35mm, 120, and 4x5 black-and-white stocks normally carried, including HP5 Plus, Tri-X, Delta, T-Max, FP4 Plus, and sheet film when distributor cartons are moving.

Supplies With Stock Counts Attached
Photo Source Book is not trying to look like a giant warehouse. The point is narrower and more useful: the black-and-white materials Rochester darkrooms actually need, with clear prices, refrigerated film, winter chemistry cautions, and used parts that have been tested.
Inventory Overview
The Normal Shelf Is Technical, Not Romantic
The counter keeps black-and-white basics deep enough for coursework, home darkrooms, and archive jobs, then special-orders the odd sizes without pretending every carton is sitting in the back room.
RC and fiber papers in common student and working sizes: 5x7, 8x10, 11x14, and 16x20. Pearl and glossy surfaces move fastest.
D-76, paper developers, stop bath, rapid fixer, hypo clear, selenium toner by request, graduates, bottles, and storage labels.
Trays, tongs, thermometers, changing bags, safelight lamps, grain focusers, easels, timers, and sleeves for jobs that need clean handling.
Negative pages, print sleeves, glassine, binder boxes, interleaving tissue, cotton gloves, and storage materials for school and archive staff.
Bulbs, condensers, negative carriers, timers, enlarger lenses, lens boards, and odd Durst, Beseler, Omega, and LPL parts when tested stock appears.
| Format | Normally Carried | Example Price | Storage Note |

| 120 | Kodak Tri-X 400 | $8.95 per roll | Cold storage, counted before class-term weekends |

Paper And Chemistry
Paper Boxes Are Sold Like Materials, Not Decor
Ilford Multigrade RC Deluxe pearl 8x10, 25 sheets is $28.50. RC paper is usually the fastest shelf mover for student labs. Fiber paper, 11x14 cases, 16x20 boxes, and alternate surfaces are handled through the Monday special-order cutoff when the shelf count is thin.
Chemistry includes Kodak D-76 powder to make 1 gallon at $13.25 and Ilford Rapid Fixer 1 liter at $18.40. Developer, stop, fixer, hypo clear, graduates, storage bottles, and labels can be bundled for home darkroom resets.
Winter Shipping
Liquid chemistry is not shipped in winter if the overnight forecast on the route is below 20 degrees Fahrenheit. Powder chemistry and counter pickup are the safer route when the lake-effect forecast gets ugly.
Used Parts Ledger
A cheap timer that drifts is not cheap after the second ruined box of paper.
Inspected Beats Pretty
Negative Carriers
Checked for format, seating, alignment surfaces, and filed edges that could scratch film.
Enlarger Lenses
Inspected for haze, fungus, aperture movement, and practical coverage rather than shelf shine.
Timers And Easels
Timers are tested for repeatability. Easels are checked for blades that hold square and do not creep.
Trays And Safelights
Trays are checked for cracks and residue. Safelights are sold only when the filter and lamp make sense together.
Grain Focusers
Mirrors, bases, and focus clarity are checked because a foggy focuser makes sharp work slow.
Used enlarger parts are tested before sale. Bulbs, condensers, negative carriers, and timers are sold as inspected used items with a 7-day return window.
