Last year I dry mounted two arial photos of a client's house on foam core. They were double matted and glazed with conservation clear glass. Last week I got them back. There appeared to be a very large bubble in each photo and it looked like the image had pulled away from the mounting tissue. The "bubble" had a hazy ring around it . When I removed it from the frame the photos seemed to still be intact to the mounting tissue and the tissue seemed to still be adhered to the foam core. Nevertheless I put it back in my vacu-seal to see if, indeed, there was a loss of adhesion. It came out looking exactly like it went in. There is still a large cloudy oval-ish shaped ring in the image. When it came in, I asked the customer if it had been exposed to direct sunlight and she says no. Is this a sign of some kind of condensation? I have no idea what is going on or how to fix it. Actually, I have the capability of reproducing the images but I need to know what's happening so I can advise my customer and/or revise my methods. Help!
