Correcting foreshortening

Dennis

I use a 3D render filter in Photoshop. Newer versions of photoshop do not have this filter with the basic installation. Its a bit hard to describe how the filter works on email (I showed it to people at last years astrofest). I first place the image on a map of the whole moon obtained from VMA. I then load this image into Photoshop and place a circle (via the 3D transform filter) around the Moons edge. This converts the 2D image of the moon into a sphere. Then I use the 3D render filter controls to rotate the sphere so that the desired crater is seen from "above". Save image.

This is an apalling description. I will give a talk at the AAQ meeting in November (14th I think) at the Brisbane planetarium. I will bring my computer to demonstrate these and other functions.
