Title: Shaded Relief controls
Post by: KenF on October 03, 2009, 08:00:54 AM

Shaded relief is a nice addition.
Is it my imagination or has the original shading method been tweaked?

I had noted that it seemed to create a noticeable reduction in contrast (haziness) on the non-shaded portions of a color view. Maybe that's inherent in the shading method. Seems to be better now than in the beta version.

In the controls for shaded relief "Darkness" seems to operate non-intuitively since the shading is lightened as the slider is moved to the right.

For the "lighting angle" control, instead of a 1-100 scale, it would to be preferable to have a 0-360 control so that a solar position could be easily simulated by number. For example, high noon lighting would be a setting of 180.   Since that's just a matter of the displayed scale it should be very easy to implement.  Along the same lines, a circular graphical control would be nice too.

Yep, I was able to improve the blending of the relief to not fade out non-shaded hillsides.  It was definitely an improvement over the beta version.

Agree that darkness could be reversed.

And also on the lighting scale.  I couldn't find a circular control that was easy but in minimum it should be 0-360.

Thanks for the thoughtful suggestions.

I hit both of these suggestions with the current beta.  Thanks.
