Can anybody help? I am living in a place with extremely high humidity. Normally people do not use air conditioning as it cools down at night. The problem that I have is that ab out 6 months after framing and displaying my photography, the print surface and mount board start to suffer the ill effects of humidity. They seem to develop d ark spots that look like mold or mil dew. The prints are archivally processed a nd I use only 100% rag boards. Once the process starts it is impossible to save them. Has anybody come across a solution to this problem?? Incidentially, the prints are also toned in selenium.
