It maybe the camera ? Its a Nikon F65 and i have it set to auto
Problem with that is the camera chooses the f/stop for you,
i am going to try it in manual and make my own choices.

Also i have just acquired a Minolta X-300, that's a manual camera, so that needs a
go with some film in it also.

As for enlarger lens it go's to f16 if i remember
it's a 50mm f2.8 El-Nikkor and i have a f4 El-Nikkor also

As for the Kentmere film, on the Massive dev chart it states 7.5mins using Rodinal (r09)
for the 400 ISO film so thats what i did ?
