What’s New in Photoshop CS3 Extended 11
interoperability between Photoshop and MATLAB via the MATLAB command line. Now,
researchers and scientists can access Photoshop CS3 Extended directly from the MATLAB
command prompt. at access makes it easy to grab image data from Photoshop, use
MATLAB to run dierent image processing routines, and then return the image data to
Photoshop to instantly view the results. As
the routines are changed in MATLAB, the
changes are visualized in Photoshop CS3
Extended.
Image Stack processing
Not to be confused with thumbnail stacks in
Adobe Bridge, Image Stacks in Photoshop
CS3 Extended refers to a new level of
automated processing you can apply to a
series of images contained in the layers of a
Photoshop document. For example, a
radiologist can easily see the maximum pixel
value across a stack of images, or stack
thousands of images of a single patient, each
one a single “slice” of their body. A photo
shoot may result in dozens of photographs of
the same subjects—Image Stack processing can help combine the elements of all of them to
produce a more perfect single shot. Combining images in this way could be done in
Photoshop before—manually and painstakingly. In Photoshop CS3 Extended, Image Stacks
are the rst step in a eld of automated image processing that is just opening up, thanks to
the improved power and capability of today’s computers. Run Image Stack processing on
any group of images, simply by opening a new Photoshop document with each image on its
own layer, grouping the layers into a new
Smart Object, and choosing
an option from the Layer >
Smart Objects > Stack
Mode menu.
Black and White
conversion
Advanced black-and-white
conversion is simpler and
faster, with a brand new
Black and White
adjustment that helps you
quickly remap the colors in
your image to monochrome,
and improvements to the
Channel Mixer.
In the Black and White
adjustment, one button
analyzes the image and oers conversion
settings. You can ne-tune with simple sliders
that control the conversion of each color—
even interactively adjust channels in the large preview. Just click an image area to highlight
the appropriate color slider, or click and drag an image area to instantly adjust the
Simple, intuitive,
point-and-click
monochrome
conversion is yours
with the new Black
and White
adjustment.
The Channel Mixer is one of many
features that gains the exibility in
Photoshop CS3 to save and recall
custom presets.
