidity variations and keep your lighting levels in the 30-100 lux range. Avoid direct sunlight and don’t overexpose your photographs to artificial light. Use dehumidifiers and a hygrometer to monitor humidity levels. Be savvy with your housekeeping practices in particular with Perspex / Acrylic glazing as it is not scratch resistant and may need appropriate cleaning agents. Store your photographs flat in archival paper or archival sleeves. Rotate your art in and out of storage and periodically change artworks positions within your interior to other light levels and sources.
