I am using M$ Paint to create a bitmap and then Photoshop to do a Gausian
Blur on this image to smooth everything out so as I have some nice hills. I
have no problem with the x and z resolutions (6000*6000 is probally a bit
over the top for my purposes, but what the hell) but the y resolution is
limited to 256 levels (8 bit greyscale). I would much prefer this to be
16bit greyscale but Photoshop won't do the Gausian Blur (or any blurs for
that matter) when I set this pixel depth to this.
Does anyone have a solution for my problem?
Thanks Alot, Aly.

If you don't have any special reason to draw it by hand, you can create
nice height_fields directly with another POV-Ray scene, or internally with
the beta version and the function image pattern.

The only reason to draw it by hand is it's so much easier to have my hills
and lake where I want them.

Yes, if you want precise control you need a paint program. Anyhow, this
can also be done to some extent with another scene, using an old trick with
spotlights. See crater.pov on the sexample scenes.

How to get really high-quality heightfields: don't use greyscale.
Use colour. Your lowest elevation is still &H000000 and
highest is still &HFFFFFF, but you can step through all
16777215 values and have a much smoother heightfield.

Your Freudian slip is showing.

Try *lowering* the resolution. If the resolution is low enough, then the
separations between levels will be less obvious. Of course, you might not be
able to afford too low of a resolution. I don't really know what the
solution is; I've never gotten a hight field to really look good.
