Hi all !
I'm a Mars enthusiast from Europe and new to this board. Having been reading here for quite a while I'm sure this is one of the very best places on the web to discuss the mars missions (first I only knew the also excellent bad-astronomy board before I discovered this board that seems to see a bit more traffic though I'm especially intersted in the very good graphical/art/image-enhancing work done by members here. So let me share one of my own colorized navcam pics: original black/white navcam shot "larrys lookout from cumberland ridge" colorized version However: the colors are probably off from the "true color" as obtained by radiance-calibrated multi-band-filter composite images ... but on the other hand this gives the colorizing process some more degrees of freedom for that "artistic margin" ... We do not know the "real true" mars colors anyway ... I've been experiencing with colorizing black/white mars pictures for quite a while. first I thought It'd be impossible to get sensible results out from the "one-band" b/w navcam pictures ... but in the mean time, at least for some pictures, I'm beginnnig to get interesting results |

Here is linked my last attempt to render the marvelous Sol 438 Navcam Pan from Spirit; 180° view; stitched with POV-ray; synthetic upper sky, Thyra rim enhanced; (NB: a 360° pan is doable with Sols 437-438-439-440 pictures!). Hope you will enjoy:

QUOTE (spaceffm @ Mar 31 2005, 01:59 AM) well now i tried a new method by combining R and G ( 70% 2 30% ), than B and G ( 70% 2 30% ) and than combining all ( R+G,B+G,G ) It is quite difficult... Result not yet perfect but on the way i would say:) : Great results, spaceffm, but I don't understand if you really used images taken with varius filters or not... to me, it seems a monochromatic image! Moreover, I'm a POV-ray user and in your previous post you mentioned POV-ray used for stitching... how do you made? Finally, it seems to me that your panorama include a dust devil in the left side... I'right? Bye, Marco. -------------------- I always think before posting! - Marco -

I'right? Bye, Marco. THX, For stitching i used a normal commercial panorama software, is POV Ray a software? I never mentioned that i used this software? to do so. Edit: i see erwan has explained it already... Here is how i did the coloring: Loaded original BW panorama image. Changed color balance in midtone region to 100% red. Saved image. Loaded fresh copy of the BW panorama image. Changed color balance in midtone region to 100% green. Saved image. Loaded fresh copy of the BW panorama image. Changed color balance in midtone region to 100% blue. Saved image. Reloaded red channel image. Layered green channel image onto red channel image base, 50% opacity. Layered blue channel image onto red/green channel image base, 50% opacity. Decreased brightness, increased contrast across entire image area. I learned this method on this site: http://www.lumiere.net/~fib/mer_enhance.html How can i get than real filtered images if bw is "monochromatic" ? |

spaceffm, erwan
excellent work ! I've only recently started with the panorama stitching work but still struggling with problems like "dark banding" and ugly distortions ... erwan: your latest panorama stitching is nothing but perfect seamless and without any deformations ... I'm sure even JPL couldn't do better than this spaceffm: I like the little sun-effect you added to the image very much ! That's what adds "the icing of the cake" to such images (similar to the mars image enhancements done by the famous space artist Don Davis, who always adds some subtle artistic touch to his image enhancements: http://www.donaldedavis.com/2003NEW/NEWSTUFF/DDMARS.html e.g. the "limb" bending of the horizon in the Olympus Mons image or his beautiful color interpretations of the pathfinder /viking sunset images ... ... oh, i'm getting carried away QUOTE but I don't understand if you really used images taken with varius filters or not... to me, it seems a monochromatic image! QUOTE yeah, that's the most difficult part: to colorize b/w images without getting a "monochromatic look" The image ("Larry's Lookout") I posted above is one of my best attempts to colorize a single-band image with almost realistic, non-monochromatic look ... BTW: doesn't the martian landscape look a bit too "monochromatic" anyway, even in "true color" pictures |

Hi folk, keep on, keep on in this great trend and we needn't more wait for JPL pans
The time will come where JPL itself save the costs for own pans -------------------- |
