Re: Roy's working space blocks up shadow detail? Why use it?

Hi John,

Thanks for sharing your ideas on this issue.  I have not created any
curves and am using the curves provided with QTR or posted on this forum
(Ilford Smooth Pearl). Also, I am using a Windows XP system, so I have
to convert the file to the ICC profile in Photoshop that I want to
print. Sorry, but I am new to QTR and  am a little confused by your
suggestions.

Are you referring to QTR curves when using the word "profiles"? (I think
of profiles as ICC profiles). If so, then to strip out the
linearization, do you mean to open the curve in QTR Curve Creator and
under the linearization tab clear the numbers? To reinstall, does this
mean save the adjusted curve or does it mean use the "create curve"
button?

Here do you mean,  to convert the image to  a different output space icc
profile, such as the  QTR Gray Photo paper? Or do you mean to use the
original QTR curve (with the original linearization numbers)?

What do you mean by "using the install script". I have no "install
script" file in the QTR folder.

What is the difference between the "QTR-Linearize-Data" and the
"QTR-Create-ICC" scripts in the eye-one folder?

Thanks for all of your help
