I am very touched that this picture has been
viewed more than 64,000 times since it was
selected as the POW, and the number of members
who take time to leave comments. When I first
put my portfolios on photo.net I only thought
it a quick way to share the images with my
teachers and friends. Never dreamed it to
reach 60k+ viewers, although I understand there
are many counts from repeated visitors.
I really love fall colors. The first school for
my graduate work in the States was UM-Duluth (in
the mid-80s), where the autumn is simply
fantastic. I finally finished my schools in
Pittsburgh and came to work in the San Francisco
Bay area in 1995, picked up the old photography
hobby two years later, when I was barely afford
to, the first time in my life. I did some B+W
works back when I was young. I went to New
England and Adirondacks of New York three times,
came back almost empty handed after endless
fights with traffic jams, tourists, babwires and
fences, phone and power lines and poles, and
private land and no trespassing signs. The
fences do make nice foreground and the white
churches are gorgeous against the color, but for
some reason I found it is not to my idea since
I want something more than the travel shots
and try to avoid man made objects in general.
Then I signed up a week long fall color
workshop with John and Barbara Gerlaches near
the Pictured Rocks National Lakeshore in early
October last year, which turned out to be my
most productive week. John and Barbara are
the finest instructors and the nicest people
one can ever meet in this world, with
complete knowledge of the region after living
there for many many (15+?) years. The
workshop that they offer every Fall is very
sensibly priced as well, which is a factor to
me at least. It even had a totally
unexpected guest to join the group, whose
name is John Show. We met many other pros in
the area, most of them share the same
experiences I had had in New England, and
believed the mid-north locations are better
for photographers. Here in upper peninsula
of Michigan almost all the lands and lakes
are part of the National Forest, and the
peak color of the year knocked every one's
sock off to say the very least, which lasted
for more than a week. A real photographer's
heaven where for the first time I run out my
film, about 70 120 rolls plus some 35mm.
Usually I carry twice as much as I thought I
may need. It may be true that the scene
like this is everywhere all over Canada at
the season, but I do not live in Canada
so that naturally I was over excited by the
nature's giving in Michigan.
Technically, it was a easy straight shot,
since the overcast weather condition. My
better shots of the trip were mostly from
my return visits to the places the group went
to in the week AFTER the workshop, since by
then I know where to return to. Also the
weather cooperated: it was mostly sunny
during the week, but turned to cloudy and
eventually snowed later that wiped out most
of the remaining leaves. The shot was taken
in the same birch and maple forest up on a
small hill where I also shot the D67-272,
"Fern and Maple in a Birch Forest", at
around 4:30pm, in the lucky late Saturday
afternoon when there was basically no
wind! With 6x7 medium format I loose two
stops of DOF in comparison to 35mm, so I
had to stop down the 135mm macro lens all
way to f/32, which is merely equivalent to
f/16 in 35mm. To me I need to keep
everything sharp for this kind of close ups.
The 81B warming filter was necessary in
such overcast days, and actually not quite
enough. The chrome still look too blue on
my light table, which is corrected with a
curve adjustment layer in Photoshop. A
81EF might be just right. The exposure
came naturally and easily from the
diffused lighting, metered with the Pentax
67II's AE prism in the matrix mode, with
the Velvia rated at ASA 40. I bracketed at
0.7, 1 and 1.5 seconds (Pentax can modify
the 67II to do half-stop speeds) since
Velvia is such a "nonlinear" film for
which a third exposure change makes a
lot differences that is not predictable,
even in such low contrast situations.
If I see something good through the view
finder I do not want to take the chance
of a single shot. Films is cheap but
time and travel are not as they often say.
If I were returning to the scene today I
would have packed more Provia than Velvia,
since I learned that the Velvia saturates
on red too early. David Muench shoots only
Velvia but many of his red rock country
pictures can be better if he were with
the E100VS, which shows considerably more
shades of details of reds and oranges
typical in his pictures. However, as
many pros found overall the Kodak has a
hot or unsettle tendency while Fuji tend
to put peace to the viewer's mind, even
under the loupe the details are almost
identical. The E100VS just can't convey
the tranquil and subtle refined feeling
the Fuji and the Japanese arts are good
at for these kind of forest shots, unless
we want to build tension of some sort.
On the transparency of this shot the
colors are really saturated and I think
I lose some details of subtle variations
of the red on the maple leaves. I
partially corrected that in Photoshop
with a level adjustment layer for the
selected reds. And the reason that for
many the image's color look muted is
from the fact that I further reduced
the color saturation before I converted
the image to the sRGB color space for
the web use. The S/H slider was at
-45 as I can remember. If I do not do
so all the reds would be pure and solid
on the web. I believe with a properly
calibrated monitor the color saturation
of the posted version is about right to
my eyes, beyond which I start to loose
details in saturated region. On a 20x24
enlargement of the shot I can see veins
of the leaves from 4 inches away.
As many found I am a perfectionist in
nature on the technical side, maybe also
partially from my training in science
(Physics). Many people tried the Pentax
67, and give up, saying that the images
are not sharp. I found it were true if
I used a lesser tripod, say, a Bogen
3021 which I did try. The shutter shock
problem of the P67 demands heavier
support, even with the mirror locked up.
The P67 is by some means a handicapped
system on which I can't fire at shutter
speed at 1/8 and 15/1, and for which I
found the Grizo 1548 absolutely
necessary even it costs a fortune that
offset the cost of the very cheap MF
system otherwise. However counting in
the $1k for the 1548 the system is
still inexpensive, and cheaper than
many of my friends 35mm outfits.
I also use a short aluminum center
column with the setup, on which I
drilled three holes across so that I
can stick through a philips screw
driver which I always carry, to hung
my 25lb (at least) backpack to further
weight down the tripod, as I found
nothing substitutes the physical weight
in damping out the P67 shutter vibration,
although the carbon fiber (or wood) legs
do absorb the vibrations much better
than the metal ones. I am a really a
sucker for image sharpness, since why
take the troubles to shot the MF
otherwise? I pick my keepers, both
the frames and the lenses, with a 22x
loupe, so that I can enlarge my 6x7cm
chromes to 24x30 digitally still with
details to be unveiled from inches away!
Many viewers thought the prints are from
4x5 originals, but after rented 4x5s
several times I found they conflict with
my available time since I have to keep
my full time job, as well as with my
limited budget. I think so far I have
found the right balance for my kinds of
photography with the Pentax 67 system.
I would also like to talk a bit on the
P67 lenses. I found considerate degrees
of variations of sharpness versus aperture
settings on different samples of the same
lens, with a tendency that the old ones
manufactured 10-20 years ago better than
the newly made, no matter how beat up
looking of the exteriors. This certainly
makes the eBay my heaven. I test each of
my acquisitions carefully with resolution
chart, and pick keepers, some of them
seems to perform against the known physics
laws of diffraction. This 135mm for this
shot is an example, as for some reason it
keeps almost all of its sharpness of f/11
at f/22, and degrades very little at f/32.
This is not the case with the other two
samples I have tested.
I almost always stop down all the way, or
to at least a stop more than the DOF scales
tell, since the DOF is the primary problem
of my MF efforts. I found that the
softness from diffractions can be very
effectively corrected by the unsharpen mask
filter in Photoshop, while the out of focus
elements will be always out of focus. In
my collection of P67 lenses, the 55mm f/4
is the other that keeps to be razor
sharpness all way down to its minimum f/22,
with both of the two samples I have had.
They are the sharpest lens I have ever seen
at all apertures from f/8 down. The same
is not true for my 45mm, 75mm, 90mm, and
105mm, all of them lose definition when
stopped down to the minimums. Recently I
added a 55-100mm zoom to my bag, after
inspected my friend's chromes shot with the
zoom, which closes down to f/32 at all the
focus lengths. Surprisingly I found the
zoom performs on the same level or even
better than my primes center to edge, with
minimal distortions and flares, and is
very sharp at f/32. This give me room to
modify my 55mm/f4: I took the rear sections
apart, and inserted spacers to make it to
have a built in (fixed) down tilt of about
one degree. This have been my lens for
near-far shot, since without the help from
the little tilt I could never really get
enough DOF even from the wide angle for
the 6x7 format at it minimum f/22, which
converts to a 28mm at f/11 in 35mm format.
Surging Cloud Falls at Sunrise

From the photographer: The sunrise of November 4, 2001
in Huangshan Mountains looked exactly this
colorful, with a lot of reds and yellows and magentas on the top, and cool lights down the
valley. I did not use filters to add color, and
there was no color added in Photoshop in which I
did a global color correction to remove the
blueness in the shadows by making the clouds puring into the valley neutral (plus some moderate burnings and doggings on a Softlight layer).
The color correction did fuether warm up the top to render it look maybe "artificial", but all the colors and the whole composition were natural and is on the original film - Velvia is famed to pick these warm tones. Perhaps I should have kept some of the shadow blueless to reduce such effects. It was a very special and spectacular sunrise. I shoot 16 rolls in a two hours window, including several all similar to this. The other images from the same session include the #8 and the #12 (the last one) of this portfolio; and the #4 of the portfolio "Huangshan Mountains II". Together they document the development of colors that very morning, from red-magenta before and at sunrise to yellows, whites, and blues after.
