Thanks, it was an afterthought really, but I'm glad I did it. My brain definately sees the terrain better in perspective, even though I am not seeing an new pixels.
I added a little extra info about the project on my blog: Venus in Perspective |

I added a little extra info about the project on my blog: Venus in Perspective Very interesting and well-done. One question: the "channel" in the mid-field of the image on your blog page seems suspiciously aligned with the edges of the image coverage. Is there really reason to think this is anything but an artifact of your processing? I wouldn't want people doing photogeology on the basis of seeing this feature if there isn't real evidence for it. -------------------- Disclaimer: This post is based on public information only.

The persective images are derived from superimposing different projections, with photoshop. I explain that on my latest blog entry. Geologists would not use an image like that to do any kind of analysis. They are just meant to convey the big picture of what the terrain looks like, in a familiar camera perspective. For photo interpretation of geology, you would look at the new unprojected images, with the improved radiometric response function, or even the individual perspective projections, like the three partitial images I show. Soviet researches, at one time, reprojected the Venera images into the cylindrical form returned by the Viking Mars lander, to help make comparisons in a projection that planetary geologists had become use to studying. |

Well done, Don.
You've managed to make me beat my shortest-lived wallpaper ever record, when yesterday's stunning LPOD Plato shot was bumped off my monitors this morning to be replaced with your Venusian Hills. Beautiful imagery - I have to agree with David with regards to making Venus a place, with work as good as this. Andy |
