    Question on "Rendering Clouds"

    rollsnut Community Member

      I am on a PC using CS4

       

      I am wondering if there is a way to change the shape of the clouds in the RenderClouds filter? Too many times it looks a bit unnatural and I would like to create a "whisperier" look or sometimes a bigger cloud or a bigger cloud and smaller ones around it, etc.. I have tried playing with "Blur" and "Smudge" but still not getting anything decent.

       

      Also, are there any sets of blue color codes (R, G, B) that are the most common for a natural looking "sky blue" that could be used?

       

      Thanks in advance for any direction\hints.

          I have tried to get a softer cloud formation from render/clouds also.

           

          What i ended up doing was just getting a cloud brush from deviantart.com and just using that.

           

          As far as having the proper color of white or blue, i find that the cloud brushes color very well, so it is easy to make it look more natual. I will often open a picture of the sky and just use the eye dropper for color.

           

          I know this isn't the proper answer, but it is what i use for a work around. Good luck.

            For the Blue, open an image with a nice sky, and use the Eyedropper to make a swatch of it.

             

            For using Clouds (the filter) to make clouds, try experimenting using Levels and Curves on them.

             

            If you use the Perspective option withFree Transform, you can make them recede to the Horizon.

             

            Since the scale of the rendered clouds (Perlin noise) depends on the size of the image, I'll run Clouds on two or three different-size blank docs, then scale and combine them into one doc as layers. With the Free Transform technique I mentioned, you can transform each layer differently, to get the effect of high clouds and low clouds.

             

            If you do the clouds as black/white, rather than blue/white, on a separate layer, you can set the blending mode to Lighten or Multiply, and drop them into an existing sky image.
