About curve blending function

2012-07-11 by Sylvain M.

Hi all,

I would like to know something about Curve Blending: where
are the limits between each zone (Highlights, Midtones, Shadows)? How
does QTR make the transitions?
For example: if I set Highlights to
Curve1:80, Curve2:20, and then Midtones to Curve1:20, Curve2:80, where
is the limit (let say: on a 21step test file), and how is the
transition?

Many thanks,

Sylvain.

As Paul says just try it.
But really its very simple: its just 3 points 0,50,100 with straight lines
connecting them.  Since its all continuous you can't detect any transitions.

Thx Roy. 

So you mean that the Highlights values in % are taken
for 100, then midtones values for 50 and shadows values for 0, am I
right? And between each value, the % is kind of progressive, that's all?

Re: About curve blending function

Roy

This has just prompted a query from myself.

What if you are blending two curves

Curve 1 UT14-7DSMatt-cool 70% highlights   ?% midtones   ?% shadows
Curve 2 UT14-7DSMatt-warm 30% highlights   ?% midtones   ?% shadows

7DSMatt is 7dayshop.com matt paper.

Re: [QuadtoneRIP] Re: About curve blending function

2012-07-15 by Roy Harrington

Mel,

I don't see how your question is different.
It just does the most obvious, simple thing.  70% of cool curve inks +
30% of warm curve inks.
There's nothing mysterious or fancy about it.

So that means

Curve 1 70% highlights 70% midtones 70% shadows
Curve 2 30% highlights 30% midtones 30% shadows

Am I correct ?

Yes, without split toning all tones are the same.
