week 3 fruit-vendor (neutrals)

[mikemeister_admin]

interesting experiment with neutrals.
I am not finished yet with manipulating the curves manually.
the point is, I have placed 6 neutrals.
but you can find them back on the curve-channels.
there are 5 active on red and blue, but 4 on green.
I know there must be a difference in brightness  but ...... ?
when i make then individually active , the clock hand changed and also one or two neutrals are not neutral anymore.
How must I handle this ?

More neutrals is usually not a good idea.  In this exercise, rather than using multiple neutrals, the object is to either place one neutral in a strategic place, or to manually adjust the curves to get the hands on the hue clocks as short as possible.

If you would like to experiment with a large number of neutrals, this can be done, but the results are unpredictable.  Normally you would only use from 1 to 3 neutrals, being careful that they are spaced along the curve.  In RGB this is done by placing neutrals on colors that are spread out along the curve.  Otherwise you will get kinks like the ones you see in the green and blue channel.

In some cases, when the color space does not support additional neutrals, or the curve shape would contain negative bends, curvemeister will refuse to use a neutral, the most common example of this more than one neutral in Lab mode.  When this happens, a small red X appears in the center of the neutral. You can manually give priority to a particular neutral (or other pin) by clicking on it.

after your message i did again a lot of experimenting with less or more neutrals.
I could not get a better picture then yours.
So i continue with the lesson.
