Well, I just took an order to frame a photograph, 13x19 inches, and my customer wants it framed with 1/8" plastic spacers, UV clear glass, A/F foam core, and a square white 3/4" wood frame. She really hates when photos are wavy. Who doesn't?!! I personally hate it. Why spend the time and money to frame something that looks horrible. The question is.....How do I frame it with spacers so it is not wavy? I have used spacers a million times and with glossy photos it always ends up not perfect, so I need help. Sometimes it looks perfect and then the temperature or humidity changes, and then it gets wavy...I know not to make the frame too tight or too lose, and to not put the points in too hard....the photo is valuable so she doesn't want it drymounted.....HELP PLEASE! Tricks? THANKS in advance...LUKE ps. even matting glossy photos is tricky with these issues, especially if it is a large photo...
