No Compromises - Cs6 3-Bath Process vs. E6 6-Bath Processing
Posted by CineStill on
With the Cs6 "Creative Slide" process the number of processing baths for E-6 film is reduced from 6 to 3. The reversal step occurs during color development in a Color&Reversal bath, and the pre-bleach, bleach steps are combined with the fixing step in a Bleaches&Fixer bath. People often wonder, "What are the compromises with combined processing baths?", such as the Cr6 "Color&Reversal" 2-In-1 Slide Solution or the Bf6 "Bleaches&Fixer" 3-In-1 Slide Solution. The reality is that there are no compromises between fresh Cs6 and carefully replenished E-6 chemistry.
Just see for yourself! We bracketed exposures of an extreme lighting situation just before sunset, with cool skylight and warm backlight. Snip tests were made and processed in each of our 1st developers at 104ºf and the remaining 2 Cs6 baths at ~85-100ºf in a Patterson tank. The remaining film was sent to The Darkroom photo lab and processed with the 6-bath E-6 process. The Darkroom specializes in professional film developing and scanning. Their Sitte Tischer TruTrak dip & dunk processor maintains high professional standards with constant process control standards. All frames were scanned on the Skier Sunray Box with a Canon 5D mk2 with all the same settings and corrections.

There is a lot of conjecture and skepticism out there regarding the archival stability and efficacy of "hobby" type chemistry kits, especially when it comes to slide processing. Some rationalize that, "Professional labs must prefer the 6-bath E-6 process because it is superior." or posit, "Why then don't pro labs use combined processing baths like blix?" Well, that is not the whole story...

Latitude for Days - D9 DynamicChrome vs. E6 Dynamic-Range
Posted by CineStill on
D9 “DynamicChrome” Warm-Tone Dynamic 1st Developer renders approximately 9+ stops of usable dynamic-range while maintaining rich warm-tones and vibrant color-contrast with preserved highlight and shadow detail (optimized for scanning) for a more cinematic look. Mixed stock solution can be measured out at 1/2 the tank capacity and diluted 1+1 with water to make a working solution for normal warm-tone development. Dilute 1+2 or 1+3 with water for further preserved highlight detail and a more neutral-tone daylight color balance.
But is extending the dynamic range of slides really possible? Of course! That's why we are so excited. When a piece of emulsion is struck by light, trace amounts of silver harden. It would take an insane amount of overexposure to reach the maximum density of the emulsion. But in order to make the hardened silver visible it needs to be amplified with a developer. If you develop it past the Dmax of the film you will lose detail. The key is to slow down development in the highlights while developing the shadows enough to be visible. While it is difficult to increase the shadow detail that is exposed below the base fog of the film, without eliminating it's beautiful inky blacks, we have harnessed the highlight latitude of slide film beyond imagination.
We bracketed exposures by 2 stops under to show how many stops of additional dynamic-range are retained in the highlights. Snip tests were made and processed in each D9 dilution at 104ºf and the remaining 2 Cs6 baths at ~85-100ºf in a Patterson tank. The remaining film was sent to The Darkroom photo lab and processed with the 6-bath E-6 process. The Darkroom specializes in professional film developing and scanning. Their Sitte Tischer TruTrak dip & dunk processor maintains high professional standards with constant process control standards.
