Folks, I heard there were problems with Cranes 90pound cover and iron specks in materials purchased from Bostick and Sullivans. I went to Photographers Formulary to acquire Cranes from them in the hope that it would be a different batch. Alas, I am seeing the same problem. It's really disturbing to see black specks all over creamy white images. Is anyone else facing this challenge with Cranes?
