WHEN SHOOTING COLOR NEGATIVE OR C-41 FILM, ERR ON THE SIDE OF OVEREXPOSING
THE FILM.
When you overexpose your film, you are exposing for the shadows, which
guarantees detail in the darkest parts of your image. Overexposing doesn’t
kill your highlights, though. It is almost impossible to have blown
highlights with color negative film.
This freaks digital shooters out, as you’ve been taught to err on the side
of underexposing your digital images. Underexposed film images look like
crap. Underexposing can introduce noticeable grain, strange color shifts,
and muddy blacks into your images.
That said, Kodak Portra film can be underexposed up to three stops. (It’s
the only color negative film that can be underexposed and deliver results
you won’t be embarrassed to show other people.)
HOW MUCH YOU OVEREXPOSE YOUR FILM IS A MATTER OF TASTE.
All Kodak films can be overexposed by half a stop without introducing more
yellow into the image. To do this, I meter with the bulb out and held
perpendicular to the ground. We’ll talk more about that later. If your
style involves crazy-heavy contrast and you’re willing to color-correct for
the yellow you’re introducing, overexpose your Portra by a stop or two.
Overexposing Fuji films introduces contrast and saturation to an image. With
Fuji film, overexpose by two to three stops in totally flat light. If your
subject is back-lit, overexpose by 1.5 to two stops. And if you’re shooting
in direct sunlight — so the sun is already providing heavy contrast —
overexpose by just one stop.
OVEREXPOSING SAVES ON RETOUCHING TIME, TOO. You’ll hide blemishes or large
pores on your portrait subject by overexposing an additional stop. Creamy,
creamy skin with minimal retouching is the result.
This is basically doing post-processing at the time of exposure — sneaky,
eh? Just saved you a few hours in Photoshop, per shoot, over the course of
your multi-decade career. You’re welcome. Make checks of gratitude payable

发帖数: 5682 | 5 From how to use a light meter....
OUR GOAL IS TO OVEREXPOSE OUR IMAGES. HOW MUCH WE OVEREXPOSE THEM DEPENDS ON
WHICH FILM STOCK WE’RE SHOOTING.
HOW TO METER FOR KODAK COLOR NEGATIVE FILMS AND FUJI 160C:
1. Set the ISO to the same ISO as your film. If we’re shooting Portra 400,
that’s 400. The ISO is in the name of the film.
2. Set the meter to take an Incident reading.
3. Make sure the meter’s bulb is in and that the light you are reading is
the same as the light falling on your subject. If your subject is in the
shade, your bulb should be in the shade. Subject in the sun? Get that bulb
into the sun!
4. Hold your meter parallel to the subject and perpendicular to the ground
as the meter faces you. Remember, 90 degrees is perpendicular to the ground.
5. Take a reading.
6. Set your camera to shoot what the meter reading just told you to shoot.
HOW TO METER FOR FUJI 400H AND 160S:
1. Set the ISO to the same ISO as your film. If we’re shooting 400H, that’
s 400. The ISO is in the name of the film.
2. Set the meter to take an Incident – NOT SPOT – reading.
3. Retract the meter’s bulb. When it is out, it’s metering 180 degrees. We
don’t want to meter 180 degrees, we want to meter for the shadows. With
the bulb retracted, we’re all set to overexpose our image by 1/2 to 2/3 of
a stop.
4. Hold the meter AWAY from the subject and 45 degrees to the ground.
Remember your basic geometry – 90 degrees is perpendicular to the ground, 0
degrees is parallel to the ground. You want 45 degrees.
5. Take a reading. That 45-degree reading you’re taking will overexpose by
another 2/3 of a stop. (So, 2/3 by retracting the bulb and 2/3 by holding at
45-degree angle — we’re talking overexposing by 1 1/3 stops. It’s a
perfect reading!)
6. Set your camera to shoot the f/stop that the meter reading just told you
to shoot. (More on that below.)
Boom! Perfectly exposed film! Where’s that Easy button? | a*f

发帖数: 5682 | 7 我觉得合格的数码化不会丧失太多胶片（尤其是负片）的色彩表现。

发帖数: 3928 | 8 这个over exposure 其实和另一种说法接近，就是胶片要对暗部曝光，对高光显影。
