Interesting. I only managed to get gritty, dirty, partial images. We must be doing something different (or maybe my paper was dodgy). I may try Platine again. Thanks.
I'm going to start with Platine as an alternate paper first - in the US, Buxton is ungodly expensive - I can buy a 30x44 inch sheet of Platine for half of what a sheet of 22x30 Buxton costs. Which, if you really want to use it, can be bought from Talas Online.
