Velvia 100 compensation

Hi Folks,

Just bought a bunch of Velvia 100 and am headed to the North Rim of the Big
Ditch to shoot it.

I used to shoot Velvia 50 at around ASA 40 in the SW. Should I compensate
for Velvia 100 and shoot it at around 80? Or does it meter true-to-form?

Best,

Chuck

Chuck,

I did some basic testing and convinced myself that it was accurate at
100. The few magazine review articles that I've read on Velvia 100 also
confirmed the same. I now use it instead of the 50 (which I definitely
had to expose at 40), and I've been very happy with the results so far.
The only down side it the cost premium for the 100.

In a case like this you also have the option of doing a "snip test".
This may seem like a very "amateur" thing to do to some of those who have a
very empirical approach to their photography, but I've worked on commercial
projects where, no matter how pinned down the variables were, a snip test was
routinely done to ensure that everything was going to come out right.
Basically, this means running a few frames "snipped" off a roll of 35mm through
the processor to see if it is, in fact, spot-on or if an adjustment in
processing would help to produce the optimum results. In the case of medium
format you may have them snip off some film or just shoot a whole roll of
typical subjects that you can afford to sacrifice (it may not be a sacrifice -
it will probably still be usable). For LF it's easier...just run one or a
couple of sheets through. The cost of doing this and any additional costs that
you may incur for adjusted processing is a small price to pay for the
"insurance". Review the results and ask the lab to make any adjustments that
you feel will produce your desired result. I've had the advantage of doing
this with both Ross-Ehlert and Gamma labs here in Chicago and it has always
worked.
Again, this may seem a somewhat slipshod way of working to some, but think
about it...when the expense of setting up a shot or a session or the expense of
traveling to a location is the big cost of the shoot, it can be a very valid
way of working,

Snip tests are commonly done by professional photographers on commercial
assignments. There is nothing amateurish about them at all.

Most of my equipment is new, and meters correctly. My lenses are also
new
or relatively new and spot-on. I don't have time to test.

It was relatively well-accepted that Velvia needed to be slightly
overexposed. My question is regarding the new Velvia 100. What have
folks
found?


I have found that using untested film on an odyssey is a foolish thing to
do. Laughably so.

Do you feel lucky? No test shots is a real risky deal. BTW, I would take
some Kodak E-100G. Velvia's main problem is color fidelity in thedeep
red/purple spectrum, where it stinks.
