Portra marketing blurb boasts that it's optimised for scanning. Optimised in what way? Is is the grain pattern? The colours?

I've only scanned one roll of Portra 160 and the colour correcting was a nightmare. But I'm fairly sure I underdeveloped the roll which may have been the root of the problem.

Good question! My guess is the less shoulder and/ or a higher Dmax, or at least a more pleasing result when more density(exposure) on the negative is used, i,e. something to do with shoulder

It could very well relate to factors that barely affect optical printing.
Things like grain aliasing, flatness of film, response to LED light sources.

I'm curious about that too.

Does Kodak have someone on Photrio to field questions? Film Ferrania does and it's been very interesting taking a peek into their projects.

It sounds like Portra was designed to square the circle of good optical printing and scanning if the marketing blurb is to be believed. I take it this is the Kodak marketing blurb? If so, did they say this from the inception of the latest Portra or is this a new piece of marketing-speak. Does the marketing-speak state that this "made for scanning " is a design aim anywhere?

Does Portra in fact precede the scanning era?

Yes - at least it precedes the era when almost all commercial processing included a scanning step.
Kodak has been talking about "scan-ability" for quite a while.
Films have always been "tweaked" as the processing technology advanced.
The "optimized for scanning" may merely mean that Kodak tried out the film in a number of different commercial scanning options, and then adjusted the film slightly to make sure it worked easily in the most common lab scanners.
I expect all Kodak 35mm films were well matched to the Kodak Pakon scanners and software when those machines were current.

In the Press release when "new" Portra 400 was launched (2008) Kodak said on this specific point:
Outstanding scanning results
With finer grain and an emulsion overcoat specially designed for scanners, Portra 400 films reproduce beautifully, with either optical or digital output.

So the two optimisations were finer grain and an overcoat.
Of course Kodak archives don't have the releases, not that I can find anyway, so my source:

Interestingly though a previous press release of the prior generation made the same claim on the "older" Portra family:

No, they don't.

If any other manufacturers do I'd appreciate a heads up. I know PE is here, and Ferrania, and once upon a time someone from Ilford but I don't see that now. (sorry for the thread hijack)

Ilford used to be here on a near daily basis. Those were good times. Now, not so much.

I have shot over 700+ sheet of Portra 4x5, and hundreds of 120 and 135mm rolls.

Yes, they scan beautifully. This is Portra 160 in 120 F2 at 1/30. I didn't get the memo that you are not suppose to shoot that low speed on an SLR (Hasselblad 203FE) ~_o

Did labs for consumer prints still use optical enlargement in 1998??

Yes. The ones I used. At the time Samys and there was a local optical only shop near me that recently shut down.

They did where I am in Australia. A lot of pro-level labs (which also provided consumer film processing) stopped optical printing from 2000 to 2003.

Prof Pixel is ex-Kodak, and probably has a fair amount of insight into scanning.

One more question regarding this thread. Did Kodak introduce this film because most labs that print color negs have phased out optical printing? They choose instead to scan the negative then print digitally rather than printing optically to photographic paper?

No.
Portra was/is the natural evolution from Vericolour.
Portra arrived in 1998. The scan and print from scan workflow may very well have been in the plans at that time, and may have been in some labs, but it certainly wasn't everywhere.

It's also optimized for optical enlargement ! These newer Kodak films (including Ektar) have a subtle overcoating which presumably allows more efficient scanning. I noticed how, on sheet films, this seems to minimize Newton's rings much like the retouching surface on certain older b&w sheet films, but is completely different in other ways. I print current Kodak roll films too, but can't comment on other aspects of this question.

Is there a custom profile from Kodak available for specifically scanning Portra?
Or a profile that is customised for Portra by the user/lab?

I know what you mean as depending on your scanner software it can go all over the place but if you want to hit neutral grey just shoot a frame with a colour chart in the image and the hit the neutral grey and it works great!

I've only scanned one roll of Portra 160 and the colour correcting was a nightmare. But I'm fairly sure I underdeveloped the roll which may have been the root of the problem.
