Framing Question

[Naicidrac]

Hello,
now I am also a painter as well as photographer. I have frames oils, watercolors and even pastels. Now I like to make my pieces as archaic as possible. I know that when you place glass infront of the image there needs to be a small space with pastels. Does there need to be one with a photograph or can the image pay against the glass. I know if there is a humidity change then the paper image would stick to the glass.

Thanks for the help

I have seen photo stick to the glass, so I guess it can be a problem. Although, the photo is just a print and can usually be reproduced from the negative or digital file.

I think the best solution is to use a matte, it keeps the piece from touching the glass and usually looks better than just a frame anyway.
