To get the best from Pan F it's important to do your own film speed/development time tests. These will affect the shadow detail as well as the contrast and it's important to get the balance right.

Slower films need careful handling to get the best sharpness, you have to use slower shutter speeds and wider apertures and that doesn't help. So a good tripod and mirror lock (if you can) makes a huge difference.

Way back in the early 1960's Geoffrey Crawley wrote about getting the ultimate in sharpness & resolution with Panatomic X (but applicable to Pan F as well) and he commented that you needed good lenses, no vibrations, optimal exposre etc.
