I see Silbersalz35 remarkable and unique for this reasons:
1) PRICE / roll
Buying 4 rolls cost me 60,71 EUR delivered (German VAT inc.). Buying 4 rolls of CineStill Xpro C-41 800T cost me 61,10 EUR delivered (Slovenian VAT inc.). I can also pick up film myself in both cases, but for Silbersaltz35 that means 1400 km from my place near Ljubljana to Stuttgart, other films I need to drive "only" 50 km to nearest local store. In both cases online delivery is cheaper. I can also buy on my business account in both cases, so I have VAT deducted. So in that case Silbersalz35 total price is €48,23 and CineStill total price is €50,10 - in either case Silbersalz35 is cheaper. Not by much, but it is. Most other top rated films I used are somewhere same price per 4 rolls delivered (Portra, Ektar, Pro400H) or even much more expensive (Lomo, Provia, Velvia). In both cases delivery cost is the same for up to 6 packs of 4, so cost per roll drops as more rolls are ordered in the same time.
2) true ECN2 PROCESSING
I tested CineStill 800T and in my experience it is the worst film I ever shoot. Washed colors, grainy as pushed Delta 3200, ugly color cast in shadows and ugly halation around anything remotelly red. It's like cheap digital camera at insane ISO, but with lower resolution too. I will never buy it again since it one of the more expensive film. As I searched throughout the internet, ECN-2 processing is superior to C-41 and processing Vision3 in C-41 is only "good enough" approximation, not to produce same quality. A link above show
processing of CineStill in both C41 vs ECN-2 to be identical, but there they already process film that was preprocessed before exposure (stripping halation layer). Even on that picture it can be seen that C-41 process wash out some highlights, which have less saturation and are brighter. A Yutube video shown
prove that even further when processing original Vision 3 film vs CineStill processed. Original is superior in several areas, mostly in shadows and halation. Shadows shows exactly the same ugly blue grainy look as I experienced from my test. While original have non of that, saturation of highlights is much better and no halation. So no question to me what to pick in the future.
3) Cost of processing for Silbersaltz35 = ZERO.
Processing of 4 rolls of any other film cost me €12 + 2x drive to the lab (total 2h of time and 100 km driven). That is just processing. Than I have several options for scanning: Whole roll at the time of processing on Fuji scanner cost me €10 / roll. I can also scan home at flatbed for free (but huge time pain) or send film to another lab to scan it with Hasselblad drum scanner for €1 per selected frame! So scanning of 4 rolls can cost from €52 for JEPG scans from FujiFrontier up to €156 for Hasselblad drum scans if all 144 frames would be scan worthy!! Plus all driving.
Did I mention that scanning with Silbersaltz35 option is in the price of rolls that are still cheaper than CineStill rolls alone? Sending film back to Germany with tracking cost me 8 EUR flat and that is it.
4) CINTEL high end scanning and high end files delivered.
As I can see the samples that scanning isat the upper level that exists today. They also have calibrated color science per stock which they include. You can use it in Lightroom. Also you have JPEG preview files to see what files you actually like and download only those. Editing true wide DR files is like have digital raw files vs baked JPEGs which soon fell apart when edited. I think quality can not even compare to any other scanning method I tried other than Hasselblad method which is 35 times more expensive. I stopped having film scanned in FujiFilm scanners in developing labs because I hate the auto correction of highlights which does bad on clouds and all sort of unvanted enhancements. There is no hope to be scanned with any care from operator. It's automated process. Also resolution of end files is up to 9 megapixels, while Silbersaltz35 claim 21 megapixels.
COCLUSION:
Purchase of 4 rolls of CIneStill, developing and scanning in the local lab cost me 61+12+40 = €113 or €0.79 per frame.
Purchase of 4 rolls of CIneStill, developing in the local lab and Hasselblad scanning cost me 61+12+144 = €217 or €1.50 per frame.
Purchase of 4 rolls of
Silbersaltz35, and sending for proper processing and high end scanning cost me 61+8 = €69 or
€0.48 per frame.
Even if buying cheapest films at €5 per roll it would still cost me much more per frame than Silbersaltz35. When you calculate ALL costs from purchase to have frames in digital form, Silbersaltz35 seems the cheapest option at probably the best quality at the same time. How cheaper are other custom cine-film packaged in 35 mm? How much cheaper one can develop them at home. How faster or better one can scan them at home. Unless owning a proper equipped lab I think every other option is more expensive and time consuming and may result in poorer quality.
That is my opinion.
