[APML] Fujichrome Velvia 100F

[Wei-Hao Wang <astrophoto@gmail.com>]

Hi,

While the deep sky performance of Kodak E100G is still unclear, there is some 
good news for people who like fine grain color slides.  A friend of
mine in Taiwan,
C.-J. Lu, took some very nice pictures using Fuji Velvia 100F.  Here are two 
examples Mr. Lu provided.

1. Whoke-sky Milky Way:

Taken with Velvia 100F +2 push, Pentax 67 35mm/F4.5 fisheye at F4.5, and a 
home made 4x5 camera.  Exposure time is 90 minutes.

2. North America Nebula:
http://www.ifa.hawaii.edu/~wang/misc/940714_NGC7000.jpg
Taken with Velvia 100F +2 push, Pentax 125SDP refractor at F6.4, and the same 
home made 4x5 camera.  Exposure time is 90 minutes.

According to Mr. Lu, these JPG images closely represent how the slides look on 
a light box.  These images should be good references for you to
evaluate the deep
sky performance of Velvia 100F.  From these images, it is clear that
Velvia 100F
has excellent H-alpha sensitivity and very good reciprocity property. 
The overall red
looking of the images may be because of the light-polluted sky in
Taiwan, or may
have something to do with the film itself.  Since the yellow color of
the summer
Milky Way appears correctly, the green sensitivity of Velvia 100F
should be also
good.  The only thing unclear is its blue response.  We need to see more images.

In addition, Velvia 100 had been introduced to US this month.  It
should be as good
as Velvia 100, according to the data sheet.

Still shooting slides?  Give Velvia 100/100F a try.

Cheers,
Wei-Hao
