I forgot Polaroid. I remember hearing about InnovisCoat but thought they had stopped. What labels do they sell their film under?
I knew Instax was popular. I had no idea it was that popular!
Could you elaborate on some of these projects/products?
Who managed to create modern, high-quality slide film with lesser means and experience recently?
Well yes but I imagine the "lesser means" was referred to people making film with lesser means than Ferrania, I'm not sure Kodak qualifies as "lesser means" in this case, even it if is surely "reduced means" from 2003.
Really‽ Significantly? What are you comparing to? Royal, Gold Ektar 25?- new E100 has a bit less resolution than former E100G (that is a pattern we've seen also with Portra 400 and Ektar having significant lower resolution compared to equivalent forerunners)
Really‽ Significantly? What are you comparing to? Royal, Gold Ektar 25?
Looking in a pretty good microscope I'd say Ektar is not very far off from TMax 100.
What exactly would you say the difference is? Why is it? Is there good reasons? IE was it done as a tradeoff, getting other things in return?
That was fascinating, thanks. I'm sure these balancing acts are not easy for manufacturers.Even Kodak themselves have advertised Ektar 100 only as "finest grain ISO 100/21° film. But never as highest resolution or sharpest ISO 100/21° negative film.
They know why: Because Ektar 100 was designed with focus on grain, but not with priority for resolution and sharpness.
Here are the results for Ektar and other ISO 100/21° CN films from my standardized resolution tests (you know my procedure, so I don't repeat it here again):
- CineStill 50D: 105 – 115 lp/mm
- Kodak Ektar 100: 90 – 105 Lp/mm
- Kodak Farbwelt 100: 105 – 115 Lp/mm (Gold 100 for the German speaking market)
- Fujicolor 100: 120 – 130 Lp/mm
- Fuji Superia Reala 100: 105 – 115 Lp/mm
- Fuji Pro 160 C: 100 – 115 Lp/mm
- Kodak Portra 160 NC-2: 100 – 115 Lp/mm
- Kodak Portra 160 VC-2: 105 – 115 Lp/mm
- Kodak Portra 160 New: 105 – 115 Lp/mm
And for your opinion that "Ektar is not very far off from T-Max 100": My test results demonstrate a completely different result, as TMX has achieved 135 - 150 Lp/mm in my test. Ektar cannot compete at all concerning resolution and sharpness with TMX. TMX has the highest resolution of all ISO 100/21° BW films (but Delta 100 coming close).
Same is valid for ISO 100/21° colour reversal films: Former E100G, Elitechrome 100, Provia 100F, Sensia 100, Astia 100F , the Velvias, all are in the 120-135 Lp/mm range, surpassing Ektar significantly. Also new E100, with about 110-120 Lp/mm.
Resolution is the weak spot of Ektar compared to all other colour films in that class. To be absolutely sure I have done the Ektar tests 6x, all with different batches. Always the same result.
As for Portra 400:
- Kodak Portra 400 NC-3: 100 – 110 Lp/mm
- Kodak Portra 400 (new): 80 – 100 Lp/mm
Why have these three newer / younger Kodak films finer grain than their forerunners, but worse resolution (and sometimes also less sharpness)?
I don't know for sure, but that may be a possible reason:
All these films were advertised as "optimized for scanning". Generally I don't care much for marketing statements. Especially if it is not further underlined with details as in this case.
But Kodak is well aware that most of the films, especially CN films, are scanned nowadays. But they of course also know that all current scanners fail concerning higher resolution. None of it is capable to fully resolve all the detail which is really on the film (I have tested that several times over the years, too). Even the highest resolving scanners - drum scanners - cannot fully resolve all details on the film, and have lower resolution capacity than classic optical enlarging and slide projection.
So maybe Kodak decided "if the majority of photographers destroy the high resolution on film anyway by using the lower resolving imaging chain scanning, then we don't need to care for high resolution anyway."
But finer grain is even seen on 'bad scanners'. Even on the very low resolution flatbed scanners.
So they decided to concentrate on finer grain, and 'sacrificed' resolution. Well, again as said above, that is a hypothesis, a possible reason why they went that way.
I am not a fan of this approach, and prefer those films in Kodak's film programme which combine excellent fineness of grain with excellent resolution and sharpness, like TMX, TMY-2, TMZ and Portra 160. Because I like larger prints.

Thanks Henning! You’re a prince. Really!
I’m surprised that you say slide is generally higher resolution than C41.
That has been rebuffed by many people in the know over the years, including PE AFAIR.
Well, I love to project slide. No realistic print I’ll make for personal use, will ever get close to the size I can project.Thank you.
Well, just project a slide from the current reversal films in your home on 1.5m - 2m width, and make a print from a colour negative film of the same size, and compare them side by side. Then you will see it immediately that the reversal film offers significantly better detail rendition.
Professional photographers have made slide / audiovision shows in front of big audiances for decades, with slides projected on several meters width in excellent quality. A print of that size from CN film (yes, that is made for certain applications) offers less detail in comparison.
The excellent detail rendition of colour reversal film is also one of the reasons why reversal film has been the dominant film type in professional photography for decades before digital. All advertizing shots (e.g. for products and catalogs), prof. travel photography, architecture, nature and wildlife has been almost exclusively shot on reversal film. Negative film was only used as main medium for weddings (as prints were wanted by the couples), portraits when prints were wanted, and in the 90ies and early 00ies for newspapers.
When prof. photographers wanted the best detail rendition and resolution they used Kodachrome 25, or Kodachrome 64 when higher sensitivity was needed. Both were then replaced by Velvia, Provia, Astia and the latest Ektachromes which all surpassed Kodachrome in detail rendition (and other parameters).
Those who tested films on a scientific basis all get the result of the resolution advantage of reversal film. That is also partly because one strengths of them is the excellent resolution at low object contrasts. For example all Velvias can resolve about 80-85 Lp/mm at an object contrast of only 1.6:1. No colour negative film has ever come close to that outstanding value.
That has been rebuffed by people who have never done proper tests by themselves.
And for example Carl Zeiss has tested Velvia 50 and 100 and got 160 and 170 Lp/mm (they have used a bit higher object contrast than I have in my tests, therefore their higher values). None of the colour negative films they have tested with identical film speed have reached such high values.
And concerning Ron Mowrey / PE:
He retired in 1997. But all of the current reversal films we have today with their significantly improved technology (with Velvia 50 being a special case because of its slight overhaul and reintroduction in 2006/07) were introduced later.
Ron has never done detailed resolution tests of Provia 100F, Astia 100F, Velvia 100F and 100, E100G(X), Provia 400X, RVP 50. I have talked to him. He had stopped using reversal film even before his retirement. He found prints more convenient for his personal use.
Best regards,
Henning
Well, I love to project slide. No realistic print I’ll make for personal use, will ever get close to the size I can project.
Even half frame slide hold its own at wall projection sizes. 6x6 is out of this world.
And (real) contrast is better than any other display medium. Full stop.
If you say so, I believe you.
Funny though that PE did work on Kodachrome, and not being that interested or even having tested slide.
Maybe he was more into colour science? But
I always thought that the CN look was due to it not being a first generation copy like slide though.
Soapbox‽ Where did that come from?Get off your soapbox! PE did a lot of work testing slides films including Ektachrome. How about sticking to the facts instead of making things up.
Which Fujicolor 100 is that?- CineStill 50D: 105 – 115 lp/mm
- Kodak Ektar 100: 90 – 105 Lp/mm
- Kodak Farbwelt 100: 105 – 115 Lp/mm (Gold 100 for the German speaking market)
- Fujicolor 100: 120 – 130 Lp/mm
- Fuji Superia Reala 100: 105 – 115 Lp/mm
- Fuji Pro 160 C: 100 – 115 Lp/mm
- Kodak Portra 160 NC-2: 100 – 115 Lp/mm
- Kodak Portra 160 VC-2: 105 – 115 Lp/mm
- Kodak Portra 160 New: 105 – 115 Lp/mm
I think Henning's comments respecting PE make sense.
After all, he did prefer modern Ektachrome to Kodachrome!
I doubt that he did line pair comparative resolution tests after his retirement.
As a resource, he could offer a lot more about how and why then about detailed comparisons between current offerings. That is definitely more in Henning's area.
Which Fujicolor 100 is that?
And do you have any idea about how it achieves such high resolution?
Quite amazing from what is normally regarded as a budget(ish) film.
The Orwo news I saw online, and it would be interesting that the Inoviscoad/FIlmoted (?) product to be re-released under an Orwo brand, even if the rest is avaialble as Lomography at a very marked up price. As a comment to the appreciation of cameras, I am even trying to find a cheap, as in very cheap decent m42 standard lens (Helios 44, Takumars) and so far haven't been lucky at the giveaway prices one would have gotten them years ago.No, they have not stopped. So far they have operated as a contract / OEM manufacturer for other brands like e.g. Lomography and Bergger. Because of changed ownership structure and new cooperation with FilmoTec (see their official announcements) it can be expected that in the future some of their products are also offered under the ORWO brand name (if the development efforts are successful).

I've been wanting to try S100 for some time.Well, this film - which is most probably the original Superia 100 version - has been offered by Fujifilm in different names and boxes on different markets and in different periods. Here in Germany and Europe it was offered as Fujicolor 100 about a decade ago. And it has been offered in Japan as Fujicolor "Industrial / Business" 100 in bigger packs to wholesalers. Meanwhile it has got a new name and box design and is sold as Fujicolor S100 in Japan.
Concerning resolution this is currently the colour negative film which come closest in resolution of middle object contrast detail to ISO 100/21° colour reversal films (the reversal films keep their advantage at low and very high object contrast details).
This is an "amateur film", and these have generally a bit higher contrast as the professional line films. And that has a positive impact on resolution. And in general all the Fujifilm amateur films are very good concerning resolution and sharpness (and surpassing their Kodak counterparts a bit).
The Fujicolor 100 / S100 is a kind of "hidden treasure" on the current market, because besides its excellent detail rendition this film also has a very natural, pleasant colour rendition.
Best regards,
Henning
No of course not. And if you do, you'll probably have to pay through the nose, because some poor sap thought he made a conniving investment by buying home a brick of S100, and is trying to sell it as an exotic specialty at triple the price.Can you get Fuji S100 in the United States? I've never seen it for sale.
