I'll just paste in what I wrote before about the films apparent sharpness. '.... The second problem is not as fixable after you buy the film. The negs have very poor acutance. That is, the graphing of the densities across a sharp transition from very black subject to very light subject has rounded corners. In regular B&W, with the right choice of developers, you can round the corners off as well (solvent developers do this), have them sharp and close to right angles (D-76), or even enhance them and have a slight reverse kick (compensating developers such as Rodinal. Lack of acutance, or rather the lack of possibility of high acutance bothers me; that's why Kodachrome 64 (if I could find a reasonable place to process it) would still rank ahead of any of the E-6 film in my estimation. Even though tests show that many 100 ISO E-6 films resolve as much or more than K64, and Velvia definitely does, K64 looks just as sharp as Velvia in most circumstances even though it is not nearly as contrasty and grainier....' ie, T400CN just looks mushy under some circumstances, and there is not much you can do about it. * Henning J.
