You need to upgrade your Flash Player The theme of this blog is not only and obviously space, but in particular “terrestrial worlds”, places that tend to have surfaces on which one could walk or at least attach oneself to. These places sometimes also have other earth-like familiar features such as atmospheres, weather, volcanos, geysers and perhaps, we are finding, even exotic oceans, rivers or lakes that are not necessarily made of familiar materials we are used to here at home. The second theme is imagery. Occasionally I do some retouching of images when needed if an image is incomplete or sometimes “dirty” or noisy. I will attempt to correct image shortcomings based upon other images or well-accepted presumed attributes. When this is done, notes will be offered as to what was added, why and sometimes how it was done. This way no one should ever wonder if something they are looking at is real or photoshop.

Rolf Olsen Photo Renders Neptune

The above is an interesting project to image the full Neptune system based on actual data returned by Voyager. According to the article published along with the imageRolf Wahl Olsen composed this scene from actual images from the departing Voyager probe. The rings (which were never photographed in their entirety) are based on over-exposed images and then density mapped to a model which was applied to the scene. Even the stars are based on one of the over exposed images of the rings which revealed what the probe would have seen and that field data was inserted from and image generated by Google Sky.
