Various Speed with E6 ? Rollei Vario Chrome

[trendland]

Hallo everybody !
As far as I know you should expose E6
films most correct as possible.
But it may also be that I am not right due to this fact?
That should be very bad in concern to several years with this practice...?
Comming to film tolerances with color
and bw - there is an individual joice of
E.I. as we all might know.
But with E6 you will have an exposure tolerance of just 1/3 stop.
Am I right - or am I right with this ?
Suddenly Rollei have the idea to come
with a "new" E6 film with "variable speed" it is their new Rollei Vario Chrome ( ISO 200 - ISO 400 )
And here it is :

Well - the can looks realy nice to me.....but what is about this emulsion?
Rollei gives also an example to show the speed variation like here :

This should be a little joke of Rollei - shouln't it ?

What do you think about this ?

with regards

The central shot looks correctly exposed. The top and bottom look typical of about half-to-one-stop over- and under-exposure, as they might on most slide films.

Correct exposure is always in the eye of the beholder, it's entirely up to you, the viewer and the subject matter, which exposure is correct. Until a few decades ago the eye of the viewer was always me by a projected image, but this hasn't been the case in recent years where scanning took over. Suddenly people became more concerned about blown out highlights than bright projections, and the "correct" EI moved up.

Rollei took advantage of this fact by labeling their film with a more attractive box speed.

Yes - Rudeofus that is indeed a fact you mentioned in concert to scan slides - I have supposed it meanwile as a part of Rollei's intention to
"rate" this emulsion.
But it is a kind of low level logic from Rollei. The example from above shows definitively an exposure series everyone
who is in concern to E6 within 3 month is
familiar with.
The corect exposure with E6 is sometimes, wich you are referring, in regard to the actual light situation.
Messurements in complicate situations needs often corrections - as we all know.

And with E6 the correct exposure from best messurement basis is not 100% the best (sometimes).
Often the "incorrect" exposure of + - 1/3
stop is fine.
Sometimes an overexposure of 2/3 stops
is indeed an overexposure but it is also the best exposure to the motive (caused from failed messurement -1/3 stop) in addition the picture has a fabulous look
+ 1/3 stop over.
This we should all new as exposure series with E6 in 1/3 stop steps and 2/3 stop steps.The last is often to much with slide film.
But very new is in the concern to Rollei
that we have the first E6 film with exposure tollerance.
Notice : WITHOUT development correction. (Rollei stated : ISO 200 - 400
with normal E6 standard process).
And this should be a joke to me...!

The argumentation of you as an possible
intention from Rollei is indeed clever !
I follow them a bit before (the optimization in regard of scan worflow - as "various speed ")
But if we are just looking behind - it is nonsense - isn't it.
BECAUSE without darkroom work / slide projection - by just scanning films ?
YOU INDEED NEED NO E6 FILM ...
Best results are often given from c41 films.

The next question is to the film...
"What kind of NEW FILM do we see here"

In some forums you can read it is scratch
film from ferrania - comming from first emulsion test with FERANIACHROME?
Film with characteristics Ferrania don't
trust to sell - but Rollei will do this?

Well - let me short say : This is indeed
an other kind of nonsense - very evil nonsence of cause.

But how can Rollei belive this is clever?

To bring out an E6 film with revolutionary
properties (exposure tollerance ISO 100
- ISO 200) without telling us what is this stuff and where is it from ?

That is not very clever - sorry ?

Yes I would agree with you - it looks like
min. a half stop over- / and a half stop
underexposed. The mid exposure looks fine.
But notice railwayman3 this is advertising material to show the
"exposure tollerance" of Rollei Variochrome.........
to me a simple joke - sorry.
I have tons of such film stripes from the past.
More "Various Speed" as from Rollei I
noticed with Kodak EPR with very nice
colors decades ago.
Should we ask Kodak : " Hey dear fellows
wy didn't you tell us you have designed the very first E6 with various speed long before Rollei bring out this stuff ISO 50 - ISO 100 / recomanded box speed ISO 64....... (Kodak EPR)

I know the possible answer of Kodak.

The very first variable speed slide film came out years before EPR ?
Realy. ...? 1935 Kodachrome .....

Various speed ISO 5 - ISO 15 /
recomanded box speed ISO 10... !

PS : Incredible Nonsense (The Marketings Methods of Rollei at this time)

Does anybody think different ?

I appreciate what you're saying, and it's not unusual, as you say, to find that we get more pleasing results (for us) by an adjustment to the exposure from that based on the ISO speed quoted by the manufacturer (which they arrived at by their standard lab tests).

OTOH, Rollei appear be to implying that their film can be exposed at any speed within the quoted range with correct results, which is just not possible for an E6 film (unless you make adjustments in the processing, as with the short-lived Ektachrome designed for push processing. But that was marketed with the technical information for this to be done, not just as a film that you could expose at any speed regardless).

 

[Rudeofus]

E6 film has very different color rendition compared to C-41 film, therefore they always have their place regardless of whether we have a projector or not. As soon as one starts scanning slide film, optimal exposure can be quite different from labeled box speed. Whereas C-41 film allows for huge overexposure and still yields good detail, E-6 film doesn't. The situation is quite similar to modern digital camera sensors, where a stop of underexposure doesn't hurt shadow noise but preserves highlights.

But let's stay realistic: Rollei didn't do this to do a favor to people with hybrid work flow. They did this so they could put a higher sensitivity number on their boxes. They peddle some ISO 320 film and are now suddenly able to sell it as ISO 200-400 film, hoping that casual shoppers just notice the 400 number, hoping they can use it to replace now missing Provia 400X. The discussion reminds me of all these endless debates about Delta 3200 ...

 

[trendland]

Quite right, Rudeofus : "They peddle some ISO 320 film.......and sell it as ISO
200 - 400 film."
This will bring us to the next question :
Sure it is no "New" emulsion (that would
blame Kodak in an extraordinary way - by the time)
And as we all might now : Rollei has got no bizarre secret laboratories in Area 51 for design and production of secret E6 emulsions......
So - what kind of film do they assemble
in their nice canisters ?
Does anybody remember ISO 320 E6 emulsions produced after 2007 ?
I am just remembering the ISO320 variant
of Kodak's EPY...
Sorry but I forget the code - it was just
Ektachrome Thungsten - by the time the
very very first Kodak of 14 E6 produced
emulsions wich was discontinued.
That should never be our candidate here in case of Rollei"s origion.
I just remember Fuji Provia 400x was sold out and discontinued - meanwile
Rollei had an offer to this film with
high priced limitation.
That could be Rollei's origion.
Nice idea .......but we can't know because Rollei don't want to tell us.

[trendland]

By the time : Does anybody tryed this film
meanwile ?
I am sorry to say but it seams so that I am much much too stingy for bying this film.
And Rollei won't give it to me for less after I excoriate it a bit. .......

Perhaps I did it a little to much - perhaps
it is not the worst E6 ......?

I just remember some 80th slide films
from svema wich could be more worst.

Its not the old Agfa Aviphot Chrome 200 which can really be exposed between 200 and 400(developping time must then increased by 3min)
here are the rumors about a Kodak-film Surplus

Oh ......I did not know this - thanks for this information 3dreal.
.......and sorry for delay.
