I wouldn't mind trying something like this http://www.alternativephotography.co...he_forest.html

I took a similar kind of photograph today with this print in mind, looking at silverprint but I can't find any liquid emulsion, they surely must have it though. What's it called, what's the best stuff to get? Also do you have any idea what this is printed on? I was thinking of buying cheapy canvases, what is the background coloured with?
