Although I don't use sheet film myself, I might have some addresses for you. <ol> A very good professional shop is Foto Klein in Rotterdam (just a few yards from Central Station): info@fotoklein.nl/(0)104141344 ; I am sure they can help you. Capi Lux is a high end professional shop, both in Amsterdam and Rotterdam; can't find their addresses at the moment. They are somewhere on internet.
