I think the shadow density is good, as i expose for it (mostly over expose) and when i print i usually get good detail, with great 'fall off' into deeper blacks. Now, sometimes i used to wish there was more shadow detail, and so i kept purposefully overexposing. By using pan f at ASA25, now though i have it set in camera at around ASA 32 and don't purposefully overexpose as much, but it amounts to about the same thing. the problem had before was my i used water temperatures that were all over the place. now i make sure it's at 68 degrees. I'm happy with the results, but would i be happier otherwise?
