local contrast tool feedback

[McCap]

After some more playing with this tool I am guessing that the darknesss and lightness levels are basically what I did in this tutorial with the curves on the detail masks.

Refined unsharp masking for local contrast

Refined Unsharp Masking for Local Contrast This tutorial is done in Gimp, but the basic ideas could be applied in any other layer based software (like photoflow, etc…) Original Image Notice that all images shown in this tutroial, except the original image here, were resized for faster upload speed.

This also leads me to two suggestions:

1. Add a selectable luminance range for this tool, like in the wavelets contrast tool.

2. Maybe allow for more than one instance of the local contrast tool. This way you could do what I did in above mentioned tutorial and you could also add contrast on different scales. How to implement this I dont know exactly. Multiple local contrast tools would just look stupid. Something like in the local lab version, where you can select a number of control points would be good. In this case I don’t think that more than two or three instances of this tool would make any sense. The advantage of this over CbD or wavelets contrast (where I already have multiple levels) is that one could make instances work on different luminosity ranges and the ability to fine tune darkness and lightness makes it much more controllable.

What do you think?
