Harald Heim ContrastMaster is a plug-in for effective contrast enhance-ment as well as creating dramatic
contrast looks, photorealistic paintings and HDR-like effects. It can turn low-contrast photos into
vivid and detailed images and transforms ordinary photos into interesting and dynamic shots.
ContrastMaster works with dozens of graphics applications including Adobe Photoshop, Paint Shop Pro,
Photoshop Elements, Photo-Paint, IrfanView and PhotoImpact under Windows. For accelerated rendering it
supports hyperthreading as well as multiple processors and cores. ContrastMaster works with 8bit and
16bit RGB images.
ContrastMaster v1.0 offers three local and four global contrast adjustment methods as well as various
masking, saturation and brightness options. The three local adjustment methods allow you to dramatically
improve contrast in small image details without blowing out highlights or damaging the image. You can
apply these three methods separately or use various options to mix them together for even better
results.
The four global methods (S/H-Contrast, Stretch, Equalize and Polarize) work on the tonal range of the
image and help to improve the result even further. There is also an option for changing the brightness
of the image. The masking options let you conveniently remove the ContrastMaster effect from an image
area where you do not want to have it applied, e.g. skin areas, a blue sky or a wall. This can be done
with the help of shadow/highlight and color masking options. Additionally, a saturation mask feature
lets you improve saturation without oversaturating the image.
Sophisticated Algorithms.
- ContrastMaster offers three sophisticated methods for enhancing contrast in small image details. They
are called Dynamic, Adaptive and Local. In fact, these three methods utilize five algorithms in total,
because the dynamic and adaptive methods each use another algorithm for certain control settings. Each
of these algorithms adjusts the contrast of image details in its own special way, which makes
ContrastMaster useful for different types of images and allows you to produce a variety of effects and
looks.
Each of the three methods lets you adjust the size of the image details that are affected, the effect
intensity and the way the contrast is adjusted. Additionally, the Dynamic Contrast methods lets you
avoid artifacts or noise without lowering the effect intensity, the Adaptive Contrast methods
automatically adjusts image details of different size at the same time, and the Local Contrast methods
lets you independently increase and decrease the contrast in image details as well as influence the
brightness character of the effect. Each of the three methods also offers special shadow/highlight
adjustment options as part of the algorithm.

For Beginners as well as Experts - ContrastMaster offers six modes from the simple Novice mode to the
sophisticated Expert Mode. Whereas Novice and Expert mode let you apply all contrast effects at the same
time, the remaining four modes let you apply each of the three local effects and all the global effects
individually. Moving the mouse over a control displays a detailed explanation in the Help box, so you
don't need to read the manual before using ContrastMaster.
Each of the seven tab sheets offers a button menu with various local presets for quickly applying useful
settings. Furthermore, there is a global preset feature that allows you to save and reuse useful
settings later. Several global presets are already delivered with ContrastMaster. There is a FX Values
check box on the Prefs tab for using strong instead of medium effect intensities as the defaults. That
way people who mainly want to produce special effects with ContrastMaster do not need to readjust
sliders all of the time. ContrastMaster also lets you adjust up to three different effect settings at
the same time and switch between them by using the Preview tab sheets, so you can experiment with
different effect settings and conveniently compare them without leaving the ContrastMaster dialog.
Why ContrastMaster Is Different - There is no other tool available that offers as many methods for
contrast adjustment as ContrastMaster.
ContrastMaster is not only more effective at squeezing image details and contrast out of photos than
most other tools, it also offers more options for fine-tuning and controlling image contrast than any
other tool. Additionally, the Adaptive Contrast method is not available in any other software.
You can also use ContrastMaster to give a single photo the look of a HDR image while avoiding the
overhead of HDR photography. With its masking options you often do not need to create selections or
layer mask for selectively applying the ContrastMaster effect, which saves you a lot of time.
ContrastMaster also offers special features that are not found in most other tools, e.g. spilt views,
logged settings, 17 histogram types, own defaults, blown highlights detection, rendering time
estimation, novice/expert modes, local presets and preview tab sheets.
