Also, why do you feel Provia is better film than Ektachrome?

I don't "feel", I have done many direct comparison tests. With the results that Provia 100F has much better sharpness, higher resolution, a color rendition I prefer (E100 is a bit too cool for my taste).
And Provia is a real ISO 100 film. E100 has only 80. That is not only my test result, but countless other experienced photographers have got the same result (in other forums there are long threads with photographers reporting that).
And Fuji has the much superior 120 film finishing, I love the easy end seal and easys loading solution.

I've shot both and found that E100 shows the greens more green and the reds redder. Provia tends to show the reds more orangey.

I cannot confirm that at all. I get very precise green rendition and excellent reds with Provia (no orange cast at all).

Good morning Alan. It seems that you've heard enough testimonials, and criteria, and experiences that are saying about the same, perhaps in slightly different ways. It might be in your best interest to synthesize your research! If you really want to use your digital camera and use "blinkies" for assistance you really need to just try it and verify. Asking the same question repeatedly probably isn't going to get you any additional information. Just a suggestion from someone who is like-minded about research. I found out a long time ago that the secret to being a life-long researcher is knowing when to stop the research and turn it into practical experience. :smile:

I understand getting the ground reading is important so it's exposed correctly. However, how do you check you're not going to blow out the sky when you recompose to include it? If you're shooting let's say late in the day, the ground can be much darker yet the sky is still fully lit. You'll overexpose the sky losing all detail. So you'll either need to eliminate it from the picture or add a GND.

I do not check the sky and I never worry about the sky. The sky fall where it is suppose to probably because I use a skylight or UV filter.

Film-Niko : your opinion about current Ektachrome is simply off. Just exactly how did you test it? Please describe your methodology all the way from exposure to final evalution. I seriously doubt you're better equipped to do that than the manufacturer itself, or those otherwise with serious sensitometric equipment, or even know what a truly controlled test involves. And Provia is NOT finer grained.
Fuji's finest chrome film was Astia 100F, now obsolete, followed by certain Velvia products. But really, we're speaking about dye cloud structure, and not grain in the same sense as black and white film. It is a little cooler, being precisely balanced to Kodak's 5500K standard of Daylight. Provia seems more like 5200K balanced. Astia and its lab derivatives had the most accurate palette of any chrome films, followed by certain specialized Kodak lab films now also out of production.

And another photrio member who is not reading precisely.......it is so sad.
I have not written that Provia 100F has finer grain than E100!! Concerning grain both are on the same level, RMS 8.
I have written that Provia 100F has better sharpness. That is confirmed by Kodak in the E100 data sheet, as E100 has a lower MTF at spatial frequencies determing sharpness.
I have shot resolution test charts and then compared the results by using higher-magnification loupes, microscope and in projection with 2 2 meters width.
The advantage in sharpness and resolution for Provia 100F is clearly visible.


Fuji's finest chrome film was Astia 100F, now obsolete, followed by certain Velvia products.

That is correct, Astia has been the finest grain film. But the Velvias are not finer grained than for example Provia: Velvia 50 has a RMS of 9, Velvia 100 and 100F a RMS 8, Provia RMS of 8, Astia RMS of 7. The lower the RMS, the finer the grain.
I have used Astia by myself in the past. Still a bit of it in the freezer. But Astia has not been the topic here.

But really, we're speaking about dye cloud structure, and not grain in the same sense as black and white film. It is a little cooler, being precisely balanced to Kodak's 5500K standard of Daylight. Provia seems more like 5200K balanced.

I have to disagree here: Astia is not cooler than Provia, as Astia was mainly designed for portrait and fashion, and with optimal skin tone reproduction. And therefore a little bit warmer. Not much, but visible in direct comparison. It is also official by Fuji, as I have talked about that with a Fuji rep when this film was introduced.

And other such snarky commentaries.


What’s even more sad are the Photrio members who feel entitled (or the need) to express themselves so rudely rather than simply address the misunderstanding or difference of opinion.

But I think you mean “accurately” rather than “precisely “…

Sorry, but in the last days several members here have made claims that I have allegedly written something which I have absolutely not.
Why is it so difficult to just take a bit of time and just read what someone else has written?
Do I really demand too much when I just ask for / beg that members just read before they are replying?

Sorry again, but I have been just frustrated about that behaviour in general in the last days.
I respect Drew very much.

Sorry again, my English is very bad, I am not a native speaker.

Threads like this wander. This thread has wandered a lot. So it is sometimes difficult to read with continuity. I seem to have offended Henning yesterday for exactly that reason, and was subjected to the same snark... hence a bit of sensitivity on my part too. No problem; we all can get frustrated. :smile:

Your English is fine. I was poking... being snarky too. We all know what you meant. Sorry.

Bingo. You have not in fact described any specific methodolgy behind your conclusion. And just how much actual printing have you done with these fllms that does not involve some kind of intervening scan and software complication, which might be erroneous confused with film performance itself? I apologize if I mis-read your distinction between grain and perceived acutance (itself debatable, since it would have to be compared at equal contrast levels, which these films are not). But you in turn have confused my statement that Ektachrome is cooler than Provia with Astia instead, which has roughly the same color temp balance as Provia, around 5200K.

But NO, Astia was never tweaked or extra warmed for skintones per se, like most color neg films, but was less contrasty and had the best overall color balance of any chrome film ever, so was MARKETED for various critical studio applications relative to that fact, including portraiture. In fact, it's the same product line which they sold as their critical CDU duplicating film when tungsten-balanced. I used the final version of daylight Astia 100F itself to attain the highest quality Dupes ever in my experience, and simply rebalanced it with a very precise RGB additive colorhead. Astia had the same engineered Daylight color balance as the Provia and Velvia lines. Dinstinctly tungsten-balanced Fujichromes were made, but not to my knowledge ever a warmed daylight chrome, like the Kodak X version of Ektachrome.

I have shot and darkroom printed all of these films, every generation of Provia, Astia, CDU, in 8x10 film format (except for duplicating films, which were of course used in the lab only), along with their Kodak equivalents, including each generation of Ektachrome all the way from classic old Ektachrome 64 up to E100, either in 4X5 or 8x10. The current E100 I shot for analytic purposes only, and then repeated that a year later to get an idea of batch consistenty - all spot on (it was correct 5500K color temp exactly, true box speed, and had precisely matching hues batch to batch). Every step of this was precisely monitored : color temp meters, true 18% neutral gray reference (industrial spectrophometer confirmed - accurate gray cards and discs are surprisingly uncommon), pristine MacBeth Color Checker Chart, transmission densitometer readings, true 5000K CRI 98 pro light box (also something rare), etc etc.

Personal taste is a different kind of variable. I don't shoot chromes at all any more, having moved along to mainly Ektar color neg film in all formats, 35mm clear up to 8X10.

My apologies if anything has been misunderstood due to issues with English. I can only respond to what seems to have been said. Nor do I want to make a mountain out of a molehill, for those who have already found ways to make predictable exposures with their favorite films.

But the thread itself might not have wandered as far as some claim. I point these things out not for sake of an academic debate over discontinued films, but due to the fact of variability in both color response and latitude of all present choices of color film, and why one style of alleged metering does not in fact fit every foot, even within the relatively limited scope of chrome films themselves. If the moderator himself finds this excessively off topic, he is perfectly welcome to put on his itchy horsehair wig and condemn it to a different jail compartment.

I had quite a lot of stress recently so my nerves are probably a bit thin at the moment.........

That's precisely why I said that. Besides, you Canadians are not supposed to get hot-headed like we Americans to the south, unless it's over a hokey game. I have seen that excellent demographic educational documentary, Canadian Bacon, concerning such distinctions,
where John Candy explained it all.

Of course we're hot headed, we wear toques. Otherwise our ears would freeze.

Well, you're apparently cool-headed enough to overlook my sarcastic spelling of hockey as "hokey". Here on the Calif. Coast it's not cold enough for ice; but the roads are plenty slippery enough at the moment. Our version of the sport uses full-sized cars rather than hockey pucks.

I think I'm going to have to pull my court robes out of storage while acting as moderator here!
There is no way though that you are going to get me to put on the wing collar shirts or court tabs!
And as for the vest - sadly, that which fit me closely in my early 30s won't do the job now!
