"Excellent value for money with good shelf life. I have had almost 3 months life when mixed and topped off with inert gas for storage. "

"Very happy with this kit, as well as the usual prompt service and delivery from FirstCall. Very clear, straightforward instructions. Had no issues with developing. Only complaint is that you’re only given enough stabiliser to make 500ml, so not enough to fill my 650ml tank but I simply over-diluted to get the amount I wanted. However this left drying streaks which I think could have been avoided having not to over dilute the stabiliser. None the less, very happy with the kit and would definitely recommend to anyone needing to develop C-41"

"Well packed, on time and in good condition ????"

"Great Product for developing if you get your blance right and your Time/Temp masterd but if your first time be awere you will have spare chemicals and not equal developing chemicals so bare that in mind outher wise make shure to print this PDF off it will save you https://drive.google.com/file/d/1-uIesXKVuX-78r5-8YT9whal7C_2oVHy/view?usp=sharing and good luck with your Developing!"

"I used this kit for my first attempt of developing photos at home, and it was instant success. Since then I developed another roll and that looked great too. One tip: Since it's really hard to consistently maintain temperatures stated on the labels, I decided to interpolate temperature/timing curves for color developer, bleach and fixer (stabilizer is not really sensitive to this). I use 1L chemical bottles to store the adequately diluted chemicals. Then when developing, instead of trying to shoot for a specific temperature, I put all my chemical bottles in a 10L stainless steel pot and pour warm tap water (~45C) around them. Then I wait and replace the water after ~10-15 minutes (which time I use to put my film on the reel in the dark). Then before using the chemicals, I measure the color developer's temperature and read timing value from my hand-made interpolation chart stored in Google Sheets. This avoids the problems of trying to aim for a specific temperature. I just go with something that's "warm enough" and use the interpolated times. If you want to interpolate the temperature vs. timing curve for yourself, I recommend constructing a Lagrange polynomial (https://en.wikipedia.org/wiki/Lagrange_polynomial) from the 4 temperature-timing pairs that's on the label of the chemicals. This is simple enough and smooth (it is unlikely that the actual curve being estimated is non-smooth). Just beware that these polynomials are not good for extrapolation, so anything out of the temperatue range that is covered on the label would be inaccurate."

"OK - SAME OLD KIND OF DEVELOPER - I HAD NO ISSUES UTILIZING IT - ONLY THAT I COULDN'T REPRODUCE THERESULTS I HAVE MANAGED TO CREATE IN THE PAST - WHERE, DEPENDING ON RATIO OF 300ML SOLUTION, I HAVE CREATED A DECENT RENDERING OF COLOUR IMAGERY. IN THE MAIN, I WILL UTILIZE THIS DEVELOPER AGAIN, BUT I NEED TO SHHOOT IMAGES I CARE ABOUT, NOT MERELY BANAL AND DULL IMAGERY, AND RENDER THEM WORTHY OF PRINTING UNDER ENLARGER. YEAH; PRICE COULD BE MORE COMPETITIVE AND POSTAGE COULD BE LESS THAN IT IS - BUT, YEAH, I LIKE YOUR COMPANY."

"It was my first time trying out colour negative developing and I plumped for this kit. I have found it very easy to use, it does exactly what it promises and I'll definitely be buying another when this first one is used up."

By J mckenzie on 27th June 2016

"Good quality product, adequate instructions and not too much unnecessary packaging. I will buy this again."

"Excellent Service, Excellent Product Thanks"

Manufacturer’s Description

Order of processing:
1. Color development may be stopped undyed with acetic acid
2. Bleaching
3. Fixing
4. Stabilizing

C-41 COLOR DEVELOPER:
Approach example for 250ml working solution:
Pre-soaking with tap water, already tempered to exactly 38?C!
172.5ml of water, tempered at 38?C + 25,0ml C-41 color developer Part A, + 25.0ml C-41 color developer Part B, + 25,0ml C-41 color developer Part C, + 2.5ml C-41 color starter, mix thoroughy until ready 250ml working solution.
Processing time: 3 min 15 sec in constant motion.
Temperature: 37.8?C +/- 0.3?C. Then perhaps a stop bath based on acetic acid without color indicator.

C-41 BLEACHING BATH:
Approach example for 250ml working solution:
180.0ml water + 70.0ml C-41 bleach bath.
Processing time: 3 min 0 sec - 4 min 20 sec in constant motion.
Temperature: 32?C - 40?C.

C-41 FIXING BATH:
Approach example for 250ml working solution:
200.0ml water + 50.0ml C-41 fixing bath.
Processing time: 4 min 20 sc - 6 min 30 sec in constant motion.
Temperature: 32?C - 40?C.

C-41 STABILIZING BATH:
Approach example fpr 250ml working solution:
225.0ml water, tempered to 38?C + 25.0ml stabilizing bath, stir
Processing time: 1 min 0 sec - 3 min 20 sc in constant motion.
Temperature: 32?C - 40?C.

CAPACITY:
The color developer, working solution, example 250ml: One can at least process 5 films in a approach of 250ml. This requires a rapid processing (within 6 hours) ahead. Between the working steps, the solutions should be sealed and protected from air carriers.
The bleaching bath, ready-made solution, 250ml example: One can process at least 10 films in a approach of 250ml. The little use solution should be kept in well-sealed bottles for several weeks.
The stabilizing bath, ready-made solution, example 250ml: One can at least process 10 films in a approach of 250ml. The littel use solution, can be kept in well-sealed bottles for several weeks.
