I noticed that Kodak is offering a B&W film called Ektapan in various sizes incl uding 5x7 and 11x14. In the Kodak website it is touted as a fine grained film de signed for electronic flash portrature and commercial applications but can be sh ot with natural light. T Max RS developer is also one of the developers that can be used. Has anyone experience with this film that you can share with us? Many thanks.
