An ex-pro here. I quit photography as a career at age 30 (!) and returned to school to do a finance degree. My present position allows me to indulge in what is now my hobby to my heart's content. I don't get terribly concerned about cost; most of what gets my blood up is the diminishing options available to analog shooters.
While I continue to shoot both E6 color (working on a HUGE stash of E100G/VS in my deep-freeze in 35mm and 120) and black and white (I am a huge fan of PanF Plus/FP4 Plus/HP5 Plus and Tri-X), my darkroom (a.k.a. the guest bathroom in my townhouse) is set up to do only the latter. When E6 has run its course, all my analog shooting will be in monochrome.
