Re: UT7 - Apply Roark or Staver curves or both?

2005-08-25 by dave_in_gva

Hi Daniel,

Long time no write. My kids are still happy here in Geneva with that 
print you sent us.

Thanks for clearing up the curve question - I thought that was the 
answer but wanted to be sure. BTW I see curves in the Files section 
here and on your Petraflux site for Carbon, Cool and Sepia for EEM. 
No neutral as far as I can see....

Also, my preferred method of converting my digital captures to 
monochrome (after experimenting with many)is John Paul Caponigro's 
method which consists of bringing into an RGB file any or all of the 
RGB channels plus or minus the luminance channel as separate (and 
therefore, monochrome) layers and editing their effect on the image 
through layer masks. What I like about this method is the ability to 
handle the conversion differently in different parts of the 
image...similar to PKS sharpening I suppose. More for those 
interested is here:

This leaves me with an RGB, as opposed to a grayscale file...this 
makes no difference (I would assume) to working with the files in QTR 
I assume, correct?

I'm sure you'll put the new densitometer to good use and I'll be 
happy to continue using your curves Daniel - in fact up until now I 
have been working with the UT2 inks and your curves from way back 
when...

Warm regards,

Dave
