Color Manage Your Scans
    Color Think Pro is unquestionably the premier color management software.

    CHROMiX ColorThink™ color management tool-set helps you understand
    color better than ever before.
    The ColorThink tool-set is an application composed of nine modules for
    visualizing, evaluating & solving color problems.
    We highly recommend CHROMIX Color think Pro: All the images in the
    forthcoming eBook from ScanScience

    One of the of the most important decisions you are likely to make in scanning is the is the tagging your image with a working color space. Once you
    do that, the image is forever confined to the boundaries of that color space. The colors contained in the film that the working color space can't
    include, are permanently lost (clipped) to the scan and can't be recovered. Choosing, -after the fact, a wider color space in Photoshop is ineffective:  
    The loss is permanent and can not be undone.

    In scanning, the objective of color management is to record with maximum fidelity the colors embedded on film.  If you have scanned and captured all
    the colors in the film faithfully, the image's richness may not be fully evident in the monitor at hand, but since printers have wider gamuts than most
    monitors, the printer may print most colors in the scan even though you can not see them in the monitor. The richness of the colors in the scan are not
    lost, because the monitor does not display them or the current printer can't print them, they are embedded with the scan waiting to come to life and
    rescued by a better monitor or printer.

    Opting for fluid-scanning puts within reach the highest quality reproduction possible. To ensure it, the path from the scan to the print must be direct,
    as regards size and color settings, with the least amount of intervention by the photo-editor software. Best quality requires sizing the scan for the
    print and tagging the optimum working color space to the image from the start.  This means a color space that will not clip the colors on film nor one
    that will be too wide as to include artificial, mathematically created colors. If this is done, the colors resident on the film will stand better chance of
    being reproduced in print.  Although  Color Science can be complicated, the working principles are not difficult and distill into relatively basic

    Older color spaces and older printers were blind to a large portion of the visible spectrum including blues and greens. A weak color space like
    sRGB was then quite appropriate, because what it could not capture could not be printed anyway. The very wide color gamut reproducible in
    today's best printers requires a larger color space to match, fortunately new color spaces are available that more closely match the capabilities
    of the best printers. The only remaining shortcoming is in the media, (paper), which at its best,  falls short of reproducing the full brightness or
    intensity recorded in film, which is readily viewable in projection, a monitor, or a light-table.  

    A very large color space like Pro-Photo RGB is big enough to encompass all real colors, but at the price of including many unreal, imaginary
    colors. When sRGB was the only game in town, the distorted colors produced by pro-Photo RGB might have been worth the risk and a better
    choice than clipped colors. The imaginary colors in Pro-Photo RGB are merely mathematical constructs, devoid of practical significance, which
    can lead to severe distortions of the real colors. By today's standards Pro-Photo RGB has seen its best days.

    A large set of comparisons of many color spaces against the gamuts of several monitors and many printers is one of the many features in the
    forthcoming eBook, and these will help you attain the best color possible with fluid scanning. This eBook is

    Like the highly regarded eBook "Total Scanning", which is available now from ScanScience, and is included on Total Scanning +, it will have the
    same built-in interactivity and linked-references to many interesting topics that take you right to the topic discussed at the source, the same feature
    that  made Total Scanning the ideal reference and teaching aid.
Nature is generous with color and the human eye the
marvelous gift that enables it.
To do both justice you need  to understand the color
capabilities of color spaces and printer profiles, which you
learn in ScanScience's forthcoming eBook
"Total Scanning 2"
The image above compares the color gamuts of 1- An old color space, sRGB,  -which many photographers still use, in 3D, 2- the color
profile of an inexpensive, amateur printer circa 2009, also in 3D and 3- The CIE LAB gamut of visible colors shown as the base in 2D.  As
can be seen, both the sRGB color space (shown in the wire-frame) and the printer's profile (shown in the solid format), come far short of
reproducing all visible colors, but the sRGB color space fails to fit the least. In it most greens fall widely short of the printable gamut of even
this very inexpensive amateur printer. The blues (which are not shown in this take, are equally clipped as would be seen if the image would
be turned around.
The best color printers of today in conjunction with the latest color spaces, come closer to reproducing a larger portion of the visible
spectrum. sRGB is the color space lamentably used in many point and shoot digital cameras, which are incapable of fine color reproduction.

Passing  the mouse over the image shows you the advantage of having the latest printer, -which  is wasted if you tag you scan with sRGB.
You will notice that many of the greens and blues not captured in sRGB would be printable with this printer.
