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 concepts. 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.

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.
