Smaller amounts of working solutions can be mixed, but careful attention must be paid to the mixing ratios
Preparing less than 2.5 L:
- For 1000 ml – divide all volumes mentioned above by 2.5
- For 500 ml – divide all volumes mentioned above by 5
- Example: to make 1000 ml of Fixer instead of the full 2.5 L, mix 200 ml (500 ml divided by 2.5) of
- Fixer concentrate with 800 ml of water (2000 ml divided by 2.5)

- Chemistry c.in be used one-shot or replenished with the appropriate KODAK Color Negative replenisher solutions.
- Times include a 10-second drain time at the end of each step. Solution volume depends on the type of processor.
- Tube is loaded with film and ready for processing. Do not immerse the film in a warm water pre-soak. Warm-up step is done by warming the outside of the tube in a tempered water bath.
- Determine the correct time for your processor by running a test with your tube.
- If final rinse foaming in the tube is a problem, you can do the final rinse of the film in a separate tank.
Small Tank
| Solution/Step | Time* (min:sec) | Temperature oc (OF) | Comments |
| Developer | 3:15 | 37-39 (99-102) | Initial agitation for 30 seconds, followed by 2 seconds of agitation every 15 seconds. |
| Bleach | 6:30 | 24 · 41 (75 -105) | Initial agitation for 30 seconds, followed by 2 seconds of agitation every 30 seconds. |
| Wash | 1:30 | 24 -41 (75 -105) | Use running-water wash at a rate that will fill tank every 4 seconds. Or fill tank with water, agitate for 5 seconds, and dump. Repeat cycle throughout wash time. |
| Fixer | 6:30 | 24 -41 (75 -105) | Initial agitation for 30 seconds, followed by 5 seconds of agitation every 30 seconds. |
| Wash | 3:15 | 24 · 41 (75 -105) | Repeat procedure used for first wash. |
| Final Rinse | 1:30 | 24 · 41 (75-105) | Initial agitation for 30 seconds; no further agitation required. |
| Dry | As needed | 24 · 43 (75 -110) | Remove film from reel. and hang film to dry in dust-free place or drying cabinet. Attach film clip to top to hang it, and add weighted clip to bottom to prevent curl. |
Agitate the tank by turning the tank over (inverting it) with a slight rotation (quarter turn), then return the tank to an upright position. Do this at a rate of one agitation cycle per second.
Storage Conditions
| Chemical | Concentrate Once Opened | Working Solution |
| Color Developer Bleach | 12 weeks 24weeks | 1 week 24 weeks |
| Fixer | 24weeks | 24weeks |
| Final Rinse | Indefinite | Indefinite |
Care should be taken to store the solutions in clean bottles with as much air expelled as possible. Keep concentrates in their original packaging when mixing less than the full volume of the kit.

Troubleshooting
| Fault | Possible Cause | Remedy |
| Negative too dark | Overexposure in camera Developing time of color developer too long Contamination of color developer | Check camera and exposure Shorten develop;ng ,;me by 15·30s Rinse equipment and reels thoroughly |
| Negative too light | Underexposure in camera Prewash/Prewarming of the tank has been omitted Developing time of color deve oper too short | Check camera and exposure. Add a prewash time of 3 to 5 min. to the program Extend developing time by 15-30s |
| Uneven color areas, streaks and stripes | Insufficient filling ciuantity Prewash has been omitted
Color developer was Poured in too slowly | Check filling amount Add a prewash time of 3 to 5 min. to the program. Pour in the color developer Quickly |
| Color fog | Mixing vessels of the proees$0r are not clean Contamination of the developer by other chemicals. | Use individual mixing vessels and mixing rods for each bath |
| Drying spots on the dry film | Tap water is too hard when preparing the stabilizer bath | Mix tap water with distilled or or demineralized water in the proportion 1:2 |
| Negatives appear magenta and print cyan | Insufficient bleach and fixing | Re-bleach and fix the film and then re-dry |
