thank you so much for comments. I kept about 17 undeveloped rolls int the fridge for about half a year (not a best approach) and I almost got used to the thought that I will not develop them ever because of the prices (7euro for a roll in Dublin +shipment). Lately I decided to give it a go and I got Tetenal E6 3bath kit and developed them on my own; cheaper and so much fun and anticipation. Though I am b&w guy I ordered more Velvia because as you say: Velvia FTW
