Hi all, since I moved to Mexico, shipping costs for materials are eating my lunch money. I usually have done the sizing with 250 bloom gelatine. Today I saw a box of unflavored Knox gelatine and decided to buy it and test to see if it will work for pt/pd but I would really appreciate to know the experiences of someone who has used it. What bloom is it? processing tips? did it change the color of your prints? etc, etc. Later...........
