I'm guessing that the gesso on the front (and edges) would make the front (and edges) waterproof. For the back, a couple of coats of polyurethane might do it, or you could glue on some aluminum foil or a piece of plastic sheeting.

Hi John,Interesting idea replacing the wood with a cardboard substrate. But what to use to render the cardboard waterproof?This needs some thought. Cheers, Bogdan John Bower wrote:To avoid the wood, you can get canvas adhered to a cardboard substrate. It would seem that you could coat the back (the cardboard) with something to make it waterproof, apply the gesso to the front, then the liquid light to the gesso. --John Bower www.studioindiana.com On Apr 6, 2008, at 12:02 AM, Bogdan Karasek wrote:I've worked something out on paper but I haven't had a chance to try it out yet. I bought canvas that was already stretched on a 12"x12" wooden frame. I've already applied the Gesso, which is that white stuff you coat a canvas with to stop the paint from leaking through the canvas. I'm wondering if Liquid Light needs the Gesso or can be applied to the raw canvas directly. Do you use gelatin for the emulsion to adhere? One problem I foresee is putting the stretched canvas into the developer. The developer gets into the wood; will the stop penetrate and stop the developper action. Then the fixer, again, absorption by the wood. I don't know how the wood is going to react, will the chemicals wash out? There are two elements that have I have to take into consideration, the canvas and the wood. A regular paper print doesn't need a support. Maybe you can try using the canvas without stretching.-- ________________________________________________________________ Bogdan Karasek Montréal, Québec bogdan@xxxxxxxxxxxxxxx Canada www.bogdanphoto.com "I bear witness" ________________________________________________________________====================================================================== ======================================= To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
