No, it's an RGB-mode image; it's just that the only colors I'm using in it are white and gray.

Here's the smooth one again, along with a new one created in GIMP with the same dimensions as the smooth one: http://nodivisions.com/stuff/ext_posts/smooth-gradient.jpg http://nodivisions.com/stuff/ext_posts/gimp-unsmooth-gradient-smaller.jpg That one's better, but still has more visible striations than the non-GIMP image. Or by "range" are you referring to white-to-gray vs. white-to-blue? Am I running out of intermediate colors faster because white and gray are more similar than white and blue? Ideally what I'd like is a white radial gradient with a transparent background, approx. 800px wide and 25% opaque, which I could then overlay on any colored background in different situations. But I guess the color of the background will affect how smooth the gradient appears. Still, I can't seem to re-create that non-GIMP smooth gradient using GIMP, even on the same color background.
