1. What is the KODAK DIGITAL SHO Professional Plug-In?
The KODAK DIGITAL SHO Professional Plug-In is software that can automatically
adjust both the shadows and highlights so that more detail is visible.
The KODAK DIGITAL SHO Professional Plug-In allows the user to set the
threshold between shadow and highlight, and control how much the
shadows are lightened or the highlights are darkened independently. The
threshold preview shows visually which areas of the image are
considered shadows, and which are considered highlights for more
precise control. The professional version works with 16 bit images,
allowing you to make full use of raw format camera images or film
scans. The KODAK DIGITAL SHO Professional Plug-In is fully compatible with
ADOBE Photoshop actions, and can be run in batch mode. The KODAK DIGITAL SHO
Professional Plug-In works with 8 or 16 bit digital photographs from
any source, including film scanners, flatbed scanners, digital cameras,
CDs and the Internet. It is compatible with Adobe Photoshop and other
programs that support Photoshop plug-ins and is available on both
Windows and Macintosh platforms.

2. What is the difference between the
color saturation adjustment in the plug-ins and the color saturation
adjustment in my image editing application?
The color saturation adjustment slider in the KODAK DIGITAL SHO Professional plug-in adjusts the vividness of the colors
in proportion to the amount of adjustment applied to an area. The color
saturation adjustment in your image editing application adjusts the
saturation equally over the entire image. For example, using the Color
Saturation slider in the plug-in to reduce the saturation on an image
with the shadows lightened and no highlight adjustment, would reduce
the saturation in the deep shadow areas more than in the midtones, and
not affect the highlights at all.

3. Why does my image sometimes seem
to get noisier when I set the Shadow Detail slider to a high amount of
The noise was in the original image and wasn't
visible because the
shadows were so dark. The DIGITAL SHO plug-ins can only reveal detail
that is already in the image, and doesn't try to distinguish between
detail and noise. Applying DIGITAL GEM, DIGITAL GEM Professional, or
some other noise reduction, to the image before applying the DIGITAL
SHO plug-ins will help. If the image is very dark, you may get better
results by applying the DIGITAL SHO plug-in twice with a moderate
amount of shadow adjustment instead of applying the plug-ins once with
a high amount of adjustment.
4. How can I get the best results
from KODAK DIGITAL SHO Professional?
The KODAK DIGITAL SHO Professional plug-in works best on wide
dynamic range, low noise images with no overall color cast. To make
sure that your image has the widest dynamic range possible, don't apply
any contrast or brightness adjustments that may clip or compress the
range before applying KODAK DIGITAL SHO. If your image editing application
has the ability to view the image histogram, make sure that the
histogram fills the entire range available. An easy way to fill the
entire range without clipping in ADOBE Photoshop, is to set the clip
percentages in the Levels tool options to 0% and use the "Auto" button
to expand the range.
If the image is very noisy in the shadow areas,
apply KODAK DIGITAL GEM Professional, or some other noise
suppression to the shadows before applying KODAK DIGITAL SHO
Professional. If you aren't using on of the KODAK DIGITAL GEM plug-ins, be
careful not to apply too strong a noise suppression. Some types of
noise removal will also remove or blur detail in the shadows, and
KODAK DIGITAL SHO may reveal artifacts that can't be seen before the shadows
If the image has a slight color cast, the color cast
will be more noticeable after applying KODAK DIGITAL SHO. Applying KODAK DIGITAL
ROC Professional with the black and white clip set to 0% before running
KODAK DIGITAL SHO will usually take care of any color problems. If you don't
have KODAK DIGITAL ROC Professional, correct slight color casts with the
tools available in your image editing application. Most editors have a
"Levels" adjustment that you can use to adjust the input levels for
each channel, or an automatic color correction feature that will work
for minor color problems.

5. Is there a recommended method for adjusting the settings in KODAK DIGITAL SHO Professional?
When you bring up the KODAK DIGITAL SHO Professional Plug-In, the default
values of the plug-in will automatically be applied to the image. If
these results are not satisfactory, we recommend you first zoom out so
that you can see the entire image, then switch to the "Threshold"
preview mode. Adjust the threshold slider to set the areas of the image
that will be treated as shadows and lightened, and which will be
treated as highlights and darkened. Once the threshold value is set, if
the image is mostly too dark, adjust the shadow slider until you like
the results. If the highlights need to be darkened, first choose
between the "Film" and "Digital" modes. In general, the "Film" mode is
a stronger darkening effect and works best with images scanned from
film or taken with Digital SLR cameras and that haven't been highly
compressed. The "Digital" mode is a more subtle darkening, and is
designed to avoid obvious contours when darkening highlights that have
been quantized. The "Digital" mode works best on images scanned from
prints, or that have been highly compressed. The final step is to
adjust the color saturation level of the image.
