Re: [Digital BW] Adjusting MIS VM curves

2001-11-15 by Intro234@aol.com

Paul,
Thank you so much for your advice.

I do have your curves for the 1200 but I wanted to start with something 
simple. I tried adjusting yours but made a mess of it because of their 
complexity. The problem I am having with your curves is little 
differentiation between the steps in the darker midtones that wipe out most 
of the detail in those areas. The lighter areas come out pretty accurate. 

I started with no curve at all using all the inks and made a transfer 
function for that. The wedge came out pretty good but the midtones were a 
little too cool, so I decided to do a neutral curve by adding green to the 
midtones. 

Thanks for telling me to use the "yellow" ink to compensate when I reduce the 
blue, I did not think of that. I am quite comfortable with Photoshop so I do 
know how to use Curves.

By the way, what do you mean by toner? The lighter blue ink? I am very new to 
all of this so please bear with me.

Another elementary question: how close do you try to get the RGB values for a 
neutral print? I print the wedge, scan it, set the black and white point and 
then measure the RGB and K values with the eyedropper. (I hope I am doing 
that right.) My RGB readings for my neutral curve are within 1-4 units of 
each other for each step. Is that close enough? 

Also, how do you decide on the RGB values for the toned prints? That's my 
next step after I master the neutral one.

Thanks again,

Marketa
