Appearance of the TIFF v. RAW

Here is the comparison of the picture, saved in JPEG, TIFF and RAW, and
then manipulated to "pull" out the details:

As you can see, RAW is better than JPEG or TIFF.

You *cannot* view a "RAW" image! Your conclusion is not valid.

The RAW file is sensor data. It is *not* an image. The data
*must* be converted to some standard image format for viewing.

Hence you can convert it to TIFF with one program, and to JPEG
with another, and then compare those two.

But neither of them is more or less than the other a
represention of the RAW data as such. Any differences are the
result of using different conversions to different formats. If
you have a third conversion (for example a thumbnail generated
in the camera and embedded into the RAW file) it is *not* any
different than the TIFF or the JPEG in not being a direct "view"
of the RAW data. It too is just a product of a different
conversion program.

You should be working on these types of corrections in the raw conversion
process and not. afterwards. What tools are you using? Are both color
managed applications using the same monitor profile?

your question about the monitor profile being shared by CS2 and RSP, I
fully admit I'm not sure. How would I check this?

In RSE (maybe similar to RSP) click the top-left green icon and select
'Preferences' and at the bottom see "Using monitor profile: ..."

In CS (probably same in CS2, they haven't changed this since rev 6) do
Edit - Color Settings - and in the Working Spaces box for RGB click the
icon to open the list, then scroll to the top of the list and look for
"monitor RGB" ... should have the same ICC monitor profile listed here
as in RS.

Both programs should have picked these up automatically from the system
preferences so you should see the same profile.

An additional thing to check is the working color space of both program the
same?

Yes, sRGB.

That's not a monitor profile, that's the working color space.
In RSE your profile will be found by pulling down the left most top menu
next to the green dot and choosing preferences. At the bottom of the
General tab it will say:

Using monitor profile: XXXXXXXXX

And it says (verbatim): sRGB IEC61966-2.1

Also, the Bypass color management (Expert option) should not be checked.

Not checked.

It doesn't sound like you have calibrated your monitor to create a profile
or are not using a generic monitor profile from the manufacturer from what
you are saying. Remember we went through this before and I did a test with
one of you raw files and saw no difference on my system between the
converted and RSE preview.

I've been through this with a couple of different people, and nothing
has worked. I've calibrated the monitor, the color space is the same,
the profiles are the same, but the images are not.
