Hi Michael,

Thanks for the comments. You mentioned Elite Chrome 200 as having a better
tonal range than the 400f and I don't doubt you for a second but will the
tonal range hold up at +1 ?

I'm still up in the air on the coming eclipse. I shot the last one on 400f
and the tones were pretty compressed. You can see it he

Then again, if seeing is so-so and taking into account a big reduction in
photons for the eclipse, ISO 400 should help a lot, and as you metioned,
shutter vibration will be less of an issue. Guess I better get busy and
shoot some Elite Chrome at +1 before the eclipse so I can get me a quick (I
hope) learnign curve.

Thanks again and take care,

JAS

Interesting to note the differences on the two films. First, the grain
is
more apparent on the 400f, but I also noticed the tonal range is
shortened
as well.

Right; high-speed films tend to be like that. Elite Chrome 200 less than
most... you might try it.

On the 400f's behalf, being able to shoot at 1/500th of a second
makes for consistently sharper pictures - free of most atmospheric
turbulence.

More to the point, it also "stops" the vibration from your camera's
shutter.

Nice!
