I already posted a tutorial about alpha-curves that are good for shaping the alpha-channel. In this tutorial its all about Value or Chrome-Curves.
The channel of the curves-tool is set to the default of 'Value' (instead of Alpha).
Chrome-Curves are a way of shaping a
gradient (for example), into something that looks metallic or chromed.
(40ies) Grey to White
(#666666 - #ffffff)
Chrome-Curves can have all sorts of
shapes, from simple to extreme.
Basically its a wavy shape that goes up
and down along the diagonal line in your curves diagram or, in the
more extreme cases, from bottom to the top of the curves-tool dialog-box.
Here are some examples:
Curves applied to the gradient filled text:
See how the gradient changes, the more i manipulate the curve.
Bevelled Text
For the next demonstration im adding a
bevel to our text and then apply custom chrome-curves.
See how tweaking the
curve, step by step, changes the chrome look:
More examples for chrome-curves shaped gradients:
Chrome-Curves on a bumpmapped layer:
Finally a different approach:
bumpmapping a 50ies grey layer with a 6px blurred channel and then
chrome-curves.

These curves give a beautiful effect in texts. It's always nice to save some of these curves in presets.
I always get confused if I use the "curve-tool" in value or Alpha. But as there are only two options, it is not as big a mess as well.
Thx for all Esper!
I was thinking about uploading some curves-presets, but i think its totally unnecessary.
Distinguishing alpha and value curves is quite easy. If you want to change the colour, you use Value. If you want to manipulate the shape and/or transparency, then use alpha.
Ahhh! Now it's easy! If color then Value, else, Alpha! This tip made things more transparent. It was a tip "Alpha"! lol. Thx Esper!
