I'm a new oldtimer - have been out of B&W photo for some 15 yrs; now I'm trying to return, and I hope the nice people in this site will help with my silly mistakes...
I use very up to date equipment - Pentax Spotmatic, ESII and Takumar lenses. Opemus III enlarger - some 30 yrs old, and very high tech (-:

Thanks and regards,
