Textures are becoming a little more familiar to me, but I've still been befuddled as to how to have texture/color show up on blown-out, detail-less skies (which is something I capture frequently here in SoCal). This particular tutorial at Shadowhouse, along with the available canvas texture, walked me thru the steps to put texture on a blank sky. Wanna see?
Before (notice the detail-less sky):
Here's a screen shot of my layers (with modes and opacities labeled).
And here's the "after".
I know my "after" is not an earth-shattering piece of art, but I'm just so tickled to have the texture "stick" to the sky, and I'm anxious to try the technique on other images. :-)
Now, go visit Shadowhouse, be inspired, learn, and download some textures!
