Set for 2 hour period. THE MAIN FAN SWITCH IS IN THE UPSTAIRS LAB SEE RED SWITCH TO THE RIGHT OF THE DOOR. USE SAME BW DARKROOM CODE TO GAIN ACCESS INSIDE DOOR. Slide 11 DARKROOM: FILM PROCESSING SINK AREA INCLUDES: D-76 DEV TMAX DEV STOP BATH FIXER HCA FILM WASH PHOTOFLO Slide 12 FILM PROCESSING CHEMICALS: D-76: stock solution (discarded after single use). TMAX: stock solution (discarded after single use). STOP (acetic acid): working solution FIXER: working solution HCA: working solution Slide 13 D-76 DEVELOPER DILUTE 1 to 1 1 part D-76 1 part Water (use pump to dispense D-76) Temp critical 68-75 Colder water flows from 4 central faucets (marked #3-#6) D-76 DEVELOPER DILUTE 1 to 1 1 part D-76 1 part Water (use pump to dispense D-76) Temp critical 68-75 Colder water flows from 4 central faucets (marked #3-#6) Slide 14 FOR REGULAR FILM DEVELOPMENT KODAK D-76 IS USED ONLY ONCE TO HAND DEVELOP FILM IN STEEL OR PLASTIC TANKS. STUDENTS MIX D-76 WITH WATER AT THE RATIO OF 1 PART D-76 TO 1 PART WATER THEN TOSS DOWN DRAIN AFTER SINGLE USE. FOR REGULAR FILM DEVELOPMENT KODAK D-76 IS USED ONLY ONCE TO HAND DEVELOP FILM IN STEEL OR PLASTIC TANKS. STUDENTS MIX D-76 WITH WATER AT THE RATIO OF 1 PART D-76 TO 1 PART WATER THEN TOSS DOWN DRAIN AFTER SINGLE USE. Slide 15 FOR PUSH-PROCESSING! KODAK TMAX IS USED ONLY ONCE TO HAND DEVELOP FILM IN STEEL OR PLASTIC TANKS. STUDENTS MIX TMAX WITH WATER AT THE RATIO OF 1 PART TMAX TO 4 PARTS WATER THEN TOSS DOWN DRAIN AFTER SINGLE USE. FOR PUSH-PROCESSING! KODAK TMAX IS USED ONLY ONCE TO HAND DEVELOP FILM IN STEEL OR PLASTIC TANKS. STUDENTS MIX TMAX WITH WATER AT THE RATIO OF 1 PART TMAX TO 4 PARTS WATER THEN TOSS DOWN DRAIN AFTER SINGLE USE. Slide 16 TMAX DEVELOPER for push-processing DILUTE 1 to 4 1 part TMAX 4 parts Water (use pump to dispense TMAX) Temp critical 68-75 Colder water flows from 4 central faucets (marked #3-#6) DILUTE 1 to 4 1 part TMAX 4 parts Water (use pump to dispense TMAX) Temp critical 68-75 Colder water flows from 4 central faucets (marked #3-#6) Slide 17 Monitor Chemistry When finished working, dispose of any chemical that YOU DILUTE from concentrate: D-76 and TMAX film developers DEKTOL paper developer HCA tray solution for prints D-76 and TMAX are one-shot developers that cannot be reused. Developers can be contaminated easily so be sure to rinse beakers before measuring.

RETURN STOP for PAPER process to 5 gallon STOP container on shelf. EXHAUSTED STOP STOP BATH that turns PURPLE in color is fully exhausted. The stop can be safely discarded as it is no longer acidic. RETURN STOP for FILM process to gallon film containers located in sink. RETURN STOP for PAPER process to 5 gallon STOP container on shelf. EXHAUSTED STOP STOP BATH that turns PURPLE in color is fully exhausted. The stop can be safely discarded as it is no longer acidic. Slide 19 VERIFYING THE FRESHNESS OF EACH CHEMICAL. FRESH STOP IS YELLOW. STOP THAT IS EXHAUSTED APPEARS PURPLE IN COLOR. IT IS RE-USED UNTIL THIS DISCOLORIZATION OCCURS. VERIFYING THE FRESHNESS OF EACH CHEMICAL. FRESH STOP IS YELLOW. STOP THAT IS EXHAUSTED APPEARS PURPLE IN COLOR. IT IS RE-USED UNTIL THIS DISCOLORIZATION OCCURS. Yellow/fresh Brown/ almost exhausted Purple/toss Slide 20 FIXER NEVER pour FIXER down the drain, as used fixer pollutes the environment RETURN FIXER for FILM process to gallon film containers located in sink. RETURN FIXER for PAPER process to 10 gallon USED paper fixer container on shelf NEVER pour FIXER down the drain, as used fixer pollutes the environment RETURN FIXER for FILM process to gallon film containers located in sink. RETURN FIXER for PAPER process to 10 gallon USED paper fixer container on shelf Slide 21 FIXER DISPOSAL EXHAUSTED FIXER: use hypocheck to check for exhaustion--the white cloud! FIXER DISPOSAL: pour into large containers for EXHAUSTED/ DEAD fixer EXHAUSTED FIXER: use hypocheck to check for exhaustion--the white cloud! FIXER DISPOSAL: pour into large containers for EXHAUSTED/ DEAD fixer Slide 22 VERIFYING THE FRESHNESS OF EACH CHEMICAL FRESH FIX IS CLEAR AND ALWAYS LOOKS THE SAME EVEN WHEN IT IS EXHAUSTED. 1 ounces of FIX MUST BE TESTED WITH 2-3 HYPOCHECK DROPS. A WHITE PRECIPITATE FORMS INDICATING EXHAUSTED FIX (image on next slide).

A WHITE PRECIPITATE FORMS INDICATING EXHAUSTED FIX (image on next slide). Slide 23 FRESH FIX IS CLEAR AND ALWAYS LOOKS THE SAME EVEN WHEN IT IS EXHAUSTED. 2 ounces of FIX MUST BE TESTED WITH 2-3 DROPS OF HYPOCHECK. A WHITE PRECIPITATE FORMS INDICATING EXHAUSTED FIX.

Slide 24 EXHAUSTED FIX IS DISPOSED OF IN A 5 GALLON CONTAINER & IS NOT TO BE TOSSED DOWN THE DRAIN. WE MUST COLLECT IT IN OUR EXHAUSTED/DEAD FIX CONTAINERS SO THAT ENVIRONMENTAL SAFETY MAY TREAT THE FIX. EXHAUSTED FIX IS DISPOSED OF IN A 5 GALLON CONTAINER & IS NOT TO BE TOSSED DOWN THE DRAIN. WE MUST COLLECT IT IN OUR EXHAUSTED/DEAD FIX CONTAINERS SO THAT ENVIRONMENTAL SAFETY MAY TREAT THE FIX. Slide 25 HCA REUSE solution from one gallon containers for FILM. DILUTE solution from concentrate for PRINT processing and discard after use. HCA acquires a STRONG PINK COLOR upon exhaustion--when it can be discarded. Hypo Clearing Agent facilitates removal of residual FIXER from the prints and film. REUSE solution from one gallon containers for FILM.

MIX IT WITH WATER AT THE RATIO OF 1 PART D-76 TO 1 PART WATER. TOSS AFTER USE. TMAX IS USED ONLY ONCE TO DEVELOP. MIX IT WITH WATER AT THE RATIO OF 1 PART TMAX TO 4 PARTS WATER. TOSS AFTER USE. STOP BATH THAT IS EXHAUSTED APPEARS PURPLE IN COLOR. REUSE STOP UNTIL THIS DISCOLORIZATION OCCURS. FIXER THAT IS EXHAUSTED FAILS THE HYPOCHECK TEST: TWO DROPS OF THE HYPOCHECK ADDED TO TWO OUNCES OF FIX WILL EITHER APPEAR CLEAR OR CAUSE A WHITE PRECIPITATE TO FORM. THE WHITE PRECIPITATE INDICATES AN EXHAUSTED FIX. FIXER IS RE-USED UNTIL IT FAILS THE HYPOCHECK TEST. HCA TURNS A DARK PINK COLOR WHEN EXHAUSTED. IT IS RE-USED UNTIL DISCOLORIZATION OCCURS. STOP AND HCA THAT IS EXHAUSTED CAN BE DISPOSED IN THE DRAIN. FIX MUST BE DISPOSED OF IN THE DEAD/EXHAUSTED FIX 5 GALLON CONTAINER AT THE FAR END OF THE LAB.
