PFP 2.0 - Extended grays for color images

PFP 2.0 - Extended grays for color images

2006-11-29 by ed_limmy

Hi david & dave,
Is it ok to ask questions about PFP2.0 here so that others can also 
view it? Anyway, here it is.

what's the effect of the extended grey/gray(?) patches on the color 
profiles? does it make for more details and graduations in the 
gray/black areas?


in PFP2.0, I don't understand the 'Open Profile' function. WHen i 
activate it, i get to choose from a range of my existing profile but 
i then get windows xP then asks me to choose a software/application 
to use the profile - which of course stops me from using it further.


Thank-you.

Regards,
Ed.

(I think at this point, it's OK, but I'll let David T answer if he's
willing. Plus, I'm too busy to answer today..:-)

I'll let David T answer that one.

Oh, that one's easy. It's just a shortcut command for you to open the folder
on your system that contains the profiles you've built! It's not for PFP
functionality, this is just a convenience. Maybe it should be named "Open
Profile Folder..." instead, and it wouldn't have been confusing that way.
(But then the menu commands start to get "long"...)

This command is for techies, who might want to use a 3rd party profile editor
to actually look at the contents of the profile; or to find and copy it to
another location. You don't need to use this command as part of the normal
workflow of -building- profiles in PFP; and you also don't need to do
anything special to "install" the profile; once it's created and in the
right place (which is the folder that "Open Profile" opens up for you),
all color managed applications on your system should have access to it.

Not the general idea with beta testing, but this is so close to the end of the process that it doesn't really matter...

profiles? does it make for more details and graduations in the
gray/black areas?


Yes, it does. Think of one of those metal tube apple corers. When you add the data from the grays and near grays in the Extended Grays target, it replaces a thinly sampled core of gray data with a much more extensively sampled core. So even for color prints, there is more gray, near gray, black near black, white, near white data.


in PFP2.0, I don't understand the 'Open Profile' function. WHen i
activate it, i get to choose from a range of my existing profile but
i then get windows xP then asks me to choose a software/application
to use the profile - which of course stops me from using it further.

I'll let Dave Miller get back to you on that; certainly having Windows stomp on things in the middle of the process is not the intent.

Yes, Pls rename it 'Open Profile FOLDER'. It would help 
tremendously. Otherwise it would suggest that a profile can be 
accessed and something can be done to the profile......

Thank-you.
