I'm guessing I don't need to explain what's going on in the picture... Some post rendering work done in photoshop. I'm having some trouble putting in a second sun that casts enough light to make a shadow, but doesn't look completely unnatural or skew the entirecolor scheme. I want to put it in the upper right corner (above the sand dune/Mountain). Any suggestions for a light source (radial with what settings... etc.) I don't even need to see the light source, actually. I can add a visible one in photoshop later. I just need the shadow. My other problem is that no matter what I do, even though the image looks good in photoshop, when I export it in any format (set at maximum quality) I get that sectional gradient looking sky, instead of a smooth gradient. Any ideas about settings in Photoshop would help. Thanks.
