Some really nice pics there John,
my favourites have to be
Chin Turret, Lonely Tulip and Spring Mill in Summer.
Thanks . . .
I wish the weather had been better for the B-17 and B-24 shots. The planes
were here for 3 days during high heat and humidity with "heat haze" the
entire time; no clear blue sky. :-( Same is applicable to the "Spring
Mill" shot and need to go there again next year, well before sunrise about
mid-Spring with cooler "clear sky" weather.
As Ive visited your website John, I notice you give the Kodak Elite CHROME
(Standard and Extracolour) a bit of a wrap. So do I, I think it is great
stuff and extremely well priced. Picked up some in oz today actually at
Kmart for AUD$8.89!!!!!!!!! BARGAIN.
I've used Elitechrome 100 in the past, and two rolls (maybe three) of
Elitechrome 100 Extra Color. I haven't used either in some time. Film is
very much a personal preference. The two ISO 100 Elitechrome's are very
fine grained with Kodak's "tabular grain" technology. Kodachrome and Fuji
Provia 100F have greater color accuracy. Saturation is about the same
among the three, but Elitechrome (100/200/400) colors are brighter compared
to some of the deeper colors I get from Kodachrome (which also has slightly
higher contrast).
After a few rolls of Elitechrome Extra Color I quit using it. It had far
more saturation than I wanted, at great expense to color accuracy. Don't
have people in the foreground with it! The clincher was a shot of a red
barn. The red color was nowhere near the actual color of the barn, and the
super heavy saturation "blew out" some of the detail level in the barn
siding. Some want the saturation and color accuracy isn't as important to
them. Most high saturation landscape shooters still seem to prefer Fuji's
Velvia for its green response though.
Ive also heard a lot about Fuji Provia's 'F' range. I noticed it on your
picture Loney Tulip. Looks great.
What are your's and anyone elses thoughts on Provia F? From what I see,
it's a pretty high performer. Though I still think Kodak's Elite CHROME
Select Series is great too.
Provia 100F is the closest E-6 I've found to Kdoachrome with color
accuracy, saturation, contrast and detail level. Even so, Kodachrome still
has a unique appearance with edge definition. This affects acuity of the
image and helps close the gap with Provia's slightly finer grain. Much
like using an "unsharp mask" does when processing digital scans for web (or
other) use.
*** What film you use depends on what you want for the image(s) ***
Some technobabble about E-6 versus K-14 film emulsions:
The reason Kodachrome has greater edge definition is a fundamental
difference between E-6 and K-14 emulsions. E-6 ("Ektachrome") films have
the dye linkers in the emulsion; K-14 ("Kodachrome") does not. They must
be added during the K-14 processing. The lack of dye linkers makes the
Kodachrome emulsion much thinner. This doesn't affect ray paths of light
perpendicular to the film plane, but it does the oblique ones that travel
through the emulsion at an angle. The thicker the emulsion, and the more
oblique the ray path, the more it cuts across the emulsion and the more
edge definition is lost. One must have excellent camera optics with high
resolution, and carefully focus the camera to see the effect:
C-41, E-6 and K-14 films have three emulsions (Fuji has added a fourth to
some of its films):

Want the highest possible edge definition? Use a *slow* single-layer B/W
film with the thinnest possible emulsion. Of course, other characteristics
of the film will likely be important, possibly more so. The decision is
very often a tradeoff about what's more important. The reasons for using
Sensia 400 for the night street shots was film speed and it's finer grained
than Elitechrome 400. I would have preferred Provia 400, but couldn't get
a pro film in time, so I settled for Fuji's consumer equivalent.
