Dear Karl
As CMYK is a much reduced colour space compared to RGB I would have thought
that made it exactly the case. The true test would be to make multiple
conversions from RGB to CMYK and back and see if quality suffered, which of
course it does.
The real test would be to make the
Firstly, if the results were as per your example I would look for a new
RGB-CMYK and/or CMYK-RGB conversion profile. Even visually the colors are
different.
If, however, such a result should be, then the 16 points are 6% of the total
gamut which is sufficient to adjust the green - I can't

I would like to get a $350-$450 scanner to make scans
of slides to produce 8x10 prints on either an Epson
870 or Canon S800 inkjet printer.
How about the Canon FS2710? Probably in your price range.

We are new into the film scanner environment and looking for some assistance
in advance of making of decision on several issues. As amateur ice hockey
photographers we shoot in very poor light. We are currently contemplating a
Nikon 4000 scanner to work in concert with Photoshop 6.0. We

Here's a question for Lawrence and others who might have 1200ppi flatbed HP
scanners (or similar):
Have you noticed that JPEGed flatbed image files are considerably smaller
than the same pictures scanned with your filmscanner?
I've noticed that scans scanned from prints with HP PrecisionScan

My own feeling is ... to enlarge clearly to 11 x 14, you need the
entire 35mm film frame ... especially for
Keep in mind that 1200x1200 is about 80% fewer pixels than 2700x2700. Also,
since you mentioned that you are describing jpg file size, that the
different applications may be using differing levels of jpg compression.

This could be due to a couple of factors. If there is any tendency for the
flatbed to produce a softer image it will compress to a smaller
AFAIK you pictures will scan with the same clarity (which is excellent
clarity) whether you shoot with the 300 or 400 lens, so the lens decision is
not in any way tied or related to the scanning of the resulting images.

It is my understanding that flatbeds generally do not pick up the detail
that a filmscanner does at the identical resolution. Since there is less
detail there are more areas of 'sameness' which, I assume, uses less space
for the JPEG algorithm to describe, whether compressed or uncompressed.

Silverfast behaves quick and good together with my LS 4000.
Now we are talking scanning speed compare to the slow NikonScan.
CMYK is not a reduced color space compared to RGB. Printer CMYK is. But
that is because the color space of the inks is more reduced. In essence,
this isn't any different than manipulating The Zone System - ie where the
dynamic range of paper is less than the dynamic range of film, which in

OK. Are you suggesting that some sort of CMYK settings in Photoshop could
make the CMYK mode's gamut more similar to RGB, and thus reduce the losses
in RGB to

I'm not a photoshop expert. I do know a bit about the abstract math behind
the colorimetry. I don't see why you would not be able to do what you
suggest.

Consider this
CMY are the complimentary colors of RGB. This means that according to color
theory, you can mix any color in RGB that you would want to with CMY.
The difference is that K is gray scale - intensity if you will. So what
that means is that if you were to look at a plot of the color
