Avoiding Aventurine Aviphot

"Aventurine glass" is what glassmakers in Venice used to call glass that had gone yellow because of a misadventure. So "Aventurine film" would be film that has gone yellow when it was not intended to.

Aviphot is a colour reversal film sold by Agfa for aerial photography. It is purchased from Agfa in bulk by companies who cut it to smaller sizes and sell it as 35mm, 120 and movie film. (Wittnerchrome 200D, Rolleichrome CR200, Lomochrome X-Pro 200, Crossbird, maybe ReraChrome 127 too.) It is based on Agfa's RSX II 200 film, but is on a polyester base. Some users say this a wonderful film, but many others find it shows a strong yellow cast.

I have just posted about this yellowing in the thread titled "Color correction for Rollei Digibase CR200?" and I am starting this thread specifically to discuss ways to avoid that yellowing. So I have given it the title "Avoiding Aventurine Aviphot".

My post suggested: 1/ make sure the film has been stored well, 2/ load it in low light, 3/ be aware that in warm sunlight it gives very yellow colours, 4/ process it very soon after exposure. In other words, understand the film, and treat it like a professional film (store cold, shoot the whole roll in one session, process promptly). Does anyone have comments to add, please?

Ive just stumbled across this thread after going back on my posts in the other thread on this matter.
I got into argument in the Ferrania Thread with another shooter that claims that this is the intended nature of this film stock for aerial photography.

I can verify this is not the case, as any UV compensation at hi altitudes can be avoided with filters on the camera itself.
From what I understand, this film is simply Agfa RSX-II on a polyester base.

Here are some of my shots taken on this film. None have showed any yellowing.

I absolutely agree - one of the many tests I carried out to try to understand the yellowing was to take some photographs of snow while on a flight that went high over Greenland. I used Rollei CR200 and Ektachrome 100G. The Rollei gave yellow results as ever - there was no sign that it was compensating for UV (and in any case, RSX-II has a UV filter layer built into the film itself). The E100G gave nicely white snow. The yellow was _not_ an attempt at compensation for high altitude.

Thank you, wonderful, and these show how good Aviphot can be, especially that sold as Wittnerchrome, if it is treated well.

Yes I have, yust posted in your older treat.

Sorry for not reading this nee treat before.

Ok - problems with aviophot it cr200 stuff.

At first : This film is not fine grained -
surely not (ISO 200) to much vor a
slide film I would say.

Secondly : You have to test if you have some of the "bad CR 200" ( look of the older post - I described it there )
this make sense if you own a large amound of roĺls
bought at the same time - otherwise it
makes not so much sense (when you have only one it two rolls)

Finaly : Good CR 200 Stuff does have
correct colors some like the nearly old
fashioned color style of this emulsion.
I would not say it is more yellow than
Ektachrome 100 VS but it is very grainy.

Colors are saturated well.


For "bad CR 200" I would advice you to
make some tests with different wratten
filters.

You will need a "deep blue" filter.

Have also a look in "Lee filters"
they have a lot of color effect filtern
in all variations with blue.

Some of theese stuff you will need.

But an absolute corect color corection
with "bad CR200" seams to be quite complicate to me.

So you have to try your best.Lots of possibilitys - bon chance!


with regards

Either way, all the rolls ive shot have been great.

I dont mind the grain, but would be nice if it was less. Other than this, it is a very comparable film to Kodachrome, i love its reds.

I bought five rolls some years ago and tried the first one in E6. Looked like crap, way too yellow for me. I didn't mind the grain though. I cross processed the latters four.

These were two of my recent shots.
They look perfect to me.

Yes i believe so, as many films also do, it was just that some claimed this was the reason for the yellowing.

By the time Berri I remember one post of you as you described you situation in Italy and your plan to go to GB.
What is the todays status? Have you made decisions?
A colleague of me was asked for a job
in Germany he is Steadycam Operator but his performance isn't the best nowadays (age,constitution,experience)
I am with him to this job (TV Comercial),
and he still need a new assistence.
(Fokus pulling ) because the last job he made was not the best ...
The typical situation for new young guys to get in a position : motivated,creative expirenced, ready for action at any time.
It was a little like you described I remebered this as one of the produktion crew anounced : "Ok so we need a new assistence for this job. Anybody is needed imediately. "But there are No Anybodys with experience imediately" I would like to say.
They now asked a technician if he would like to make the job ? He got it.
Last Info I have : What is the money for this job ? Answer : Nothing - the producer has no money in addition to pay this guy ( he has - but he will not pay) !!!!
So - that is the reality in 2017 ?????

Not so good I would say !

with regard

PS : In GB it should be nearly the same situation I fear.
