Hi Emilio,

I know Ilfochrome distribution is still chaotic in Italy,
unfortunately, I don't know who is the official distributor.
If you're close to Switzerland, then you can order here from any shop
(provided they want to). If not, try to go through mail-order or
websites that sell it.
There should be some in Europe (Germany or France):

Just a few addresses quickly found via Google, you may find cheaper
prices in searching better than I did.
Ordering from the US may be problematic due to the air restrictions for
chemicals and shipment cost may be prohibitive. You can check with big
shops like B&H (http://www.bhphotovideo.com).
I prefer the CLM.1K surface which has the typical high-gloss surface
and a medium contrast usable with moderate burn and dodge.
Note there is a new chemicals kit P3.5 which is a 5 liters kit splitted
in 1-liter internal packages. P-30 kits now means old chemicals ...

Regarding the V35, it's a fine enlarger for Ilfochrome, but check it is
in good shape with the genuine Focotar lens. I see regularly strange
things on sale on eBay ...
Its only drawback is its limitation to the 35mm format.

Un salutone,

No, it isn't, and yes, it is.

No problem, we all started one day ...

I suppose you're talking B/W ?
Basically, there are an inversion and re-development additional steps.
I have a page on B/W slides that describes the general idea:
http://www.bonavolta.ch/hobby/en/photo/slidesbw.htm

One difficulty with positive slides is that they have a pretty high
contrast.
An usual B/W negative is pretty low in contrast, so the relative paper
to print on should have a higher contrast to compensate.
Your positive being high in contrast, using a paper having a high
contrast too may give an excessive resulting contrast.
To reduce the general contrast, you must use a very soft developer with
low grades. Maybe it is enough to obtain a correct result. I can't tell
you for sure as I've never tried it.

Positive papers like Ilfochrome and their relative process have a
natural low contrast to compensate the high contrast in the slide. When
you hear that Ilfochrome gives to contrasty prints, it is the
combination of the slide + the print that is still to contrasty.

R-3 is a color positive process for prints that is (well, was)
concurrent to Ilfochrome and meant to print color slides on paper.
Contrary to Ilfochrome, it was a chromogenic process where the dyes
were build up during the process, like in classic negative color paper
(RA-4 process).
Ilfochrome does contain all the dyes in the manufactured paper, the
process selectively bleaches the "excessive" colors.
I think (but maybe I'm wrong) all manufacturers have stopped their
production of R-3 papers and chemicals.

It's the same in broad strokes, but the details differ. One important
difference is that increasing exposure makes a print from a negative
darker, whereas it makes a print from a positive lighter. (Assuming you're
processing to get a normal print, not a reverse-image print.) If you're
talking about color prints, the effects of the filters will be reversed,
too. For instance, increasing cyan filtration when making a color print
from a negative makes the print more red (less cyan), but when making a
print from a slide, increasing cyan filtration makes the print less red
(more cyan).

Don't worry too much about R-3; the paper and chemicals are no longer
being manufactured, AFAIK. If you stumble across a stash of them, and if
it's all still in date, you might be interested in buying it; but you're
unlikely to find the stuff new in stores. I wouldn't recommend investing
time in learning about R-3 unless it's just to satisfy your curiosity or
if you find a bunch of R-3 supplies cheap. For making color prints from
color slides, the only official process left is Ilfochrome (formerly known
as Cibachrome).

FWIW, although Ilfochrome is the only remaining "official" process for
making prints from color slides, it's possible to make color prints from
slides using conventional RA-4 paper. The process is to expose the paper,
develop it in a conventional *B&W* developer (such as Dektol), put it in a
stop bath, rinse the print, expose the print to light to fog it, and then
proceed with the usual RA-4 process. The result isn't likely to match an
Ilfochrome (or R-3, if you have some R-3 paper and chemicals) print for
color accuracy and contrast, but you might want to play with the process.
The print is likely to be high in contrast and some of the colors may be
odd. The effect can be interesting for some shots.
