Open the clouds.jpg.
Open your TerraGen
rendering in PSP. Hold down the shift key and hit the D
once. This will duplicate your image. Close your original image.
Image > Resize > pixel size of about 400 x 300, all layers checked.
Effects > Sharpen > Sharpen.
Activate your clouds picture.
Click on the copy
Activate your rendering.
Edit > Paste > As a new layer.
On your layer palette change your layer blend mode from Normal to Screen.
Slide the layer opacity to about 50%.
Now do you like how your fog looks? If not try Image > Flip and/or
Image > Mirror.
That will change where the fog lays.
Now just frame with your favorite method.
Merge your layers
and save as a .gif or .jpg.
