Kodachrome
films
(I use the present tense - films are still available summer 2006)
Kodachrome
is very contrasty, but with relatively low colour saturation.
Highlights easily "blow", while shadows block up.
It has a very short "straight line" section
of its characteristic curve, at best a couple of stops.
This
means landscapes can have thin, overexposed skies, and heavy, dark
foregrounds.
The
other big problem with Kodachrome is it's tendency towards a "crossed
curve" -
the highlights go pinky magenta while the shadows
go greeney cyan.
This doesn't look so bad on projection, your
eye can compensate to some extent, but plays havoc with printing -
trying to correct colour in two opposite directions!
Unlike
just about all other slide films, Kodachrome has it's own non
E6 processing.
This is unfortunately by no means consistent
- I have seen some really whacky colour...as
in deep pink snow, particularly on Kodachrome 200.
Kodachrome
64 is sharp, and fine grained.
Kodachrome 200 is a very grainy film.
Kodachrome lasts well, and I have slides in good condition from the
1960's
Kodachrome
is very challenging to print, but I do understand many photographers
have a great affection for it.
It has a certain "something" that other films lack.
A "real" look that suits certain subjects.
Kodak
E6 films
Traditionally
Kodak's E6 films have been a bit on the subdued side, but Extra Color
100,
and Professional Ektachrome E100VS (both!) claim to be the highest
saturation 100 ISO's on the market.
E100VS certainly has plenty of colour...
But - flesh tones tend towards the hyper, red
flowers can appear as blank red disks.
Still,
this is all just a printer's view of things - see what
have to say about their E6 films.
Fuji
Provia
has a very smooth characteristic curve, with a long usable range of
exposure.
The blues and greens of Provia are excellent, flesh tones controlled...
Having shot some comparisons of Provia and Sensia, I would hesitate
to recommend Sensia.
While still a very useful film, it is softer than Provia, lower saturation,
and has less "body".
Velvia
50 was a splendid film, very saturated, also very sharp.
The only downside was contrast, it needed very careful exposure.
For
my money the new 100 ISO Velvia is not quite as good, but it's still
probably the "strongest" colour slide film available
It
has a very sort useful subject range, similar to Kodachrome's, a
couple of stops or so.
I would not recommend it for portraits unless you can really control
the lighting ratio!
Fuji's
low contrast offering is Astia.
I'm not that impressed by Astia- it tends print a bit weedy and flat.
I guess it has it's uses for ultra-contrasty situations.
I wouldn't
recommend any transparency film for weddings, or indeed any portrait
work
(use colour neg!)....but
if you must, Astia is probably the best choice.
I haven't
done any serious testing of Astia, but I often see rather light
Astia slides -
I wonder if it might be slightly Underrated?
Around
90% of the transparencies I am sent are Fuji of one sort or another.
Here's
what
have to say.

Agfa
It was
very sad to see one of the big three colour film producers go into
liquidation last year.
While I was never a great fan of Agfa slide films, their colour neg
range was great, and Scala a unique and well loved film by many of
my customers.
I've
retained the notes below, as people still send in Agfa slides - there
must be a lot around!
Agfa
colour slide films were odd. Not like Kodachrome, no badly crossed
curves, but the colour was well, weird.
Nothing like as saturated as Fuji Provia, let alone Velvia,
but very strange to print.
I usually
print Agfa trannie with a lot of yellow/red, filter wise, but sometimes
it seemed to go completely the other way. The colours tending towards
a rather flat, crude feel.
Shadows
didn't block up as badly as Kodachrome, but highlights did easily
blow out.
Agfa colour slide films were not the finest grained...
Having
said all that, Agfa's colour neg films were superb!
Particularly Ultra 100 - if you wanted mega saturation...
I get
sent quite a lot of Scala, Agfa's black and white slide film.
It can look really good on Ciba, once I've achieved a neutral grey.
It was
a very contrasty film, so expect results on Scala to be dramatic rather
than subtle!

Processing
If you're not using process paid film, find a good E6 lab and stick
with them - different film processing lines make a surprising difference
to colour, sometimes more than which film is used !
Film
drying and handling is indifferent in some labs, to say the least:
is excellent, but not cheap....
